• First Measurement of the $D_s^+\rightarrow K^{*}(892)^0\mu^+\nu_{\mu}$ Decay, Study of Dynamics and Test of Lepton Universality with $D_s^+\rightarrow K^{*}(892)^0\ell^+\nu_{\ell}$ Decays hep-ex · 2026-05-08 · accept · none · ref 38

  First measurement of Ds+ → K*(892)0 μ+ νμ branching fraction together with form factors and differential rates shows no lepton universality violation.

  Evidence at 3.6 sigma is reported for the semileptonic decays Lambda_c+ to Sigma^pm pi^mp e+ nu_e with branching fraction (7.7 +2.5 -2.3 stat +/- 1.3 syst) x 10^-4, consistent with quark-model predictions.
