First Measurement of the $D_{s}^{+} \to K^{} (892)^{0} μ^{+} ν_{μ}$ Decay, Study of Dynamics and Test of Lepton Universality with $D_{s}^{+} \to K^{} (892)^{0} ℓ^{+} ν_{ℓ}$ Decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +715

We report the first measurement of the semileptonic decay $D_{s}^{+} \to K^{*} (892)^{0} μ^{+} ν_{μ}$ and an improved measurement of the decay $D_{s}^{+} \to K^{*} (892)^{0} e^{+} ν_{e}$ usin…

Measurement of the Absolute Branching Fraction of Xi(1530)^{-} to (Xi pi)^{-} and Updated Measurement of the Branching Fraction of psi(3686) to anti-Xi^{+} Xi(1530)^{-} + c.c

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

Based on (2712.4+-14.3)*10^{6} psi(3686) events collected with the BESIII detector, the decays Xi(1530)^{-} to Xi^{0} pi^{-} and Xi(1530)^{-} to Xi^{-} pi^{0} are investigated join…

Search for the charmonium weak decay $ψ (2 S) \to D_{s}^{-} π^{+} + c . c .$ and $ψ (2 S) \to D_{s}^{-} ρ^{+} + c . c .$

BESIII Collaboration, M. Ablikim, M. N. Achasov +720

We search for the weak decays $ψ (2 S) \to D_{s}^{-} π^{+} + c . c .$ and $ψ (2 S) \to D_{s}^{-} ρ^{+} + c . c .$ for the first time. The search is based on $(2712.4 \pm 14.3) \times 1 0^{6}$ events containing th…
