Vector-like fermion and standard Higgs production at hadron colliders [PDF]
Nuclear Physics B, 1990 Vector-like fermions are characterized by large neutral current decay rates, in particular into Higgs bosons. If they exist, their clear signals at hadron colliders open a window to Higgs detection, especially to the intermediate Higgs mass region. We discuss in some detail rates and signatures for simple cases.

W boson mass anomaly and grand unification
Physics Letters B, 2022 It is known that the recently reported shift of the W boson mass can be easily explained by an SU(2)L triplet Higgs boson with a zero hypercharge if it obtains a vacuum expectation value (VEV) of O(1) GeV.

Modelling vector-like quarks in partial compositeness framework
Journal of High Energy Physics, 2022 Composite Higgs models, together with partial compositeness, predict the existence of new scalars and vector-like quarks (partners) at and above the TeV scale.

On the implications of positive W mass shift
Journal of High Energy Physics, 2022 We investigate the phenomenological implications of the recent W mass measurement by the CDF collaboration, which exhibits tension with the standard model (SM) electroweak fit.

Dynamic radius jet clustering algorithm
Journal of High Energy Physics, 2023 The study of standard QCD jets produced along with fat jets, which may appear as a result of the decay of a heavy particle, has become an essential part of collider studies.

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 ...

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.
