Abstract

The shape of the Bs0→Ds∗−μ+νμ differential decay rate is obtained as a function of the hadron recoil parameter using proton-proton collision data at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 1.7 fb⁻¹ collected by the LHCb detector. The Bs0→Ds∗−μ+νμ decay is reconstructed through the decays Ds∗−→Ds−γ and Ds−→K−K+π−. The differential decay rate is fitted with the Caprini-Lellouch-Neubert (CLN) and Boyd-Grinstein-Lebed (BGL) parametrisations of the form factors, and the relevant quantities for both are extracted.
