First observation and measurement of the branching fraction for the decay Bs0 → Ds∗∓K± [PDF]

open access: yes, 2015
A bstractThe first observation of the Bs0 → Ds∗∓K± decay is reported using 3.0 fb−1 of proton-proton collision data collected by the LHCb experiment. The Ds∗∓ mesons are reconstructed through the decay chain Ds∗∓ → γDs∓(K∓K±π∓).

Angular analysis of the decay B0→K⁎0μ+μ− from pp collisions at s=8 TeV

open access: yesPhysics Letters B, 2016
The angular distributions and the differential branching fraction of the decay B0→K⁎(892)0μ+μ− are studied using data corresponding to an integrated luminosity of 20.5 fb−1 collected with the CMS detector at the LHC in pp collisions at s=8 TeV. From 1430

Exclusive D s semileptonic branching fraction measurements [PDF]

open access: yes, 2015
We measure absolute branching fractions for six exclusive $D_s$ semileptonic decays. We use data collected in the CLEO-c detector from $e^+e^-$ annihilations delivered by the Cornell Electron Storage Ring with a center-of-mass energy near 4170 MeV.
