First minimum bias physics results at LHCb

Abstract

The goal of the LHCb experiment is the indirect search for New Physics through precision measurements of B-decays. A short description of the detector and its performance after the first data taking in 2009 and 2010 will be presented. In addition first preliminary results of a $\rm K_{s}$ differential cross section measurement at a center of mass energy of $\sqrt{s} = 900\; \rm GeV$ and a measurement of the $\frac{\bar{\lambda}}{\lambda}$ production ratio at $\sqrt{s} = 900\; \rm GeV$ and $\sqrt{s} = 7\; \rm TeV$ will be discussed.
