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 ${\mathrm{K}}_{\mathrm{s}}$ differential cross section measurement at a center of mass energy of $\sqrt{s}=900\mathrm{GeV}$ and a measurement of the $\frac{\bar{\lambda }}{\lambda }$ production ratio at $\sqrt{s}=900\mathrm{GeV}$ and $\sqrt{s}=7\mathrm{TeV}$ will be discussed.
