Search for the semi-leptonic decays And

Physics Letters, 2023
We search for the semi-leptonic decays Λc+→Λπ+π−e+νe and Λc+→pKS0π−e+νe in a sample of 4.5fb−1 of e+e− annihilation data collected in the center-of-mass energy region between 4.600GeV and 4.699GeV by the BESIII detector at the BEPCII. No significant signals are observed, and the upper limits on the decay branching fractions are set to be B(Λc+→Λπ+π−e ...

Hyperon semileptonic decays in QCD sum rules

Journal of High Energy Physics
We investigate the hyperon semileptonic decays within the framework of QCD sum rules. The flavor SU(3) symmetry breaking effects are analyzed via the relevant form factors and corresponding branching fractions.

Effective field theory analysis of rare |∆c| = |∆u| = 1 charm decays

Journal of High Energy Physics
We perform a global analysis of |∆c| = |∆u| = 1 transitions using recent data on D 0 → μ + μ − , D + → π + μ + μ − , Λ c → p μ + μ − , and D 0 → π + π − μ + μ − decays, and work out constraints on new physics Wilson coefficients C 7 , 9 , 10 ′ $$ {C}_{7 ...
