Strong CP Violation and large- spin-flavor symmetry
Thomas R. Richardson
We revisit the contribution of the QCD term to the CP violating pion-nucleon couplings and the nucleon electric dipole moment in a combined large- and chiral perturb…
The role of intermediate states in nucleon-nucleon scattering in the large- and unitary limits, and and scattering
Thomas R. Richardson, Matthias R. Schindler, Roxanne P. Springer
We explore potential explanations for why using large- ( is the number of colors) scaling to determine the relative size of few-nucleon low-energy operators agrees with e…
Towards the determination of CP-odd pion-nucleon couplings
Shohini Bhattacharya, Kaori Fuyuto, Emanuele Mereghetti +1
The nucleon matrix elements (NMEs) associated with quark chromo-magnetic dipole moments (cMDMs) play a crucial role in determining the CP-odd pion-nucleon couplings induced by quar…
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…
