Jet observables without jet algorithms
We introduce a new class of event shapes to characterize the jet-like structure of an event. Like traditional event shapes, our observables are infrared/collinear safe and involve a sum over all hadrons in an event, but like a jet clustering algorithm, they incorporate a jet radius parameter and a transverse momentum cut. Three of the ubiquitous jet-based observables — jet multiplicity, summed ...
متن کاملJet-shape Observables
Jet-shape studies provide information on QCD dynamics, are essential tools in analysis of (expected) “new physics” events and are needed for theoretical improvements and tests for Monte Carlo simulations. Jetsshape measurement involves the bulk of the events. They provide 30% of the entries in the determination of αs. Jets are present in all hard events in all high energy processes (ee, DIS and...
متن کاملJet Observables in Hadronic Dijet Production
Hadronic collisions constitute one of the most exciting environments for high energy physicists, both theorists and experimentalists. Due to the large centreof-mass energies that can be reached, they are ideal for the search of new particles. Moreover, they are incredibly rich from the point of view of QCD. In particular, measures of final-state energy flow are important for various aspects. Be...
متن کاملPower counting to better jet observables
Optimized jet substructure observables for identifying boosted topologies will play an essential role in maximizing the physics reach of the Large Hadron Collider. Ideally, the design of discriminating variables would be informed by analytic calculations in perturbative QCD. Unfortunately, explicit calculations are often not feasible due to the complexity of the observables used for discriminat...
متن کاملAutomated resummation of jet observables in QCD
Understanding the physics of event shapes and jet rates (collectively jet observables) requires a deep knowledge of QCD dynamics. Their distributions (defined as the fraction of events Σ(v) with the observable’s value V less than v) explore a wide range of physical scales, from the more inclusive region v = O(1), well described by fixed order perturbative (PT) calculations, to the extreme exclu...
