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…
Misaligned jets from Sgr A and the origin of Fermi/eROSITA bubbles
Kartick C. Sarkar, Santanu Mondal, Prateek Sharma +1
One of the leading explanations for the origin of Fermi Bubbles is a past jet activity in the Galactic center supermassive black hole Sgr A. The claimed jets are often assumed…
Study of accretion flows around an ultraluminous X-ray source M82 X-1 using NuSTAR data
Santanu Mondal, Biswaraj Palit, Sandip K. Chakrabarti
We study the spectral properties and accretion flow behavior of an ultraluminous X-ray source M82\,X-1 using {\it NuSTAR} observations. We use the physical two component advective…
Variable mass accretion and failed wind explain changing look phenomena in NGC 1365
Santanu Mondal, Tek P. Adhikari, Krzysztof Hryniewicz +2
Changing look active galactic nuclei (CLAGNs) show complex nature in their X-ray spectral shape and line of sight column density variation. The physical mechanisms responsible for…
Flux and spectral variability of Mrk 421 during its moderate activity state using NuSTAR: Possible accretion disc contribution?
Santanu Mondal, Priyanka Rani, C. S. Stalin +2
The X-ray emission in BL Lac objects is believed to be dominated by synchrotron emission from their relativistic jets. However, when the jet emission is not strong, one could expec…
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…
Excited states and precision results for nucleon charges and form factors
Rajan Gupta, Tanmoy Bhattacharya, Vincenzo Cirigliano +8
The exponentially falling signal-to-noise ratio in all nucleon correlation functions, and the presence of towers of multihadron excited states with relatively small mass gaps makes…
