Semileptonic b → c ℓ ν decays are excellent probe for testing Lepton Flavour Universality and New Physics (NP) effects. A search for NP is performed with an angular analysis of B0 → D∗ µ ν decays in pp collision data collected by LHCb with an integrated luminosity of 3 fb−1. The signal is extracted using a multidimensional fit to data using templated distributions derived from simulation and from control samples in collision data. New Physics contributions are measured via their corresponding Wilson coefficients and in several fit configurations that allow for different New Physics operators. Form factor parameters using three parametrizations (BLPR, CLN and BGL) are measured in a Standard Model scenario.
