$Δ$ resonance contributions to QED radiative corrections in neutron and inverse beta decay

Oleksandr Tomalak, Yi-Bo Yang

We incorporate the $Δ (1232)$ resonance into pion-induced QED radiative corrections to neutron decay and inverse beta decay (IBD). Within the framework of heavy-baryon chiral pertur…

Radiative corrections to the nucleon isovector $g_{V}$ and $g_{A}$

Oleksandr Tomalak, Yi-Bo Yang

Electroweak, QCD, and QED radiative corrections to the nucleon low-energy coupling constants $g_{V}$ and $g_{A}$ are enhanced by large perturbative logarithms between the electroweak a…

Impact of Dynamical Charm Quark and Mixed Action Effect on Light Hadron Masses and Decay Constants

Tong-Wei Lin, Zun-Xian Zhang, Mengchu Cai +8

We investigate the impact of including a dynamical charm quark on the properties of light hadrons. Our study compares the calculations performed on 2+1+1 flavor (HISQ fermion) ense…
