Resumen:
The jet fragmentation function and transverse profile for jets with 25
GeV < ptJet < 500 GeV and etaJet<1.2 produced in proton-proton
collisions with a center-of-mass energy of 7 TeV are presented. The
measurement is performed using data with an integrated luminosity of 36
pb^-1. Jets are reconstructed and their momentum measured using
calorimetric information. The momenta of the charged particle
constituents are measured using the tracking system. The distributions
corrected for detector effects are compared with various Monte Carlo
event generators and generator tunes. Several of these choices show good
agreement with the measured fragmentation function. None of these
choices reproduce both the transverse profile and fragmentation function
over the full kinematic range of the measurement.
