The high-energy limit of perturbative QCD: Theory and phenomenology

open access: yes, 2022
After a brief introduction of formal and phenomenological progresses in the study of the high-energy limit of perturbative QCD, we present arguments supporting the statement that the inclusive emission of Higgs bosons or heavy-flavored hadrons acts as ...

Connecting the hadron mass scale to the fundamental mass scale of quantum chromodynamics

open access: yesPhysics Letters B, 2015
Establishing an explicit connection between the long distance physics of confinement and the dynamical interactions of quarks and gluons at short distances has been a long-sought goal of quantum chromodynamics.

RECENT DEVELOPMENTS IN PERTURBATIVE QCD [PDF]

open access: yesDeep Inelastic Scattering DIS 2006, 2007
A brief overview of some recently active topics in perturbative QCD, including: string-inspired recursion techniques at tree level; recursion approaches and automation of standard techniques for 1-loop calculations; the status of NNLO jet calculations; and non-trivial structures that appear in higher-order calculations.

Non-perturbative to perturbative QCD via the FFBRST

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Recently a new type of quadratic gauge was introduced in QCD in which the degrees of freedom are suggestive of a phase of abelian dominance. In its simplest form it is also free of Gribov ambiguity.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Sudakov safety in perturbative QCD

open access: yesPhysical Review D, 2015
Traditional calculations in perturbative quantum chromodynamics (pQCD) are based on an order-by-order expansion in the strong coupling $α_s$. Observables that are calculable in this way are known as "safe". Recently, a class of unsafe observables was discovered that do not have a valid $α_s$ expansion but are nevertheless calculable in pQCD using all ...

Infrared behaviour and renormalization scheme invariance of QCD observables [PDF]

open access: yes, 2006
In this thesis we study the infrared (IR) behaviour of QCD observables, and solutions to the problem of renormalization scheme dependence. We investigate the IR behaviour of all-orders leading-b renormalon resummations for certain Euclidean observables ...

Perturbative and non-perturbative interactions between heavy quarks and quark-gluon plasma within a unified approach

open access: yesPhysics Letters B, 2023
While perturbative QCD is sufficient for understanding the color, mass and energy dependences of parton energy loss and jet quenching at large transverse momentum in heavy-ion collisions, a simultaneous description of heavy flavor nuclear modification ...

Describing the Global Gravity Field of Mars With Lithospheric Flexure and Deep Mantle Flow

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The volcanic complex Tharsis Region on Mars is known for its numerous volcanoes on top of the crust, elevated topography (doming), and a long‐wavelength gravity anomaly correlated with the region. Flexural modeling of the lithosphere has commonly been used to understand the relationship between observed topography, crustal structure, and ...
