Hepatology, EarlyView., 2022 Abstract Background and Aims Reliable noninvasive biomarkers are an unmet clinical need for the diagnosis of NASH. This study investigates the diagnostic accuracy of the circulating triggering receptor expressed on myeloid cells 2 (plasma TREM2) as a biomarker for NASH in patients with NAFLD and elevated liver stiffness.

Uncovering doubly charged scalars with dominant three-body decays using machine learning
Journal of High Energy Physics, 2023 We propose a deep learning-based search strategy for pair production of doubly charged scalars undergoing three-body decays to W + t b ¯ $$ {W}^{+}t\overline{b} $$ in the same-sign lepton plus multi-jet final state. This process is motivated by composite

Boosted displaced decay of right-handed neutrinos at CMS, ATLAS and MATHUSLA
Journal of High Energy Physics, 2023 We investigate boosted displaced signatures in the Type-I seesaw mechanism associated with the B − L gauge symmetry. Such events arise from decays of right-handed neutrinos depending on their Yukawa couplings and masses.

A strongly first-order electroweak phase transition from Loryons
Journal of High Energy Physics, 2022 We study the effect of BSM particles receiving most of their mass from their coupling to the Higgs boson (“Loryons”) on the electroweak phase transition.

Search for exotic leptons in final states with two or three leptons and fat-jets at 13 TeV LHC
Journal of High Energy Physics, 2022 Exotic leptons in large gauge multiplets, appearing in many scenarios beyond the Standard Model (SM), can be produced at the LHC in pairs or association.

Phenomenology and naturalness in gauge extensions of the MSSM after the Higgs discovery [PDF]
, 2016 Supersymmetry remains one of the most favourable candidates for physics beyond the standard model (BSM) due to the solution it provides to the little hierarchy problem as well as the prediction of a Dark matter candidate and other theoretical caveats of ...

Beyond lepton number violation at the HL-LHC: resolving heavy neutrino-antineutrino oscillations
Journal of High Energy Physics, 2023 Collider testable low-scale seesaw models predict pseudo-Dirac heavy neutrinos, that can produce an oscillating pattern of lepton number conserving and lepton number violating events.

Contributions to the muon g − 2 from a three-form field
Journal of High Energy Physics, 2023 We examine contributions to the muon dipole moment g − 2 from a 3-form field Ω, which naturally arises from many fundamental theories, such as the string theory and the hyperunified field theory. In particular, by calculating the one-loop Feynman diagram,

Probing electroweak phase transition in the singlet Standard Model via bbγγ and 4l channels
Journal of High Energy Physics, 2023 We investigate the prospects for resonant di-Higgs and heavy Higgs production searches at the 14 TeV HL-LHC in the combination of bbγγ and 4l channels, as a probe of a possible first order electroweak phase transition in real singlet scalar extension of ...

Systematic study of one-loop realizations of d = 7 long-range 0νββ decay operators
Journal of High Energy Physics, 2023 We study the systematical one-loop decomposition of the dimension-7 long-range 0νββ decay operators. We find that there are 3 genuine one-loop topologies and 8 diagrams.
