We 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 comprehen

In 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 annihilat

The 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 cor

Belle 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 bremsstrahlu

Klongs 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 reconstructi

In 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

The 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 experi

Neutrino-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

The J-PARC muon g-2/EDM experiment is under development with a new approach. Compared to the previous experiment, this experiment will use lower emittance muon beam with a smaller storage ring. The 300 MeV/c muon will be injected into the 3 T MRI-type solenoid storage magnet. Tracking detector will measure the momentum of decay positrons with time in the storage magnet. We discuss our track recons

We 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 expectati

In 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 ex

KAGRA is gravitational wave interferometer in Japan. This experiment can be sensitive to not only gravitational wave but also environmental noise like electric noise, earthquake, and sound. My research is to identify such hardware related signal excess from true gravitational signal using auxiliary data of environmental monitor and so on.
