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.

Asymptotically Safe Standard Model via Vector-Like Fermions [PDF]
, 2017 We construct asymptotically safe extensions of the Standard Model by adding gauged vector-like fermions. Using large number-of-flavour techniques we argue that all gauge couplings, including the hypercharge and, under certain conditions, the Higgs ...

Scalar resonance at 750 GeV as composite of heavy vector-like fermions
, 2016 We study a model of scalars which includes both the SM Higgs and a scalar singlet as composites of heavy vector-like fermions. The vector-like fermions are bounded by the super-strong four-fermion interactions.

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.

125 GeV Higgs as a pseudo-Goldstone boson in supersymmetry with vector-like matters
, 2012 We propose a possibility of the 125 GeV Higgs being a pseudo-Goldstone boson in supersymmetry with extra vector-like fermions. Higgs mass is obtained from loops of top quark and vector-like fermions from the global symmetry breaking scale f at around TeV.
