Extending Precision Perturbative QCD with Track Functions. [PDF]
Physical Review Letters, 2021 Collider experiments often exploit information about the quantum numbers of final state hadrons to maximize their sensitivity, with applications ranging from the use of tracking information (electric charge) for precision jet substructure measurements ...

Non-perturbative phenomena in jet modification [PDF]
EPJ Web of Conferences, 2022 The interaction of a jet with the medium created in heavy-ion collisions is not yet fully understood from a QCD perspective. This is mainly due to the non-perturbative nature of this interaction which affects both transverse jet momentum broadening and ...

Prompt atmospheric neutrino fluxes: perturbative QCD models and nuclear effects [PDF]
Journal of High Energy Physics, 2016 A bstractWe evaluate the prompt atmospheric neutrino flux at high energies using three different frameworks for calculating the heavy quark production cross section in QCD: NLO perturbative QCD, kT factorization including low-x resummation, and the ...

Quantum kinetic theory of spin polarization of massive quarks in perturbative QCD: Leading log [PDF]
Physical Review D, 2019 We present the quantum kinetic equation for spin polarization of massive quarks in leading log order of perturbative QCD, which describes time evolution of the spin density matrix in momentum space of a massive quark interacting with a background QCD ...

Determination of $$\alpha _{S}$$ α S beyond NNLO using event shape averages
European Physical Journal C: Particles and Fields, 2021 We consider a method for determining the QCD strong coupling constant using fits of perturbative predictions for event shape averages to data collected at the LEP, PETRA, PEP and TRISTAN colliders.

Z-Boson Production in Association with a Jet at Next-To-Next-To-Leading Order in Perturbative QCD. [PDF]
Physical Review Letters, 2015 We present the first complete calculation of Z-boson production in association with a jet in hadronic collisions through next-to-next-to-leading order in perturbative QCD.

Heavy-quark effects on cold quark matter and self-bound stars [PDF]
EPJ Web of Conferences, 2022 The heavy-quark effects on the equation of state for cold and dense quark matter are obtained from perturbative QCD, yielding observables parametrized only by the renormalization scale.

Quark beam function at next-to-next-to-next-to-leading order in perturbative QCD in the generalized large- Nc approximation [PDF]
Physical Review D, 2019 We present the matching coefficient for the quark beam function at next-to-next-to-next-to-leading order in perturbative QCD in the generalized large Nc-approximation, Nc ∼ Nf ≫ 1.

Extending the predictive power of perturbative QCD [PDF]
The European Physical Journal C, 2018 The predictive power of perturbative QCD (pQCD) depends on two important issues: (1) how to eliminate the renormalization scheme-and-scale ambiguities at fixed order, and (2) how to reliably estimate the contributions of unknown higher-order terms using ...

Energy Loss in Perturbative QCD [PDF]
Annual Review of Nuclear and Particle Science, 2000 ▪ Abstract We review the propagation of energetic partons in hot or cold QCD matter, as known from recent work. We summarize advances in the understanding of both collisional and radiative energy loss. Our emphasis is on radiative energy loss, which has very interesting properties that may help to detect the quark-gluon plasma produced in heavy-ion ...
