The LHCb experiment started its physics program with the 37/pb of pp
collisions at 7 TeV c.m. energy delivered by the LHC during 2010. The
performances and capability of the experiment, conceived for precision
measurements in the heavy flavour sector, are illustrated through the first
results from the experimental core program. A rich set of production studies
provide precision QCD and EW tests in the unique high rapidity region covered
by LHCb. Notably, results for W and Z production are very encouraging for
setting constraints on the parton PDFs.Comment: Proceedings for the "XIX International Workshop on Deep-Inelastic
