BESIII has collected 4.5 fb^-1 of e+e- collision data between 4.6 and 4.7 GeV. This unique data offers ideal opportunities to study Lambda_c+ decays. We will report the partial wave analysis of Lambda_c+ -> Lambda pi+ pi0 and the observations of Cabibbo-suppressed Decays Lambda_c+ decays, including Λ+c → nπ+ etc. In addition, we will report the form factor measurement in Lambda_c+ -> Lambda e+...
The Belle II experiment at the SuperKEKB asymmetric-energy electron-positron collider has been collecting the world’s highest-intensity collisions at the $\Upsilon$(4S) since 2019. A data set comparable in size to that of predecessor experiments, and collected with the new detector, enables unique or world-leading results. Examples include indirect searches for non-standard-model physics in...
The heavy flavor rare decays allow exploring energy scales much higher than the ones directly accessible and present good chances to search for the beyond the Standard Model phenomena. Several observables, such as the branching fractions, the R values and the angular distribution parameters, are utilized to enhance the searching for BSM in the flavor rare decays, because of their sensitivities...
We explore the semileptonic and nonleptonic decays of doubly heavy baryons $(\Omega_{cc}^ {(*) +}, \Omega_{bb}^ {(*)0}, \Omega_{bc}^ {(*)-}, \Omega_{bc}^{\prime0}) $ induced by the $s\to u$ transition. Hadronic form factors are parametrized by transition matrix elements and are calculated in the light front quark model. With the form factors, we make use of helicity amplitudes and analyze ...
