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.

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 ...

Searching for BSM neutrino interactions in dark matter detectors [PDF]
, 2019 Neutrino interactions beyond the Standard Model (BSM) are theoretically well motivated and have an important impact on the future precision measurement of neutrino oscillation. In this work, we study the sensitivity of a multi-ton-scale liquid Xenon dark

Maternal Hyperglycemia Disrupts Cerebral Cortex Development Through the Foxp1‐Dll1‐Notch Axis
Advanced Science, EarlyView.Maternal hyperglycemia disrupts offspring cortical development through a Foxp1–Dll1–Notch signaling axis. In a PGDM mouse model, intrauterine hyperglycemia decreases cortical thickness and perturbs neuronal layering by downregulating Foxp1, which transcriptionally regulates the Notch ligand Dll1.

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.
