Search for New Physics with an angular analysis of $B^0 \to D^\ast \mu \nu$ decays and alignment of the LHCb Vertex Locator / Mitreska, Biljana
A search for New Physics was performed with an angular analysis of $B^0 \rightarrow D^* \mu \nu$ decays in $pp$ collision data collected by the LHCb experiment during 2011 and 2012, corresponding to an integrated luminostiy of 3 $\rm fb^{-1}$ [...]
