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 ...

Soft integrals and soft anomalous dimensions at N3LO and beyond
Journal of High Energy Physics, 2022 We calculate soft phase-space and loop master integrals for the computation of color-singlet cross sections through N3LO in perturbative QCD. Our results are functions of homogeneous transcendental weight and include the first nine terms in the expansion

Mirror QCD and Cosmological Constant
Universe, 2017 An analog of Quantum Chromo Dynamics (QCD) sector known as mirror QCD (mQCD) can affect the cosmological evolution due to a non-trivial contribution to the Cosmological Constant analogous to that induced by the ground state in non-perturbative QCD.

The Odderon in QCD with running coupling
Journal of High Energy Physics, 2020 Starting from the leading Odderon solution of the three gluon system in perturbative QCD we introduce, as a first step towards the transition to the non-perturbative region, an infrared cutoff and use the running QCD coupling constant.

Precise QCD description of the Higgs boson transverse momentum spectrum
Physics Letters B, 2019 The transverse momentum (pT) distribution of Higgs bosons at hadron colliders enables a detailed probe of its production dynamics and is a key ingredient to precision studies of Higgs boson properties, but receives very large QCD corrections. We obtain a

Experimental Tests Of Perturbative QCD [PDF]
Annual Review of Nuclear and Particle Science, 1989 The main experimental results to test quantum chromodynamics are reviewed. A wide variety of observables related to hard processes are correctly predicted by the theory, thus it is fair to say that the experimental support of QCD is quite solid and quantitative.(AIP)

AN ANALYTIC APPROACH TO PERTURBATIVE QCD [PDF]
International Journal of Modern Physics A, 2000 The two-loop invariant (running) coupling of QCD is written in terms of the Lambert W function. The analyticity structure of the coupling in the complex Q2-plane is established. The corresponding analytic coupling is reconstructed via a dispersion relation.
