Heavy Higgs boson production at colliders in the singlet-triplet scotogenic dark matter model

, 2017
We consider the possibility that the dark matter particle is a scalar WIMP messenger associated to neutrino mass generation, made stable by the same symmetry responsible for the radiative origin of neutrino mass.

Production of light dark particles from nonlinear Compton scattering between intense laser and muon or proton beam

Journal of High Energy Physics
The laser of an intense electromagnetic field promotes the studies of strong-field particle physics in high-intensity frontier. Particle accelerator facilities in the world produce high-quality muon and proton beams.

Constraining Asymmetric Dark Matter using colliders and direct detection

Journal of High Energy Physics
We reappraise the viability of asymmetric dark matter (ADM) realized as a Dirac fermion coupling dominantly to the Standard Model fermions. Treating the interactions of such a DM particle with quarks/leptons in an effective-interactions framework, we ...

Search for dark photons at future e$^+$e$^-$ colliders

, 2023
In a class of theories, dark matter is explained by postulating the existence of a 'dark sector',which interacts gravitationally with ordinary matter. If this dark sector contains a U(1) symmetry,and a corresponding 'dark' photon () , it is natural to ...

Vector dark matter from the 5-dimensional representation of SU(2) L

Journal of High Energy Physics
The introduction of electroweak multiplets that transform under any representation of the standard SU(2) L gauge group suggests the existence of electrically neutral stable particles capable of serving as cold dark matter in the ΛCDM cosmological model ...

Pharmacokinetic Assessment of Atazanavir and Favipiravir Following Echinacea Supplementation: A Controlled Herb–Drug Interaction Investigation

Biopharmaceutics &Drug Disposition, EarlyView.
Pharmacokinetic interactions between Echinacea and two antiviral drugs, favipiravir and atazanavir, were assessed in rats. The findings suggest that Echinacea does not significantly affect the pharmacokinetics of favipiravir and atazanavir. These results provide preliminary evidence that concurrent use of Echinacea with these antiviral drugs may be ...

Novel collider signatures in the type-I 2HDM+a model

Journal of High Energy Physics
The 2HDM+a model is one of the main models used in the interpretations of dark matter searches at the LHC. So far, all the 2HDM+a benchmarks considered by the ATLAS and CMS experiments are limited to a type-II Yukawa sector, in which the Higgs bosons A ...

Re‐thinking teachers' professional development: An analysis of National Professional Qualifications for school leaders in England

British Educational Research Journal, EarlyView.
Abstract This article considers how teachers' professional development could be redeveloped to help address the current crisis in teacher recruitment and retention by offering greater intellectual rigour and more opportunities for intellectual growth. Our analysis is focused on the UK government's current policy for leadership development in schools in

Dark fluxes from electromagnetic cascades

Journal of High Energy Physics
We study dark sector production in electromagnetic (EM) cascades. This problem requires accurate simulations of Standard Model (SM) and dark sector processes, both of which impact angular and energy distributions of emitted particles that ultimately ...
