Spectral Properties of GX~339--4 in the Intermediate State Using AstroSat Observation
Arghajit Jana, Debjit Chatterjee, Hsiang-Kuang Chang +2
We present the results obtained from the spectral studies of black hole X-ray binary GX~339--4 using \astrosat~ observations during its 2021 outburst. \astrosat~ observed the sourc…
Electroweak box diagram contribution for pion and kaon decay from lattice QCD
Jun-Sik Yoo, Tanmoy Bhattacharya, Rajan Gupta +2
One of the sensitive probes of physics beyond the standard model is the test of the unitarity of the Cabbibo-Kobyashi-Maskawa (CKM) matrix. Current analysis of the first row is bas…
Broadband X-ray spectral analysis of the ULX NGC 1313\,X-1 using JeTCAF: Origin of the ULX bubble
Biswaraj Palit, Santanu Mondal
NGC 1313\,X-1 is a mysterious Ultra-luminous X-ray (ULX) source whose X-ray powering mechanism and a bubble-like structure surrounding the source are topics of intense study. Here,…
Spectral and Temporal Studies of Swift\,J1658.2--4242 using {\it AstroSat} Observations with {\tt JeTCAF} Model
Santanu Mondal, V. Jithesh
We present the X-ray spectral and temporal analysis of the black hole X-ray transient Swift J1658.2--4242 observed by {\it AstroSat}. Three epochs of data have been analysed using…
Evolution of low frequency quasi-periodic oscillations in GX 339-4 during its 2021 outburst using AstroSat data
Santanu Mondal, Anirudh Salgundi, Debjit Chatterjee +3
The black hole X-ray binary GX\,339-4 showed an X-ray outburst during 2021. The {\it AstroSat} captured this outburst when the source entered into the intermediate flux state while…
Update on Flavor Diagonal Nucleon Charges
Sungwoo Park, Tanmoy Bhattacharya, Rajan Gupta +3
This talk provides an update on the calculation of matrix elements of flavor diagonal axial, scalar and tensor quark bilinear operators between the nucleon ground state. The simula…
Nucleon form factors and the pion-nucleon sigma term
Rajan Gupta, Tanmoy Bhattacharya, Vincenzo Cirigliano +8
This talk summarizes the progress made since Lattice 2021 in understanding and controlling the contributions of towers of multihadron excited states with mass gaps starting lower t…
