$U$ -spin sum rules for two-body decays of bottom baryons

Si-Jia Wen, Wei-Chen Fu, Di Wang

$U$ -spin symmetry, which reflects the symmetry between the down-type $d$ and $s$ quarks, is a powerful tool for analyzing heavy hadron weak decays. Motivated by recent experimental…

$C P$ asymmetries in the $I^_{c}^{+} \to p K_{S}^{0}$ and $I^_{c}^{+} \to I^£^{+} K_{S}^{0}$ decays

Di Wang, Si-Jia Wen

$C P$ asymmetry is a crucial element in interpreting the matter-antimatter asymmetry in the universe and searching for new physics beyond the Standard Model. In this work, we study…

Isospin sum rules for bottom-baryon weak decays

Wei-Chen Fu, Si-Jia Wen, Di Wang

Isospin symmetry, as the most precise flavor symmetry, can be used to extract information about hadronic dynamics. The effective Hamiltonian operators of bottom quark weak decays a…
