Abstract The shape of the Bs0Dsμ+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 Bs0Dsμ+νμ decay is reconstructed through the decays DsDsγ and DsKK+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.
