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.

Fingerprints of magnetoinduced charge density waves in monolayer graphene beyond half filling
Scientific Reports, 2022 A charge density wave is a condensate of fermions, whose charge density shows a long-range periodic modulation. Such charge density wave can be principally described as a macroscopic quantum state and is known to occur by various formation mechanisms ...

Heavy vector-like quarks decaying to exotic scalars: a case study with triplets
Journal of High Energy PhysicsWe investigate the pair production of a vector-like quark triplet with hypercharge 5/3 decaying into top quark and a complex scalar triplet with hypercharge 1 at the LHC.

Vector boson dark matter from trinification
Journal of High Energy Physics, 2022 We show how trinification models based on the gauge group SU(3) C × SU(3) L × SU(3) R realized near the TeV scale can provide naturally a variety of dark matter (DM) candidates.

Measuring the Hall Effect in Hysteretic Materials
Advanced Materials, EarlyView.The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

R K * $$ {R}_{K^{\left(*\right)}} $$ with leptoquarks and the origin of Yukawa couplings
Journal of High Energy Physics, 2018 We construct a model where the Yukawa couplings of the Standard Model (SM) fermions arise from the breaking of a Z 2 symmetry and through mixing with a fourth family of vector-like fermions.

Proton decay from quark and lepton compositeness
Journal of High Energy Physics, 2022 Within a chiral SU(15) gauge theory in which the Standard Model fermions are bound states of massless preons, we show that proton-decay operators are likely induced at the compositeness scale, Λpre.

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
