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…
Precision Nucleon Charges and Form Factors Using 2+1-flavor Lattice QCD
Sungwoo Park, Rajan Gupta, Boram Yoon +5
We present high statistics results for the isovector nucleon charges and form factors using seven ensembles of 2+1-flavor Wilson-clover fermions. The axial and pseudoscalar form fa…
Contribution of the QCD -term to nucleon electric dipole moment
Tanmoy Bhattacharya, Vincenzo Cirigliano, Rajan Gupta +2
We present a calculation of the contribution of the -term to the neutron and proton electric dipole moments using seven 2+1+1-flavor HISQ ensembles. We also estimate the topolog…
Qubit regularization of asymptotic freedom
Tanmoy Bhattacharya, Alexander J. Buser, Shailesh Chandrasekharan +2
We provide strong evidence that the asymptotically free (1+1)-dimensional non-linear O(3) sigma model can be regularized using a quantum lattice Hamiltonian, referred to as the "He…
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…
State preparation and measurement in a quantum simulation of the O(3) sigma model
Alexander J. Buser, Tanmoy Bhattacharya, Lukasz Cincio +1
Recently, Singh and Chandrasekharan showed that fixed points of the non-linear O(3) sigma model can be reproduced near a quantum phase transition of a spin model with just two qubi…
