摘要：

We present a study of the jet transverse structure which could be performed at CMS start up conditions. The analysis corresponds to the first 10pb(-1) of proton-proton collisions at root s = 10 TeV. Jet transverse structure is studied using the second moment of the jet profile in transverse momentum which reflects the distribution of transverse energy inside the jet cone. Different sources of systematics were considered and a comparison of predictions from different generators (HERWIG++ and PYTHIA) was made. The jet structure differs for quark and gluon initiated jets and the possibility of estimating the fractions of quark and gluon jets from the second moment of the jet profile in transverse momentum is discussed.
