The B0s→D∗−sμ+νμ decay is reconstructed through the decays D∗−s→D−sγ and D−s→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.32 p.application/pdfengcc-by (c) LHCb Collaboration et al., 2020https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article7104902022-05-04info:eu-repo/semantics/openAccess
