Improved measurement of the absolute branching fraction of inclusive semileptonic $Λ_c^+$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov, P. Adlarson et autres

Using $4.5 \mathrm{fb}^{-1}$ of $e^+e^-$ annihilation data samples collected at center-of-mass energies ranging from 4.600 to 4.698 GeV with the BESIII detector at the BEPCII collider, we measured the absolute branching fraction for the inclusive semileptonic decay $Λ_c^+\rightarrow Xe^+ν_e$, where $X$ refers …

Observation of the decay D0→ρ−μ+νμ

М. Н. Ачасов, P. Adlarson, S. Ahmed, M. Albrecht et autres

By analyzing an ${e}^{+}{e}^{\ensuremath{-}}$ annihilation data sample corresponding to an integrated luminosity of $2.93\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we measure the branching fraction of the ${D}^{0}\ensuremath{\rightarrow}{\ensuremath{\rho}}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}{\ensuremath{\nu}}_{\ensuremath{\mu}}$ decay for the first time. We …
