Measurement of charged particle image at high image in PbPb collisions at image with CMS

Charged particle transverse momentum image spectra have been measured by CMS for pp and PbPb collisions at the same image collision energy per nucleon pairs. Calorimeter-based jet triggers are employed to enhance the statistical reach of the high-image measurements. The nuclear modification factor image is obtained in bins of collision centrality for the PbPb data sample dividing by the measured pp reference spectrum. In the range image, the charged particle yield in the most central PbPb collisions is suppressed by up to a factor of 7. At higher image, this suppression is significantly reduced, approaching a factor of 2 for particles with image.
