Terrestrial detection of hidden vectors produced by solar nuclear reactions

open access: yesJournal of High Energy Physics, 2023
Solar nuclear reactions can occasionally produce sub-MeV elusive beyond the Standard Model particles that escape the solar interior without further interactions. This study focuses on massive spin-one particles.

Natural Dark Matter from an Unnatural Higgs Boson and New Colored Particles at the TeV Scale [PDF]

open access: yes, 2007
The thermal relic abundance of Dark Matter motivates the existence of new electroweak scale particles, independent of naturalness considerations. However, most unnatural Dark Matter models do not ensure the presence of new particles charged under SU(3)_C,

Probing light mediators and (g − 2) μ through detection of coherent elastic neutrino nucleus scattering at COHERENT

open access: yesJournal of High Energy Physics, 2022
We present the constraints on the parameters of several light boson mediator models obtained from the analysis of the current data of the COHERENT CEνNS experiment. We consider a variety of vector boson mediator models: the so-called universal, the B − L

The quest for axions and other new light particles [PDF]

open access: yesAnnalen der Physik, 2013
Standard Model extensions often predict low‐mass and very weakly interacting particles, such as the axion. A number of small‐scale experiments at the intensity/precision frontier are actively searching for these elusive particles, complementing searches for physics beyond the Standard Model at colliders.

FCNC charmed-hadron decays with invisible singlet particles in light of recent data

open access: yesJournal of High Energy Physics, 2023
The flavor-changing neutral current (FCNC) decays of charmed hadrons with missing energy (Ɇ) can serve as potentially promising hunting grounds for hints of new physics, as the standard-model backgrounds are very suppressed.

Phenomenology of Electroweak Symmetry Breaking from Theory Space [PDF]

open access: yes, 2002
Recently, a new class of realistic models for electroweak symmetry breaking have been constructed, without supersymmetry. These theories have naturally light Higgs bosons and perturbative new physics at the TeV scale.

A search for new light charged particles in photoproduction [PDF]

open access: yesEPJ Web of Conferences, 2019
Motivated by recent V.A. Nikitin’s reports on observation of new light charged particles with a 2-meter JINR propane bubble chamber we perform an experiment at the LPI electron synchrotron "Pakhra" with the aim to detect such particles in the Bethe–Heitler process.

Light new particles at the kaon experiments

open access: yesJournal of Physics: Conference Series, 2023
Abstract Feebly interacting light particles are an attractive addition to the SM because they appear in the broad context of new physics models that address significant issues of the standard model. Searches for the light particles using kaons benefit from their small total decay widths and the availability of enormous datasets. Recently,

FCNC B and K meson decays with light bosonic Dark Matter

open access: yesJournal of High Energy Physics, 2023
We consider decays of B and K mesons into a pseudo-scalar or vector meson plus missing energy. Within the SM, these modes originate from flavor changing neutral current (FCNC) processes with two neutrinos in the final state. In this paper we consider the
