Parton particle
WebHadrons often manifest themselves as part of a jet, a collimated array of particles generated by parton shower processes from an energetic parton created in high energy particle collisions. The progress in computing and probing the substructure of the jets has opened up new ways to study perturbative as well as non-perturbative aspects of QCD ... WebThe formulae for calculating jet fragmentation momentum, j2T, and parton transverse momentum, k2T, and conditional yield are discussed in the two-particle correlation framework. Additional corrections are derived to account for the limited detector acceptance and inefficiency, for cases when the event mixing technique is used. The validity of our …

Polarization rate for spin-1/2 particles In this note, we apply the result of Ref. [1] to calculate the global polarization in heavy ion collisions and compare it with the STAR data at √ sNN = 200 GeV [5]. We consider all 2-to-2 parton scattering processes A + B → 1 + 2 with at least one quark or anti-quark in the ï¬ nal state.

WebJun 1, 1973 · The parton theory is developed along several lines. We begin by developing quantum mechanics in the infinite momentum frame. The Galilean analogy is worked out and the use of non-relativistic reasoning in relativistic contexts is illustrated. Applications of infinite momentum quantum mechanics include the computation of the radius of a ...
