Measurement of the shape of the Bs0 → Ds∗−µ+νµ differential decay rate

LHCb Collaboration

Research output: Contribution to journalArticlepeer-review


The shape of the Bs0 → Ds∗−µ+νµ differential decay rate is obtained as a function of the hadron recoil using proton-proton collision data at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.7 fb1 collected by the LHCb detector. The Bs0 → Ds∗−µ+νµ decay is reconstructed through the decays D∗− → Dsγ and Ds → KK+π. The differential decay rate is fitted with the s Caprini-Lellouch-Neubert (CLN) and Boyd-Grinstein-Lebed (BGL) parametrisations of the form factors, and the relevant quantities for both are extracted.
