Minimum Bias Measurements with ALICE at the LHC

Abstract

ALICE (A Large Ion Collider Experiment) is one of the seven experiments at the the Large Hadron Collider (LHC) at CERN, Geneva, Switzerland. ALICE is especially designed for heavy-ion collisions but it also operates a rich proton-proton (pp) program. ALICE has collected pp collision data at $\sqrt{s}=$ 0.9, 2.36, 2.76, and 7 TeV and lead-lead (Pb--Pb) collision data at $\sqrt{s_{\mathrm{NN}}}=$2.76 TeV. Here, we report minimum bias measurements obtained until the end of 2010: the results include measurements of charged-particle pseudorapidity, multiplicity and transverse momentum distributions. Also, the two-pion Bose-Einstein correlation and the measurement of antiproton-to-proton ratio will be discussed. Furthermore, results on the production of identified particles including strange particles will be shown as well as first results from the first Pb--Pb run at the LHC.
