description	Abstract The shape of the B s 0 → D s ∗ − μ + ν μ $$ {B}_s^0\to {D}_s^{\ast -}{\mu}^{+}{\nu}_{\mu } $$ 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 B s 0 → D s ∗ − μ + ν μ $$ {B}_s^0\to {D}_s^{\ast -}{\mu}^{+}{\nu}_{\mu } $$ decay is reconstructed through the decays D s ∗ − → D s − γ $$ {D}_s^{\ast -}\to {D}_s^{-}\gamma $$ and D s − → K − K + π − $$ {D}_s^{-}\to {K}^{-}{K}^{+}{\pi}^{-} $$ . 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.
