    Journal Article

    The transverse momentum spectra of charged particles have been measured in pp and PbPb collisions at by the CMS experiment at the LHC. In the transverse momentum range p T =5–10 GeV/ c , the charged particle yield in the most central PbPb collisions is suppressed by up to a factor of 7 compared to the pp yield scaled by the number of incoherent nucleon–nucleon collisions. At higher p T , this suppression is significantly reduced, approaching roughly a factor of 2 for particles with p T in the range p T =40–100 GeV/ c .
