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

Journal 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 ...

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

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

Dynamical tachyonic AdS/QCD and information entropy
Physics Letters B, 2018 The configurational entropy setup is employed to study dynamical tachyonic holographic AdS/QCD models. The phenomenology of light-flavour mesonic states is then corroborated by the Shannon's information.

Standard Model prediction of the B c lifetime
Journal of High Energy Physics, 2021 Applying an operator product expansion approach we update the Standard Model prediction of the B c lifetime from over 20 years ago. The non-perturbative velocity expansion is carried out up to third order in the relative velocity of the heavy quarks. The

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.

Colour and logarithmic accuracy in final-state parton showers
Journal of High Energy Physics, 2021 Standard dipole parton showers are known to yield incorrect subleading-colour contributions to the leading (double) logarithmic terms for a variety of observables. In this work, concentrating on final-state showers, we present two simple, computationally

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.
