Probing HNL‐ALP Couplings at Colliders
Fortschritte 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.

Pentagon integrals to arbitrary order in the dimensional regulator
Journal of High Energy Physics, 2021 We analytically calculate one-loop five-point Master Integrals, pentagon integrals, with up to one off-shell leg to arbitrary order in the dimensional regulator in d = 4−2𝜖 space-time dimensions.

Advances 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.

Tree-level splitting amplitudes for a gluon into four collinear partons
Journal of High Energy Physics, 2020 We compute in conventional dimensional regularisation the tree-level splitting amplitudes for a gluon parent which splits into four collinear partons. This is part of the universal infrared behaviour of the QCD scattering amplitudes at next-to-next-to ...

Global analysis of the Sivers functions at NLO+NNLL in QCD
Journal of High Energy Physics, 2021 We perform global fit to the quark Sivers function within the transverse momentum dependent (TMD) factorization formalism in QCD. We simultaneously fit Sivers asymmetry data from Semi-Inclusive Deep Inelastic Scattering (SIDIS) at COMPASS, HERMES, and ...

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

Framing energetic top-quark pair production at the LHC
Journal of High Energy Physics, 2021 Top-quark pair production is central to many facets of LHC physics. At leading order, the top and anti-top are produced in a back-to-back topology, however this topology accounts only for a minority of the events with TeV-scale momentum transfer that ...

Generalising Holographic Superconductors
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper we propose a generalised holographic framework to describe superconductors. We first unify the description of s‐, p‐, and d‐wave superconductors in a way that can be easily promoted to higher spin. Using a semianalytical procedure to compute the superconductor properties, we are able to further generalise the geometric description of the ...

Journal of High Energy Physics, 2020 We discuss how to calculate cross sections as well as rapidity, transverse momentum and energy distributions of ντ and ν ¯ τ $$ {\overline{\nu}}_{\tau } $$ produced from the direct D s ± → ν τ / ν ¯ τ $$ {D}_s^{\pm}\to {\nu}_{\tau }/{\overline{\nu}}_ ...

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