$Δ$ 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…

Comparison of the mixed-fermion-action Effects using different fermion and gauge actions with 2+1 and 2+1+1 flavors

Zun-Xian Zhang, Mengchu Cai, Bolun Hu +4

The leading-order low-energy constant $Δ_{mix}$ in mixed-action chiral perturbation theory is calculated using $2 + 1 + 1$ -flavor gauge ensembles with HISQ fermions and a tadpole-i…
