Sumario:B_d -> D* mu+ nu will be one of the highest statistics exclusive channel reconstructed in LHCb and can be used as control channel for calibrations, in particular for measuring flavour tagging performances. The reconstruction and selection of this channel is described, as well as the studies on the B meson momentum and proper time reconstruction and on the flavour tagging performances. An expected yield in 2 fb-1 of about 9 millions selected and triggered events is obtained, with a background over signal ratio of 0.26.
