Electroweak Sudakov corrections for processes at a future Muon Collider [PDF]

open access: yes, 2023
Precision calculations are crucial for the validation or falsification of our understanding of fundamental interactions at colliders. One relevant aspect for present and future colliders is the impact of effects coming from electroweak (EW) corrections.

Primer on Axion Physics

open access: yesAnnalen der Physik, Volume 536, Issue 1, January 2024.
A primer on axion physics, emphasizing an intuitive understanding of why the axion solves the strong CP problem. Abstract The canonical axion potential is reviewed, with an emphasis on the field theory underlying radial and angular modes of complex scalar fields.

Higgs‐induced screening mechanisms in scalar‐tensor theories

open access: yesAnnals of the New York Academy of Sciences, Volume 1531, Issue 1, Page 95-103, January 2024.
Abstract We consider the theory of a light conformally coupled scalar field, that is, one that is coupled directly to the Ricci scalar of the gravitational sector. This theory can be written equivalently as one of a light scalar that is coupled to the Standard Model of particle physics with a particular combination of Higgs‐portal couplings.

Massive two-loop four-point Feynman integrals at high energies with AsyInt

open access: yesJournal of High Energy Physics
We present analytic techniques for parametric integrations of massive two-loop four-point Feynman integrals at high energies, and their implementation in the toolbox AsyInt. In the high-energy region, the Feynman integrals involving external and internal

Electroweak renormalization based on gauge-invariant vacuum expectation values of non-linear Higgs representations: 2. extended Higgs sectors

open access: yes, 2022
A recently proposed scheme for a gauge-invariant treatment of tadpole corrections in spontaneously broken gauge theories - called Gauge-Invariant Vacuum expectation value Scheme (GIVS) - is applied to a singlet Higgs extension of the Standard Model and ...

Non-leptonic B-decays in and beyond QCD factorisation [PDF]

open access: yes, 2005
This thesis examines the non-leptonic B-decays within QCD factorization and beyond, to challenge the assumptions and limitations of the method. We analyse the treatment of the distribution amplitudes of light mesons and present a new model described by ...

Higher order QCD predictions for associated Higgs production with anomalous couplings to gauge bosons

open access: yes, 2016
We present predictions for the associated production of a Higgs boson at NLO+PS accuracy, including the effect of anomalous interactions between the Higgs and gauge bosons.

NLO corrections to triple vector-boson production in final states with three charged leptons and two jets

open access: yesJournal of High Energy Physics
Tri-boson production together with vector-boson scattering is a privileged channel to study the electroweak structure of the Standard Model. Upcoming LHC running stages will allow to measure these processes at unprecedented accuracy and for all possible ...

Incorporation of QCD effects in basic corrections of the electroweak theory

open access: yes, 1993
We study the incorporation of QCD effects in the basic electroweak corrections \drcar, \drcarw, and \dr. They include perturbative \Ord{\alpha\alpha_s} contributions and $t\bar{t}$ threshold effects.

Dimensional reduction in the study of the electroweak phase transition [PDF]

open access: yes, 2018
First-order phase transitions in the electroweak sector are an active subject of research as they contain ingredients for baryon number violation and gravitational-wave production.
