Light new particles at the kaon experiments [PDF]

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,

A new light particle is being born

Journal of Physics: Conference Series, 2022
AbstractA few years ago we observed anomalous electron-positron angular correlations for the 18.15 MeV M1 transition of8Be. This was interpreted as the creation and decay of an intermediate bosonic particle with a mass ofm0c2=16.70±0.35(stat )±0.5(sys) MeV, which is now called X17.

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.

Nucleon Decays into Light New Particles in Neutrino Detectors [PDF]

Physical Review Letters
Proton and neutron decays into light new particles X can drastically change the experimental signatures and benefit from the complementarity of large water-Cherenkov neutrino detectors such as Super- and Hyper-Kamiokande and tracking detectors such as JUNO and DUNE.

New Light Particle Searches with PADME

Acta Physica Polonica B Proceedings Supplement
The PADME experiment at Laboratori Nationali di Frascati is designed to study possible dark matter explanations relying on the presence of a light particle that acts as a mediator between the visible and the hidden sectors. Three data-taking runs have resulted in the collection of more than \(10^{13}\) positrons-on-target.
