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 ...

Testing lepton flavor universality at the Electron-Ion Collider

Journal of High Energy Physics
Measurements of b → cτ − ν ¯ τ $$ b\to {c\tau}^{-}{\overline{\nu}}_{\tau } $$ transitions at colliders are highly motivated for testing lepton flavor universality (LFU), a cornerstone hypothesis of the Standard Model (SM).

Radiative corrections to the muon polarization in the semileptonic decay of a neutral kaon

Journal of High Energy Physics
A model-independent expression for the Dalitz plot of the semileptonic decays of a neutral kaon K μ 3 0 $$ {K}_{\mu 3}^0 $$ , including radiative corrections to order O $$ \mathcal{O} $$ [(α/π)(q/M 1)], where q is the four-momentum transfer and M 1 is ...
