DESCRIPTION:Speakers: Ms. ON\, Alvina Yee Lian (Mullard Space Science 
 Laboratory\, University College London)\nThe cosmic web is permeated by 
 large-scale magnetic fields\, which are generally weak but can still leave
  observable imprints in the radio sky. Therefore\, Rotation Measure 
 Fluctuation (RMF) analysis at radio wavelengths is commonly used to 
 diagnose cosmic magnetism. It is argued that the length-scales on which 
 magnetic fields vary in large-scale\, diffuse astrophysical media can be 
 inferred from correlations in the observed RM. In this poster\, we assess 
 the usage of RMF analyses for magnetic field diagnostics in the framework 
 of polarised radiative transfer. We simulate various models of magnetic 
 fields and electron densities to investigate how density fluctuations 
 could affect the correlation length of magnetic fields inferred from the 
 conventional RMF analyses. We caution against interpretations of RMF 
 analyses when a characteristic density is ill-defined\, e.g. in the cases 
 of log-normal distributed and fractal-like density structures. Lastly we 
 discuss the implications of our work on future radio observations and 
 highlight how machine learning would be particularly useful when the 
 Square Kilometre Array (SKA) is expected to be able to measure over ten 
 million extragalactic RMs.\n\nhttps://agenda.hepl.phys.nagoya-u.ac.jp/indi

DESCRIPTION:Speakers: Ms. FUJIWARA\, Motoko (Nagoya University)\nIn this 
 presentation\, we propose a new electroweakly interacting spin-1 DM model.
  We consider the non-Abelian extension of electroweak symmetry. Namely\, 
 we extend the SU(2)_L group in the Standard Model(SM) into the direct 
 products of three SU(2) groups. We also impose the exchange symmetry 
 between two of these SU(2) groups to stabilize the spin-1 DM candidate. In
  this setup\, the DM pair annihilate into SM particles through the 
 electroweak interaction efficiently. Therefore\, we obtain the correct DM 
 energy density via the freeze-out mechanism while evading the current 
 strict bounds from the DM direct detection experiments. We show the 
 parameter region where we obtain the correct DM energy density and discuss
  the future detectability of this model. This talk is based on JHEP 07 
 (2020) 136 [arXiv:2004.00884].\n\nhttps://agenda.hepl.phys.nagoya-u.ac.jp/

SUMMARY:Breakout room #1: Bayesian fit analysis to full distribution data

DESCRIPTION:Speakers: Mr. IGURO\, Syuhei (Nagoya University)\nWe 
 investigate the semi-leptonic decays of B→D^(∗)ℓν in terms of the 
 Heavy-Quark-Effective-Theory (HQET) parameterization for the form 
 factors\, which is described with the heavy quark expansion up to 
 O(1/m_c^2) beyond the simple approximation considered in the original CLN 
 parameterization. An analysis with this setup was first given in the 
 literature\, and then we extend it to the comprehensive analyses including
  (i) simultaneous fit of ∣Vcb∣ and the HQET parameters to available 
 experimental full distribution data and theory constraints\, and (ii) New 
 Physics (NP) contributions of the V_2 and T types to the decay 
 distributions and rates. For this purpose\, we perform Bayesian fit 
 analyses by using Stan program\, a state-of-the-art public platform for 
 statistical computation. Then\, we show that our ∣Vcb∣ fit results for
  the SM scenarios are close to the PDG combined average from the exclusive
  mode\, and indicate significance of the angular distribution data. In 
 turn\, for the SM+NP scenarios\, our fit analyses find that non-zero NP 
 contribution is favored at the best fit point for both SM+V_2 and SM+T 
 depending on the HQET parameterization model. A key feature is then 
 realized in the B→D^(∗)τν observables. Our fit result of the HQET 
 parameters in the SM produces a consistent value for RD while smaller for 
 RD^∗\, compared with the previous SM prediction in the HFLAV report. On 
 the other hand\, SM+V_2 points to smaller and larger values for RD and 
 RD^∗ than the SM predictions. In particular\, the RD^* deviation from 
 the experimental measurement becomes smaller\, which could be interesting 
 for future improvement on measurements at the Belle II experiment.\n\nhttp

DESCRIPTION:Speakers: Mr. BISWAS\, Diptaparna (University of 
 Louisville)\nKlongs are identified by hit patterns in KLM\, the outermost 
 detector at the Belle II experiment. However some photons and other 
 neutral hadrons can also give hits in KLM. We present here a statistical 
 technique using sPlot\, to distinguish between hits pattern in KLM from 
 K-longs vs other backgrounds directly from data. This technique allows one
  to make a robust determination of K-long reconstruction efficiency in the
  KLM detector.\n\nhttps://agenda.hepl.phys.nagoya-u.ac.jp/indico/contribut

DESCRIPTION:Speakers: KIMURA\, Yuto (Hiroshima University)\nIn recent 
 years\, machine learning(ML) has begun to be used to find out small signal
  of gravitational wave(GW) from noisy data and to estimate physical 
 parameters of it. The approach is an alternative to using templates\, by 
 which the parameters are estimated by matching with theoretical models. 
 George and Huerta (2018) demonstrated the ML method for GW from binary 
 black holes. It is important to explore the possibility of detection and 
 estimation for different types of GW signals. We consider the possibility 
 of detection and parameter estimation for GW burst by ML. Since the wave 
 forms\, e. g.\, driven by magnetar giant flares\, are uncertain at 
 present\, we model them and explore the ability of the ML approach. We use
  the same algorithms based by convolution neural network used in binary 
 black hole merger by George and Huerta (2018). In this poster\, we discuss
  accuracy of detection and how much error we can estimate parameters.\n\nh

DESCRIPTION:Speakers: Ms. HIRATA\, Hikari (Nagoya University)\nIn the Belle
  II experiment\, a distributed computing system is utilized for not only 
 saving and processing huge data but also analyzing it for the physics. 
 However\, around 10% of analysis jobs submitted into the system were 
 failed in 2019\, due to errors in analysis scripts. Such failed jobs make 
 computing resources waste\, and they have potential to trigger the system 
 troubles. In order to suppress failed analysis jobs\, we developed a new 
 framework. In the framework\, syntax in the scripts is checked every 
 before submitting analysis jobs. Moreover\, when huge analysis jobs are 
 submitted\, a few test jobs are submitted on the system for the sanity 
 check. In this poster\, the details and the development status will be giv
 en.\n\nhttps://agenda.hepl.phys.nagoya-u.ac.jp/indico/contributionDisplay.

DESCRIPTION:Speakers: Mr. HALDER\, Soumen (Tata Institute of Fundamental 
 Research)\nBelle II\, the successor to the Belle experiment\, has begun 
 data collection since 2019 aiming to record 50 ab-1 data at a peak 
 luminosity of 8✕1035 cm-2s-1\, which is 40 times higher than Belle. 
 Charged leptons form an essential ingredient for many interesting physics 
 channels at Belle II. In particular\, an accurate reconstruction of the 
 electron’s energy is important as it radiates bremsstrahlung photons. 
 This radiation is more prominent when the electron passes through a high-Z
  material. At Belle II\, the energy of electrons is measured with the 
 electromagnetic calorimeter (ECL). Before reaching the ECL electrons must 
 pass through an inner tracking system\, comprising silicon pixel and strip
  vertex detector\, which leads the former to radidate. Due to the 
 bremsstrahlung radiation the measured energy of electrons is changed with 
 respect to when they are produced via some process. To mitigate this 
 situation\, the bremsstrahlung photons are searched for around the 
 electron’s track direction and four momenta of such photons are added 
 with the electron to recover its momentum. In this poster we describe the 
 Bremsstrahlung recovery framework and its performance with the current 
 dataset of Belle II.\n\nhttps://agenda.hepl.phys.nagoya-u.ac.jp/indico/con

DESCRIPTION:Speakers: Mr. KOBAYASHI\, Ryuta (Nagoya University)\nThe NEWSdm
  is a directional dark matter search experiment. In this experiment\, we 
 aim to detect the recoiled nuclei tracks induced by dark matter by using 
 Nano Imaging Tracker (NIT)\, a solid track detector\, and detect the 
 direction of the tracks. NIT has high spatial resolution and can record 
 sub-μm track information created by recoiled nuclei by dark matter. 
 Currently\, in order to conduct experiments on the 10 kg ・ year scale\, 
 analysis machines is being developed. these make it possible to do 
 automatic and high speed read out sub-μm track information stored in the 
 NIT. In this presentation\, I am going to talk about the development 
 status and future prospects of the analysis machine.\n\nhttps://agenda.hep

DESCRIPTION:Speakers: Mr. ODAGAWA\, Takahiro (Kyoto University)\nNeutrino-
 nucleus interaction is one of the major sources of the systematic 
 uncertainty for neutrino oscillation experiments. To reduce the 
 uncertainty\, it is important to measure low momentum hadrons from the 
 interactions. The NINJA experiment uses a nuclear emulsion detector called
  Emulsion Cloud Chamber (ECC). Thanks to fine granularity and good 
 position resolution of the nuclear emulsion\, ECCs can detect low momentum
  charged particles especially protons down to 200 MeV/c. However\, ECCs 
 cannot identify the muon track by itself\, therefore a muon detector is 
 placed downstream of them and a scintillation tracker and an emulsion 
 multi-stage shifter are placed between them to connect the muon tracks. 
 From November 2019 to February 2020\, the NINJA experiment conducted its 
 first physics run with 75 kg water target exposed to a T2K neutrino beam 
 corresponding to 4.8e20 protons on target. The emulsion films are now 
 under scanning process and the neutrino event reconstruction is ongoing. 
 In this poster\, we will show the status of muon track matching between 
 the NINJA detectors and the neutrino event reconstruction using those muon
  tracks.\n\nhttps://agenda.hepl.phys.nagoya-u.ac.jp/indico/contributionDis

DESCRIPTION:Speakers: Mr. KOO\, Hanwool (KASI/UST)\nWe analyze the Joint 
 Light-curve Analysis (JLA) Type Ia supernovae (SN Ia) compilation 
 implementing the non-parametric iterative smoothing method. We explore the
  SN Ia light-curve hyperparameter space and find no dark energy model 
 dependence nor redshift evolution of the hyperparameters. We also analyze 
 the more recent Pantheon SN Ia compilation to search for possible 
 deviations from the expectations of the concordance ΛCDM model. We 
 demonstrate that the redshift binned best fit parameter values oscillate 
 about their full dataset best fit values with considerably large 
 amplitudes. At the redshifts below z≈0.5\, we show that such 
 oscillations can only occur in 4 to 5% of the simulations. This might be a
  hint for some behavior beyond the predictions of the concordance model or
  a possible additional systematic in the data. In addition\, we develop a 
 non-parametric approach using the distribution of likelihoods from the 
 iterative smoothing method. It determines consistency of a model and the 
 data without comparison with another model. Simulating future WFIRST-like 
 data\, we show how confidently we can distinguish different dark energy 
 models using this approach.\n\nhttps://agenda.hepl.phys.nagoya-u.ac.jp/ind
