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-…
