Inclusive hadronic distributions in jets and sub-jets with jet axis from color current
نویسنده
چکیده
The hadronic k ⊥ -spectrum and the gluon to quark average multiplicity ratio r = Ng/Nq inside a high energy sub-jet are determined from a precise definition of the jet axis, including corrections of relative magnitude O(αs) with respect to the Modified Leading Logarithmic Approximation (MLLA), in the limiting spectrum approximation (assuming an infrared cut-off Q0 = Λ QCD ). The results for the k ⊥ -spectrum in the limiting spectrum approximation are found to be, after normalization, in impressive agreement with measurements by the CDF collaboration and the ratio has not been measured yet.

The internal structure of jets produced in pp collisions at the LHC is measured using the ATLAS detector in an inclusive jet sample corresponding to 35 pb−1 of pp collisions at √ s = 7 TeV. Classical jet shape and energy flow measurements are complemented with measurements of new substructure observables with comparisons made to several leading order parton shower Monte Carlo programs. The jet ...
