A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Journal of High Energy Physics, 2023 Composite Higgs models with extended symmetries can feature mesonic dark matter candidates. In fundamental CHMs, the origin of dark parity can be explained in the UV theory.

Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi
Advanced Science, EarlyView.Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

A bottom-up approach to fermion mass hierarchy: a case with vector-like fermions
Progress of Theoretical and Experimental Physics, 2020 Abstract We propose a bottom-up approach in which a structure of high-energy physics is explored by accumulating existence proofs and/or no-go theorems in the standard model or its extension. As an illustration, we study fermion mass hierarchies based on an extension of the standard model with vector-like fermions.

Muon g-2 and dark matter in models with vector-like fermions [PDF]
Proceedings of The European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2017), 2018 We investigate simplified models of new physics that can accommodate the measured value of the anomalous magnetic moment of the muon and the relic density of dark matter. We define a set of renormalizable, SU(2)$\times$U(1) invariant extensions of the Standard Model, each comprising an inert $\mathbb{Z}_2$-odd scalar field and one or more vector ...

Vector-like quark doublets, weak-basis invariants and CP violation
Journal of High Energy PhysicsWe study Standard Model extensions with isodoublet vector-like quarks with standard charges. Their presence induces right-handed charged and neutral currents.

Naturally light Dirac and pseudo-Dirac neutrinos from left-right symmetry
Journal of High Energy Physics, 2022 We develop a class of left-right symmetric theories based on the gauge group SU(3) c × SU(2) L × SU(2) R × U(1) with a generalized seesaw mechanism for generating the charged fermion masses.

A renormalizable left-right symmetric model with low scale seesaw mechanisms
Nuclear Physics B, 2022 We propose a low scale renormalizable left-right symmetric theory that successfully explains the observed SM fermion mass hierarchy, the tiny values for the light active neutrino masses and is consistent with the lepton and baryon asymmetries of the ...
