Journal 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]
Annalen 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
Journal 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.

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

Journal of High Energy Physics, 2023 We present a novel construction for a Higgs-VEV sensitive (HVS) operator, which can be used as a trigger operator in cosmic selection models for the electroweak hierarchy problem.

Light new particles at the kaon experiments
Journal 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
Journal 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

Relativistic free-particle quantization on the light-front: New aspects [PDF]
AIP Conference Proceedings, 2004 We use the light-front machinery to study the behavior of a relativistic free particle and obtain the quantum commutation relations from the classical Poisson brackets. We argue that the usual projection onto the light-front coordinates for these from the covariant commutation ralations does not reproduce the expected results.
