resonance contributions to QED radiative corrections in neutron and inverse beta decay
Oleksandr Tomalak, Yi-Bo Yang
We incorporate the 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 and
Oleksandr Tomalak, Yi-Bo Yang
Electroweak, QCD, and QED radiative corrections to the nucleon low-energy coupling constants and 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…
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 in mixed-action chiral perturbation theory is calculated using -flavor gauge ensembles with HISQ fermions and a tadpole-i…
Spontaneous chiral symmetry breaking and mass gap of QCD in finite volume
Xiaolan Meng, Bolun Hu, Yi-Bo Yang
We present the lattice QCD simulation with the 2+1+1 flavor full QCD ensembles using near-physical quark masses and different spatial sizes , at 0.055 fm. The results su…
