New sum rules from exact -spin degeneracy
Chao-Qiang Geng, Chia-Wei Liu, Sheng-Lin Liu +1
We propose a new class of sum rules in the -spin limit, based on the observation that the weak phase in the Standard Model can be removed in the degenerate limit .…
Puzzles in charmed baryon semileptonic decays with flavor symmetry and lattice inputs
Chao-Qiang Geng, Chia-Wei Liu, Sheng-Lin Liu
Recent measurements of charmed-baryon semileptonic decays signal large tensions between experiment and theory, including analyses and lattice-quantum chromodynamics simul…
Spin-flavor entanglement in and weak phase extraction
Yong Du, Chao-Qiang Geng, Xiao-Gang He +3
We identify a new spin-flavor entanglement structure in decays, formed by the correlation between the spin and the flavor states ($D=D^0,\overline D^0,D_1,D_2…
Two-body charmed baryon nonleptonic weak decays with decuplet baryon involving SU(3) breaking effects
Chao-Qiang Geng, Chia-Wei Liu, Sheng-Lin Liu
We study the singly charmed baryon two-body decays of under flavor symmetry, where refers to anti-triplet singly…
