Physics with first LHCb data

The LHCb experiment is designed for hadronic flavour physics and will look for New Physics manifestations in the decay of charm and bottom hadrons abundantly produced at the LHC. All parts of the LHCb physics programme can be embarked on with the expected statistics to be collected during the first 2010-2011 physics run at $\sqrt{s}$ = 7 TeV. We present first preliminary results on strangeness production, and demonstrate, using the few nb$^{-1}$ of already collected data, the potential for initial measurements in heavy-flavour physics.
