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 ...

Toy models of Universe with an Effective varying $\Lambda$-Term in Lyra Manifold [PDF]

, 2014
We are interested by the study of several toy models of the Universe in presence of interacting quintessence DE models. Models are considered in the cosmology with an Effective varying $\Lambda$-Term in Lyra Manifold.

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.

Stochastic attractors for shell phenomenological models of turbulence [PDF]

, 2009
Recently, it has been proposed that the Navier-Stokes equations and a relevant linear advection model have the same long-time statistical properties, in particular, they have the same scaling exponents of their structure functions.

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.

Phenomenological study of hadron interaction models [PDF]

, 2001
We present a phenomenological study of three models with different effective degrees of freedom: a Goldstone Boson Exchange (GBE) model which is based on quark-meson couplings, the quark delocalization, color screening model (QDCSM) which is based on ...

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.

Serendipity in dark photon searches

Journal of High Energy Physics, 2018
Searches for dark photons provide serendipitous discovery potential for other types of vector particles. We develop a framework for recasting dark photon searches to obtain constraints on more general theories, which includes a data-driven method for ...

On the impact of dimension-eight SMEFT operators on Higgs measurements

Journal of High Energy Physics, 2019
Using the production of a Higgs boson in association with a W boson as a test case, we assess the impact of dimension-8 operators within the context of the Standard Model Effective Field Theory.
