We derive the in-medium gluon radiation spectrum off a quark within path integral formalism at finite energies, including all next-to-eikonal corrections in propagators of quarks and gluons. Results are computed for formation times, interference with vacuum amplitudes. By rewriting medium averages convenient manner we present terms dipole cross sections colour decoherence parameter same physical origin as that found previous studies antenna radiation.

The tiny droplets of quark gluon plasma (QGP) created in high-energy nuclear collisions experience fast expansion and cooling with a lifetime few fm/c. Despite the information provided by probes such as jet quenching quarkonium suppression, excellent description hydrodynamical models, direct access to time evolution system remains elusive. We point out that study hadronically decaying W bosons, notably events top-antitop pair, can provide key novel insight into structure QGP. This is because...

A bstract The modifications imprinted on jets due to their interaction with Quark Gluon Plasma (QGP) are assessed by comparing samples of produced in nucleus-nucleus collisions and proton-proton collisions. standard procedure ignores the effect bin migration specific observables for jet populations at same reconstructed transverse momentum ( p T ). Since is itself modified QGP, all such comparisons confound QGP induced changes that simply a consequence started out differently. quantile...
The study of quantum chromodynamics (QCD) at ultrarelativistic energies can be performed in a controlled environment through lepton-hadron deep inelastic scatterings. In such collisions, the high-energy partonic emissions that follow from ejected hard partons are accurately described by perturbative QCD. However, lower energy scales which quarks and gluons experience color confinement, i.e., hadronization mechanism, fall outside validity regions for calculations, requiring phenomenological...
Energy-energy correlators (EECs) within high energy jets serve as a key experimentally accessible quantity to probe the scale and structure of quark-gluon plasma (QGP) in relativistic heavy-ion collisions. The CMS Collaboration's first measurement modification EEC single inclusive Pb+Pb collisions relative p+p reveals significant enhancement at small angles, which may arise from jet transverse momentum $p_T$ selection biases due loss. We investigate dependence EECs on flavor initiating...
Abstract The lower energy thresholds of large wide-field gamma-ray observatories are often determined by their capability to deal with the very low-energy cosmic ray background. In fact, in areas tens or hundreds thousands square meters, number background events generated superposition random, low rays is huge and may exceed far possible signal events. this article, we argue that a trigger strategy based on pattern recognition shower front can significantly reject background, keeping good...

We consider two different methods, an area-based one implemented through FastJet package pedestal method, that resemble ones by...
