Measurements of $B^0$ mesons production cross-section in pp collisions at $\sqrt{s}$ = 7 TeV using $B^0 \rightarrow D^{*-}\mu^+ \nu_\mu X$ decays

This note presents the measurement of the $B^0$ meson production cross-section in $pp$ collisions at $\sqrt{s}$ = 7 TeV using semi-leptonic decays reconstructed in the channel $B^0 \rightarrow D^{*-}\mu^+ \nu_\mu X$. The measurement is performed with data collected with the LHCb detector at the LHC in the pseudorapidity interval $2<\eta<6$ using an integrated luminosity of 14.9 $nb^{-1}$.
