ON PERTURBATIVE QCD OF HARD AND SOFT PROCESSES [PDF]

open access: yesModern Physics Letters A, 2009
We discuss some problems concerning the application of perturbative QCD to high energy processes. In particular for hard processes, we analyze higher order and higher twist corrections. It is argued that these effects are of great importance for understanding the behaviour of pion electromagnetic form factor at moderately large momentum transfers. For

The Gamma Factory: A New Experimental Paradigm for the Post‐HL‐LHC Era

open access: yesAnnalen der Physik, Volume 538, Issue 8, August 2026.
ABSTRACT The Gamma Factory (GF) proposal is motivated by the recognition of a largely untapped potential of the CERN accelerator complex to enable a new research program at the intersection of particle, nuclear, atomic, fundamental, and applied physics. These fields could benefit from novel experimental tools made possible by a future GF facility.

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 ...

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 ...

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.

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 ...

Results and techniques for higher order calculations within the gradient-flow formalism

open access: yesJournal of High Energy Physics, 2019
We describe in detail the implementation of a systematic perturbative approach to observables in the QCD gradient-flow formalism. This includes a collection of all relevant Feynman rules of the five-dimensional field theory and the composite operators ...
