Non-perturbative QCD effects in qT spectra of Drell-Yan and Z-boson production [PDF]
Journal of High Energy Physics, 2014 A bstractThe factorization theorems for transverse momentum distributions of dilepton/boson production, recently formulated by Collins and Echevarria-Idilbi-Scimemi in terms of well-defined transverse momentum dependent distributions (TMDs), allows for a

Can perturbative QCD predict a substantial part of diffractive LHC/SSC physics? [PDF]
, 1992 We examine a model of hadronic diffractive scattering which interpolates between perturbative QCD and non-perturbative fits. We restrict the perturbative QCD resummation to the large transverse momentum region, and use a simple Regge-pole parametrization

S-wave resonance contributions to in the perturbative QCD factorization approach [PDF]
, 2017 By employing the perturbative QCD (PQCD) factorization approach, we study the quasi-two-body decays, where the pion pair comes from the S-wave resonance f0(X).

Abelian Decomposition and Monopole Condensation in QCD
EPJ Web of Conferences, 2018 We demonstrate the monopole condensation in QCD using the Abelian decomposition. The Abelian decomposition decomposes the gluons to the color neutral binding gluons (the neurons and the monopoles) and the colored valence gluons (the chromons), and shows ...

Scalar coupling evolution in a non-perturbative QCD resummation scheme
Physics Letters B, 2015 We compute the Standard Model scalar coupling (λ) evolution in a particular QCD resummation scheme, where the QCD coupling becomes infrared finite due to the presence of a dynamically generated gluon mass, leading to the existence of a non-perturbative ...

One-Loop QCD Corrections to the Thermal Wilson Line Model [PDF]
, 2001 We calculate the time independent four-point function in high temperature (T) QCD and obtain the leading momentum dependent terms. Furthermore, we relate these derivative interactions to derivative terms in a recently proposed finite T effective action ...

Improved estimates of the B-(s) -> VV decays in perturbative QCD approach [PDF]
, 2015 We reexamine the branching fractions, CP asymmetries, and other observables in a large number of B-q -> VV(q = u, d, s) decays in the perturbative QCD approach, where V denotes a light vector meson (rho, K*,omega, phi)The essential difference between ...

Master integrals for two-loop QCD corrections to quark quasi PDFs
Journal of High Energy Physics, 2020 We compute the master integrals for the two-loop QCD corrections to quark quasi parton distribution functions (PDFs) in the large momentum effective theory (LaMET). With a proper canonical basis, we derive the analytical results for the three families of

Soft-drop grooming for hadronic event shapes
Journal of High Energy Physics, 2021 Soft-drop grooming of hadron-collision final states has the potential to significantly reduce the impact of non-perturbative corrections, and in particular the underlying-event contribution.

Heavy-quark fragmentation functions at next-to-leading perturbative QCD [PDF]
, 2016 It is well known that the dominant mechanism to produce hadronic bound states with large transverse momentum is fragmentation. This mechanism is described by the fragmentation functions (FFs) which are the universal and process-independent functions ...
