Large Lorentz Scalar and Vector Potentials in Nuclei [PDF]

open access: yes, 1999
In nonrelativistic models of nuclei, the underlying mass scales of low-energy quantum chromodynamics (QCD) are largely hidden. In contrast, the covariant formulations used in relativistic phenomenology manifest the QCD scales in nuclei through large ...

Analytic results for Sudakov form factors in QCD

open access: yesJournal of High Energy Physics, 2022
Sudakov form factors appear ubiquitously in factorized cross sections where they allow one to resum large logarithms to all orders in perturbation theory.

Positivity bounds on parton distributions at large N_c [PDF]

open access: yes, 2002
Positivity bounds for twist-two parton distributions in multicolored QCD are stronger than their analogs at finite $N_c$. They include the enhanced large $N_{c}$ version of Soffer inequality. These bounds are compatible with the DGLAP evolution to higher

Isotensor Axial Polarizability and Lattice QCD Input for Nuclear Double-β Decay Phenomenology. [PDF]

open access: yesPhysical Review Letters, 2017
The potential importance of short-distance nuclear effects in double-β decay is assessed using a lattice QCD calculation of the nn→pp transition and effective field theory methods.

Standard Model prediction of the B c lifetime

open access: yesJournal of High Energy Physics, 2021
Applying an operator product expansion approach we update the Standard Model prediction of the B c lifetime from over 20 years ago. The non-perturbative velocity expansion is carried out up to third order in the relative velocity of the heavy quarks. The

Gribov's Confinement Scenario [PDF]

open access: yes, 2000
I give a brief account of Gribov's scenario of supercritical charges in QCD. Gribov's equation for the Green function of light quarks and its derivation from the corresponding Dyson-Schwinger equation are described.

QCD phenomenology with infrared finite SDE solutions [PDF]

open access: yes, 2009
Recent progress in the solution of Schwinger-Dyson equations (SDE), as well as lattice simulation of pure glue QCD, indicate that the gluon propagator and coupling constant are infrared (IR) finite. We discuss how this non-perturbative information can be

Colour and logarithmic accuracy in final-state parton showers

open access: yesJournal of High Energy Physics, 2021
Standard dipole parton showers are known to yield incorrect subleading-colour contributions to the leading (double) logarithmic terms for a variety of observables. In this work, concentrating on final-state showers, we present two simple, computationally
