Advances in High Energy Physics, 2022 In this minireview article, the transverse momentum spectra of final-state particles produced in high-energy hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions described by the multisource thermal model at the quark or parton level are ...

Heavy-flavour jet properties and correlations from small to large systems measured by ALICE [PDF]
EPJ Web of Conferences, 2023 The early production of heavy-flavour partons makes them an excellent probes for investigating the evolution of QCD systems. Jets tagged by the presence of a heavy-flavour hadron give access to the kinematics of the heavy partons and allow for ...

MRST partons generated in a fixed-flavour scheme [PDF]
, 2010 We generate fixed three- and four-light-flavour sets of partons using MRST2004 partons as input. We show that it is important to set nf=3 in the strong coupling, as well as in the splitting and coefficient functions, in order to obtain a consistent set ...

Nuclear Physics B - Proceedings Supplements, 1997 Adapted from talks at XXVIII International Conference on High Energy Physics, Warsaw, July 1996 and at QCD Euroconference 96, Montpellier, July 1996. 13 pages with 11 figures. Figure 5 has some defective postscript code that may confuse ghostview, but it prints correctly.

Polarized 3 parton production in inclusive DIS at small x
Physics Letters B, 2016 Azimuthal angular correlations between produced hadrons/jets in high energy collisions are a sensitive probe of the dynamics of QCD at small x. Here we derive the triple differential cross section for inclusive production of 3 polarized partons in DIS at

Tree-level splitting amplitudes for a gluon into four collinear partons
Journal of High Energy Physics, 2020 We compute in conventional dimensional regularisation the tree-level splitting amplitudes for a gluon parent which splits into four collinear partons. This is part of the universal infrared behaviour of the QCD scattering amplitudes at next-to-next-to ...

Physics Letters B, 1979 Abstract We formulate an evolution equation for the generating functional of parton distributions. It permits a detailed study of the branching process. Several numerical examples are given, and the relevance for jet phenomenology discussed.

Generalized Parton Distributions [PDF]
26th Annual Hampton University Graduate Studies Program, Jefferson Lab, May 30, 2011, 2000 Applications of perturbative QCD to deeply virtual Compton scattering and hard exclusive electroproduction processes require a generalization of the usual parton distributions for the case when long-distance information is accumulated in nondiagonal matrix elements of quark and gluon light-cone operators.

Limiting fragmentation from scale-invariant merging of fast partons [PDF]
, 2008 Exploiting the idea that the fast partons of an energetic projectile can be treated as sources of colour radiation interpreted as wee partons, it is shown that the recently observed property of extended limiting fragmentation implies a scaling law for ...

3 parton production at DIS at small x
EPJ Web of Conferences, 2018 We use the spinor helicity formalism to calculate the cross section for production of three partons of a given polarization in Deep Inelastic Scattering (DIS) off proton and nucleus targets at small Bjorken x. The target proton or nucleus is treated as a
