Measuring open charm hadron production at 7 TeV using the LHCb detector

Using data taken by the LHCb detector at $\sqrt{s}~=~7~\text{TeV}$ during 2011 the normalised double differential production cross-sections of $D^0$, $D^{*+}$, $D^+$, $D_s^+$ and $L_c^+$ are presented in bins of rapidity and transverse momentum. Comparisons are also made to the previous LHCb measurement at $\sqrt{s}~=~7~\text{TeV}$. and, where available, to theoretical predictions obtained using the FONLL model. This analysis has been developed for the start of LHC Run 2 where the LHCb collaboration will repeat this measurement at $\sqrt{s}~=~13~\text{TeV}$.
