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.

On a Standard Model Extension with Vector-like Fermions and Abelian Symmetry [PDF]

Communications in Physics, 2020
We investigate an extension of the standard model with vector-like fermions and an extra Abelian gauge symmetry. The particle mass spectrum is calculated explicitly. The Lagrangian terms for all the gauge interactions of leptons and quarks in the model are derived.

Gauge-Singlet Vector-Like Fermion Dark Matter, LHC Diphoton Rate, and Direct Detection [PDF]

Advances in High Energy Physics, 2017
We study a gauge-singlet vector-like fermion hidden sector dark matter model, in which the communication between the dark matter and the visible standard model sector is via the Higgs-portal scalar-Higgs mixing and also via a hidden sector scalar with loop-level couplings to two gluons and also to two hypercharge gauge bosons induced by a vector-like ...

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.

Heavy vector-like quarks decaying to exotic scalars: a case study with triplets

Journal of High Energy Physics
We 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.

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.

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

Advanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.
