Electroweak box diagrams on the lattice for pion and neutron decay
Jun-Sik Yoo, Tanmoy Bhattacharya, Rajan Gupta +2
CKM matrix is unitary by construction in the standard model(SM). The recent analyses on the first row of CKM matrix show tension with unitarity. Nonperturbative calcu…
Lattice QCD and Particle Physics
Andreas S. Kronfeld, Tanmoy Bhattacharya, Thomas Blum +79
Contribution from the USQCD Collaboration to the Proceedings of the US Community Study on the Future of Particle Physics (Snowmass 2021).
AI and Theoretical Particle Physics
Rajan Gupta, Tanmoy Bhattacharya, Boram Yoon
Theoretical particle physicists continue to push the envelope in both high performance computing and in managing and analyzing large data sets. For example, the goals of sub-percen…
Improved data analysis on two-point correlation function with sequential Bayesian method
Tanmoy Bhattacharya, Benjamin J. Choi, Rajan Gupta +7
We report our progress in data analysis on two-point correlation functions of the meson using sequential Bayesian method. The data set of measurement is obtained using the Okta…
The pion-nucleon sigma term from Lattice QCD
Rajan Gupta, Tanmoy Bhattacharya, Martin Hoferichter +3
We summarize recent evidence, both from lattice QCD and chiral perturbation theory, that suggests that larger-than-expected excited-state contamination could be the reason for the…
Flavor Diagonal Nucleon Charges
Sungwoo Park, Tanmoy Bhattacharya, Rajan Gupta +4
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…
