Constructing All-Order Corrections to Multi-Jet Rates [PDF]

, 2009
We discuss the universal behaviour of scattering cross sections in the limit of infinite rapidity separation between all produced particles, and illustrate the behaviour explicitly for the production of n jets, W+n jets, Z+n jets for n=2,3,4, and for H+2,

Sterile neutrino dark matter: impact of active-neutrino opacities

Journal of High Energy Physics, 2020
The resonant production of keV sterile-neutrino dark matter mainly takes place during the QCD epoch of the early universe. It has been argued that it could be strongly affected by the opacities (or damping rates) of active neutrinos, which receive non ...

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect

Advanced Physics Research, Volume 4, Issue 7, July 2025.
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Two loop vertices and tree level multicollinear limits in QCD [PDF]

, 2005
We present a summary of the methods required to solve loop-integrals and their reduction to Master Integrals. We then present the expansion in d = 4 - 2e of the Master Integrals required for the two loop massless vertex diagrams with three off-shell legs.

Quantum‐Classical Simulation of Quantum Field Theory by Quantum Circuit Learning

Annalen der Physik, Volume 537, Issue 6, June 2025.
Quantum circuit learning is employed to simulate quantum field theories (QFTs). By integrating a minimal qubit configuration and low‐depth circuits, the approach predicts real‐time dynamics accurately. It effectively simulates complex phenomena such as quench and chiral dynamics in a model of quantum electrodynamics, aligning well with classical ...

Transition to Perturbative QCD

Journal of Physics: Conference Series, 2011
We review the Jefferson Lab program concerning the interplay between hadronic and underlying quark degrees of freedom in exclusive reactions. Much of the program was initially based on predictions from perturbative QCD (pQCD) concerning scaling of reaction cross sections, helicity conservation, and asymptotic behavior of form factors.

The scale dependence of perturbative QCD predictions for e+e− event shape moments and LHC observables [PDF]

, 2013
Perturbative QCD predictions that are truncated at fixed order have an unphysical dependence on the renormalisation procedure. We investigate two methods of avoiding scale and scheme dependence in QCD predictions of physical observables: the Effective ...

HERWIG 6: an event generator for Hadron emission reactions with interfering gluons (including supersymmetric processes)

, 2000
HERWIG is a general-purpose Monte Carlo event generator, which includes the simulation of hard lepton-lepton, lepton-hadron and hadron-hadron scattering and soft hadron-hadron collisions in one package. It uses the parton-shower approach for initial- and

Prompt neutrinos and intrinsic charm at SHiP

Journal of High Energy Physics, 2019
We present a new evaluation of the far-forward neutrino plus antineutrino flux and number of events from charm hadron decays in a 400 GeV proton beam dump experiment like the Search for Hidden Particles (SHiP).

Visible GeV ALP from TeV Vector‐Like Leptons

Fortschritte der Physik, Volume 73, Issue 3, March 2025.
Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.
