Non-global logarithms and jet algorithms in high-pT jet shapes
نویسندگان
چکیده
We consider jet-shape observables of the type proposed recently [1, 2] where the shapes of one or more high-pT jets, produced in a multi-jet event with definite jet multiplicity, may be measured leaving other jets in the event unmeasured. We point out the structure of the full next-to–leading logarithmic resummation specifically including resummation of non-global logarithms in the leading-Nc limit and emphasising their properties. We also point out differences between jet algorithms in the context of soft gluon resummation for such observables.

Jets, Flow, Gaps: Non-global Effects
Perturbation theory (PT) provides the most useful method to study QCD [1]. Although not sufficient to provide a full understanding of QCD, we still miss the comprehension for hadronization, non-perturbative corrections and non convergence of PT expansion, PT study of the general structure of QCD radiation provides most valuable information. Typical example is the study of jet shape observables ...
متن کاملNon - global logarithms in inter - jet energy flow with kt clustering requirement
Recent work in inter-jet energy flow has identified a class of leading logarithms previously not considered in the literature. These so-called non-global logarithms have been shown to have significant numerical impact on gaps-between-jets calculations at the energies of current particle colliders. Here we calculate, at fixed order and to all orders, the effect of applying clustering to the gluo...
متن کاملThe Complete Two-Loop Integrated Jet Thrust Distribution In Soft-Collinear Effective Theory
In this work, we complete the calculation of the soft part of the two-loop integrated jet thrust distribution in e+e− annihilation. This jet mass observable is based on the thrust cone jet algorithm, which involves a veto scale for out–of–jet radiation. The previously uncomputed part of our result depends in a complicated way on the jet cone size, r, and at intermediate stages of the calculatio...
متن کاملJet Quenching
High-pt particles produced in nucleus-nucleus collisions constitute a powerful tool to study the medium properties. The energy loss resulting from the propagation of these particles in the produced medium translates into a suppression of the high-pt yields. These effects are usually associated to medium-induced gluon radiation which, in turn, predicts a broadening of the jet-like signals. Both ...
متن کاملJet shapes with the broadening axis
Broadening is a classic jet observable that probes the transverse momentum structure of jets. Traditionally, broadening has been measured with respect to the thrust axis, which is aligned along the (hemisphere) jet momentum to minimize the vector sum of transverse momentum within a jet. In this paper, we advocate measuring broadening with respect to the “broadening axis”, which is the direction...
