Large effects from small QCD instantons: making soft bombs at hadron colliders

open access: yesJournal of High Energy Physics, 2020
It is a common belief that the last missing piece of the Standard Model of particles physics was found with the discovery of the Higgs boson at the Large Hadron Collider.

The Low‐Scale Seesaw Solution to the MW$M_W$ and (g−2)μ$(g-2)_\umu$ Anomalies

open access: yesFortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023
Abstract The recent CDF‐II measurement of the W‐boson mass shows a strong tension with the corresponding Standard Model prediction. Once active neutrino masses are explained in the context of the Low‐Scale Seesaw mechanisms, this tension can be resolved.

Analytic results for Sudakov form factors in QCD

open access: yesJournal of High Energy Physics, 2022
Sudakov form factors appear ubiquitously in factorized cross sections where they allow one to resum large logarithms to all orders in perturbation theory.

Probing HNL‐ALP Couplings at Colliders

open access: yesFortschritte der Physik, Volume 71, Issue 4-5, May 2023., 2023
Abstract Axion‐like particles (ALPs) and heavy neutral leptons (HNLs) are both well‐motivated extensions of the Standard Model. As ALPs couple to on‐shell fermions proportionally to their masses, processes involving both types of particles may give rise, for TeV HNLs, to relevant phenomenology at colliders.

Infrared structure of SU(N) × U(1) gauge theory to three loops

open access: yesJournal of High Energy Physics, 2020
We study the infrared (IR) structure of SU(N ) × U(1) (QCD × QED) gauge theory with n f quarks and n l leptons within the framework of perturbation theory.

Stability of the Next‐to‐Tribimaximal Mixings under Radiative Corrections with the Variation of the SUSY Breaking Scale in MSSM

open access: yesAdvances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023
We analyze the radiative stability of the next‐to‐tribimaximal mixings (NTBM) with the variation of the SUSY breaking scale (mS) in MSSM, for both normal ordering (NO) and inverted ordering (IO) at the fixed input value of the seesaw scale MR = 1015 GeV and two different values of tanβ.

On some short-distance properties of the fourth-rank hadronic vacuum polarization tensor and the anomalous magnetic moment of the muon

open access: yesJournal of High Energy Physics, 2020
Some short-distance properties of the fourth-rank hadronic vacuum polarization tensor are re-examined. Their consequences are critically discussed in the context of the hadronic light-by-light scattering contribution to the anomalous magnetic moment of ...

Sex is a defining feature of neuroimaging phenotypes in major brain disorders

open access: yesHuman Brain Mapping, Volume 43, Issue 1, Page 500-542, January 2022., 2022
Here, we review the human neuroimaging literature examining sex effects on adult brain structure using structural and diffusion MRI. We discuss normative sex differences based on population‐based studies as well as sex differences in 14 major brain diseases.

Tree-level splitting amplitudes for a quark into four collinear partons

open access: yesJournal of High Energy Physics, 2020
We compute in conventional dimensional regularisation the tree-level splitting amplitudes for a quark parent in the limit where four partons become collinear to each other. This is part of the universal infrared behaviour of the QCD scattering amplitudes
