Abstract We examine the properties of ditauonium, an exotic atom consisting of a pair of opposite-sign $$\tau $$ τ leptons bound together by the quantum electrodynamics (QED) interaction in a hydrogen-like state. The energy levels, decay modes and a

Energy evolution of the moments of the hadron distribution in QCD jets including NNLL resummation and NLO running-coupling corrections

Autor: Redamy Pérez-Ramos, David D'Enterria

Publikováno v: Journal of High Energy Physics

The moments of the single inclusive momentum distribution of hadrons in QCD jets, are studied in the next-to-modified-leading-log approximation (NMLLA) including next-to-leading-order (NLO) corrections to the alpha_s strong coupling. The evolution eq
