Perturbative QCD at the LHC [PDF]
Il Nuovo Cimento C, 2014 In this brief overview, we discuss selected topics of perturbative QCD at the Large Hadron Collider (LHC). In particular we presents some recent results on parton densities, higher-order calculations, Sudakov resummation and parton ...

Secondary reggeons in perturbative QCD [PDF]
The European Physical Journal C, 2002 Using the Kirschner–Lipatov equation as a basis, we study high energy elastic quark–quark amplitudes, which correspond to secondary reggeons and pion exchange in the double-logarithmic approximation of perturbative ...

Numerical studies of QCD renormalons in high-order perturbative expansions [PDF]
, 2013 Perturbative expansions in four-dimensional non-Abelian gauge theories such as Quantum Chromodynamics (QCD) are expected to be divergent, at best asymptotic. One reason is that it is impossible to strictly exclude from the relevant Feynman diagrams those

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 ...

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

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
