Lattice QCD calculation of the pion-nucleon coupling induced by the QCD -term
Fangcheng He, Tanmoy Bhattacharya, Rajan Gupta +1
We present lattice QCD results for the CP violating pion-nucleon coupling induced by the QCD term from the analysis of three 2+1+1-flavor ensembles generat…
Signs of Non-Monotonic Finite-Volume Corrections to
Zack B. Hall, Dimitra A. Pefkou, Aaron S. Meyer +10
We study finite-volume (FV) corrections to determinations of via lattice quantum chromodynamics (QCD) using analytic results and numerical analysis. We observe that H…
Gradient flow of the Weinberg operator
Tanmoy Bhattacharya, Shohini Bhattacharya, Vincenzo Cirigliano +5
We present preliminary results on the susceptibilities involving the CP-violating (CPV) Weinberg three-gluon operator and the topological term using the gradient flow scheme, a…
Neutron electric dipole moment from isovector quark chromo-electric dipole moment
Tanmoy Bhattacharya, Vincenzo Cirigliano, Rajan Gupta +3
We present results from our lattice QCD study of the contribution of the isovector quark cEDM (qcEDM) operator to the neutron EDM. The calculation was carried out on four 2+1+1-fla…
Quark Chromo-Electric Dipole Moment Operator on the Lattice
Tanmoy Bhattacharya, Vincenzo Cirigliano, Rajan Gupta +3
We present a lattice QCD study of the contribution of the isovector quark chromo-electric dipole moment (qcEDM) operator to the nucleon electric dipole moments (nEDM). The calculat…
nEDM from the theta-term and chromoEDM operators
Tanmoy Bhattacharya, Vincenzo Cirigliano, Rajan Gupta +2
In a previous work, we showed that unresolved excited state contaminations provide a major source of systematic uncertainty in the calculation of the nucleon electric dipole moment…
