Which EFT

open access: yesJournal of High Energy Physics, 2019
We classify effective field theory (EFT) deformations of the Standard Model (SM) according to the analyticity property of the Lagrangian as a function of the Higgs doublet H.

Some recent results for SU(3) and octonions within the geometric algebra approach to the fundamental forces of nature

open access: yesMathematical Methods in the Applied Sciences, Volume 47, Issue 3, Page 1471-1491, February 2024.
Different ways of representing the group SU(3)$$ SU(3) $$ within a Geometric Algebra approach are explored. As part of this, we consider characteristic multivectors for SU(3)$$ SU(3) $$ and how these are linked with decomposition of generators into commuting bivectors. The setting for this work is within a 6d Euclidean Clifford Algebra.

Limits on Dark Photons, Scalars, and Axion‐Electromagnetodynamics with the ORGAN Experiment

open access: yesAnnalen der Physik, Volume 536, Issue 1, January 2024.
The nature of dark matter is one of the biggest mysteries in the Universe. ORGAN is an experiment which seeks to understand dark matter by figuring out what it is made of. In this article, the current sensitivity of ORGAN to various promising dark matter candidates is presented, and the future sensitivity is projected.

Measurements of W + W − production cross-sections in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
Measurements of W + W − → e ± νμ ∓ ν production cross-sections are presented, providing a test of the predictions of perturbative quantum chromodynamics and the electroweak theory. The measurements are based on data from pp collisions at s $$ \sqrt{s} $$

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.

Addressing the B-physics anomalies in a fundamental Composite Higgs model

open access: yesJournal of High Energy Physics, 2018
I present a model addressing coherently the naturalness problem of the electroweak scale and the observed pattern of deviations from the Standard Model in semileptonic decays of B mesons.

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.

Relaxation of the chiral imbalance in dense matter of a neutron star

open access: yesEPJ Web of Conferences, 2016
Using the quantum field theory methods, we calculate the helicity flip of an electron scattering off protons in dense matter of a neutron star. The influence of the electroweak interaction between electrons and background nucleons on the helicity flip is

Top Quark Flavor Changing Couplings at a Muon Collider

open access: yesAdvances in High Energy Physics, Volume 2024, Issue 1, 2024.
There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.
