Tree-level splitting amplitudes for a quark into four collinear partons
Journal of High Energy Physics, 2020 We compute in conventional dimensional regularisation the tree-level splitting amplitudes for a quark parent in the limit where four partons become collinear to each other. This is part of the universal infrared behaviour of the QCD scattering amplitudes

Leading-color two-loop amplitudes for four partons and a W boson in QCD [PDF]
Journal of High Energy Physics, 2022 We present the leading-color two-loop QCD corrections for the scattering of four partons and a W boson, including its leptonic decay. The amplitudes are assembled from the planar two-loop helicity amplitudes for four partons and a vector boson decaying ...

Excitation Functions of Tsallis-Like Parameters in High-Energy Nucleus–Nucleus Collisions [PDF]
Entropy, 2021 The transverse momentum spectra of charged pions, kaons, and protons produced at mid-rapidity in central nucleus–nucleus (AA) collisions at high energies are analyzed by considering particles to be created from two participant partons, which are assumed ...

Entanglement negativity of spin-orbit correlations of partons in a general qubit-qudit setup
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy PhysicsWithin a qubit-qudit framework, we studied the negativity as a measure of entanglement for the spin-orbit correlation of partons inside a proton. The entanglement negativity for spin-orbit correlations is found to be related to the gluon helicity PDF ...

On transverse momentum broadening in real-time lattice simulations of the glasma and in the weak-field limit [PDF]
EPJ Web of Conferences, 2022 In these proceedings, we report on our numerical lattice simulations of partons traversing the boost-invariant, non-perturbative glasma as created at the early stages of collisions at RHIC and LHC.

Journal of High Energy Physics, 2020 We consider the double-soft limit of QCD amplitudes with two massive quarks in a back-to-back kinematics accompanied by two soft partons. We integrate analytically the respective double-soft eikonal functions over the phase space of the two soft partons.

Two-loop evolution kernels for colour dependent double parton distributions
Journal of High Energy Physics, 2023 A key ingredient in the description of double parton distributions is their scale dependence. If the colour of each individual parton is summed over, the distributions evolve with the same DGLAP kernels as ordinary parton distributions. This is no longer

Medium response in JEWEL and its impact on jet shape observables in heavy ion collisions
Journal of High Energy Physics, 2017 Realistic modeling of medium-jet interactions in heavy ion collisions is becoming increasingly important to successfully predict jet structure and shape observables.

Nuclear Physics B, 2017 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

Triple (and quadruple) soft-gluon radiation in QCD hard scattering
Journal of High Energy Physics, 2020 We consider the radiation of three soft gluons in a generic process for multi- parton hard scattering in QCD. In the soft limit the corresponding scattering amplitude has a singular behaviour that is factorized and controlled by a colorful soft current ...
