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.

Journal of High Energy Physics, 2022 We use the Fitmaker tool to incorporate the recent CDF measurement of m W in a global fit to electroweak, Higgs, and diboson data in the Standard Model Effective Field Theory (SMEFT) including dimension-6 operators at linear order. We find that including

Honeycomb‐Layered Oxides With Silver Atom Bilayers and Emergence of Non‐Abelian SU(2) Interactions
Advanced Science, Volume 10, Issue 6, February 24, 2023., 2023 This work reports a new class of honeycomb‐layered oxides (Ag2 M 2TeO6 (M is a transition or alkaline‐earth metal)) comprising unconventional sub‐valent bilayered silver‐rich domains (Ag6 M 2TeO6), as elucidated via aberration‐corrected transmission electron microscopy.

Lepton-nucleon interactions at the next-to-the-leading order [PDF]
, 2009 Next-to-Leading-Order (NLO) effects play a crucial role in tests of the Standard Model (SM), and require careful theoretical evaluation. Electroweak physics, which has just entered the precision age, is an excellent place to search for new physics, but ...

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.

The Effects of the Widths on the One‐Loop Electroweak Corrections to the pp⟶WW Process
Advances in High Energy Physics, Volume 2023, Issue 1, 2023., 2023 In this paper, we study the effects of the widths of unstable particles on the one‐loop electroweak corrections for the pp⟶WW process at the TeV scale within the framework of the complex mass scheme. We also investigate, for this same process, the unitarity of the theory at high energies.

Probing new physics through entanglement in diboson production
Journal of High Energy Physics, 2023 Pair production of heavy vector bosons is a key process at colliders: it allows to test our understanding of the Standard Model and to explore the existence of new physics through precision measurements of production rates and differential distributions.
