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…
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…
2021 Update on with lattice QCD inputs
Jeehun Kim, Yong-Chull Jang, Sunkyu Lee +4
We present recent updates for determined directly from the standard model (SM) with lattice QCD inputs such as , , , , , $ξ…
Strange and charm contributions to nucleon charges and moments
Rui Zhang, Tanmoy Bhattacharya, Rajan Gupta +4
We present preliminary results for strange and charm contributions to nucleon charges and moments. The scalar, axial and tensor charges, and unpolarized first moments are calculate…
Nucleon Momentum Fraction, Helicity and Transversity from 2+1-flavor Lattice QCD
Santanu Mondal, Rajan Gupta, Sungwoo Park +4
High statistics results for the isovector momentum fraction, , helicity moment, , and the transversity moment, $\langle x\rangle…
