Phenomenological studies in the matrix models [PDF]

, 2014
Matrix models are a promising candidate for a nonperturbative formulation of the superstring theory. It is possible to study how the standard model and other phenomenological models appear from the matrix model, and estimate the probability distribution ...

Leptophilic bosons and muon g-2 at lepton colliders

Journal of High Energy Physics, 2021
A light leptophilic boson (scalar or pseudoscalar) has been postulated to explain the muon g-2 anomaly and could be a portal to dark matter. Realizing the leptophilic nature of a singlet boson in the framework of the two-Higgs-doublet-Model of type-X, we

Hidden monopole dark matter via axion portal and its implications for direct detection searches, beam-dump experiments, and the H0 tension

Journal of High Energy Physics, 2020
Hidden monopole is a plausible dark matter candidate due to its stability, but its direct experimental search is extremely difficult due to feeble interactions with the standard model particles in the minimal form.

Systematic Analysis of the Sensor Coverage of Automated Vehicles Using Phenomenological Sensor Models* [PDF]

2019 IEEE Intelligent Vehicles Symposium (IV), 2019
The objective of this paper is to propose a systematic analysis of the sensor coverage of automated vehicles. Due to an unlimited number of possible traffic situations, a selection of scenarios to be tested must be applied in the safety assessment of ...

Unified dark energy models : a phenomenological approach [PDF]

, 2004
A phenomenological approach is proposed to the problem of universe accelerated expansion and of the dark energy nature. A general class of models is introduced whose energy density depends on the redshift $z$ in such a way that a smooth transition among ...

Entangling Higgs production associated with a single top and a top-quark pair in the presence of anomalous top-Yukawa coupling

Journal of High Energy Physics, 2017
The ATLAS and CMS collaborations observed a mild excess in the associated Higgs production with a top-quark pair t t ¯ h $$ \left(t\overline{t}h\right) $$ and reported the signal strengths of μ tth ATLAS  = 1.81 ± 0.80 and μ tth CMS  = 2.75 ± 0.99 based ...

Cornering colored coannihilation

Journal of High Energy Physics, 2018
In thermal dark matter models, allowing the dark matter candidate to coannihilate with another particle can considerably loosen the relic density constraints on the dark matter mass. In particular, introducing a single strongly interacting coannihilation

Higgs Quark Flavor Violation: Simplified Models and Status of General Two-Higgs-Doublet Model

Journal of High Energy Physics, 2020
We study quark flavor violating interactions mediated by the Higgs boson h. We consider observables involving a third generation quark, of both the up and the down quark sectors, like h → bs and t → ch.

Universal relations in composite Higgs models

Journal of High Energy Physics, 2019
We initiate a phenomenological study of “universal relations” in composite Higgs models, which are dictated by nonlinear shift symmetries acting on the 125 GeV Higgs boson.

Dark confinement-deconfinement phase transition: a roadmap from Polyakov loop models to gravitational waves

Journal of High Energy Physics, 2021
We explore the confinement-deconfinement phase transition (PT) of the first order (FO) arising in SU(N) pure Yang-Mills theory, based on Polyakov loop models (PLMs), in light of the induced gravitational wave (GW) spectra.
