Measurements of the charm jet cross section and nuclear modification factor in pPb collisions at sNN=5.02 TeV

The CMS Collaboration presents the first measurement of the differential cross section of jets from charm quarks produced in proton–lead (pPb) collisions at a nucleon–nucleon center-of-mass energy of √sNN = 5.02 TeV, as well as results from charm quark jets in proton–proton (pp) collisions at √s =...
