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-…

Accurate B meson and Bottomonium masses and decay constants from the tadpole improved clover ensembles

Mengchu Cai, Hai-Yang Du, Xiangyu Jiang +4

We present a determination of the bottom quark mass, the masses of S-wave bottom mesons, and their decay constants using an anisotropic clover fermion discretization for the heavy…

Lattice QCD calculation of charmed baryon decay constants at continuum limit and physical mass

Lei-Yi Li, Jie Ran, Meng-Chu Cai +10

We present the first principle calculation of charmed baryon decay constants employing 2+1 flavor gauge ensembles with lattice spacings ranging from 0.05 to 0.1 fm and pion masses…

Charmed meson masses and decay constants in the continuum from the tadpole improved clover ensembles

Hai-Yang Du, Bolun Hu, Mengchu Cai +10

We present the determination of the charm quark mass, the masses, and decay constants of charmed mesons using thirteen 2+1 flavor gauge ensembles at five different lattice spacings…
