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…
Unveiling the Strong Interaction origin of Baryon Masses with Lattice QCD
Bolun Hu, Haiyang Du, Xiangyu Jiang +3
Both the Higgs mechanism and strong interactions contribute to the masses of visible matter, yet how the six Higgs-generated quark masses and uniform strong interaction strength de…
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…
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…
