Phenomenological model for the early universe [PDF]
Physical Review D, 2009 We consider the description of cosmological dynamics from the onset of inflation by a perfect fluid whose parameters must be consistent with the strength of the enhanced quantum loop effects that can arise during inflation. The source of these effects must be non-local and a simple incarnation of it is studied both analytically and numerically.

Mono-X versus direct searches: simplified models for dark matter at the LHC
Journal of High Energy Physics, 2017 We consider simplified models for dark matter (DM) at the LHC, focused on mono-Higgs, -Z or -b produced in the final state. Our primary purpose is to study the LHC reach of a relatively complete set of simplified models for these final states, while ...

The evolving self : finding meaning in near-death experiences using interpretative phenomenological analysis. [PDF]
, 2009 Objectives: A variety of anomalous experiences have been reported in the research literature as enhancing, rather than indicating poor mental health. The out-of-body experience (OBE), where the person’s self and body are phenomenologically separate, is a

Exploring properties of long-lived particles in inelastic dark matter models at Belle II
Journal of High Energy Physics, 2021 The inelastic dark matter model is one kind of popular models for the light dark matter (DM) below O(1) GeV. If the mass splitting between DM excited and ground states is small enough, the co-annihilation becomes the dominant channel for thermal relic ...

A Phenomenological Model of Milk Coagulation
Food and raw materials, 2013 A model of additional stabilization for the milk colloid system by means of the micelle electric charge arising owing to dissociation of micellar calcium caseinate is offered. The model allows comprehending the unique role of calcium in milk clotting and describing some features of coagulation temperature dependence, as well as explaining the nature of

The three- and four-Higgs couplings in the general two-Higgs-doublet model
Journal of High Energy Physics, 2018 We apply the unitarity bounds and the bounded-from-below (BFB) bounds to the most general scalar potential of the two-Higgs-doublet model (2HDM). We do this in the Higgs basis, i.e.

Long-lived sterile neutrinos at the LHC in effective field theory
Journal of High Energy Physics, 2021 We study the prospects of a displaced-vertex search of sterile neutrinos at the Large Hadron Collider (LHC) in the framework of the neutrino-extended Standard Model Effective Field Theory (νSMEFT).

Phenomenological modeling of geometric metasurfaces
Optics Express, 2016 Metasurfaces, with their superior capability in manipulating the optical wavefront at the subwavelength scale and low manufacturing complexity, have shown great potential for planar photonics and novel optical devices. However, vector field simulation of metasurfaces is so far limited to periodic-structured metasurfaces containing a small number of ...

Search for the t → ch decay at hadron colliders
Journal of High Energy Physics, 2019 We study the observability for the flavor-changing decay of a top quark t → ch at the Large Hadron Collider (LHC) and future hadron colliders, namely, High-Luminosity LHC (HL-LHC), High-Energy LHC (HE-LHC) and Future Circular hadron-hadron Collider (FCC ...

Two-body lepton-flavour-violating decays in a 2HDM with soft family-lepton-number breaking
Journal of High Energy Physics, 2022 We evaluate the decays ℓ 1 ± $$ {\ell}_1^{\pm } $$ → ℓ 2 ± γ $$ {\ell}_2^{\pm}\gamma $$ , Z → ℓ 1 + ℓ 2 − $$ {\ell}_1^{+}{\ell}_2^{-} $$ , and h → ℓ 1 + ℓ 2 − $$ {\ell}_1^{+}{\ell}_2^{-} $$ , where ℓ 1 and ℓ 2 are charged leptons with different flavours ...
