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.

Light by light scattering at high energy: a tool to reveal new particles [PDF]

Physics Letters B, 1999
We point out a few remarkable properties of the $γγ\toγγ$ process at high energy. They should allow to search for effects of new particles and interactions. We give illustrations with threshold effects due to pairs of new charged particles (charginos, charged Higgses, sfermions), resonance effects due to s-channel production of neutral scalars ...

New constraint on dark photon at T2K off-axis near detector

Journal of High Energy Physics, 2023
The T2K experiment is one of the most powerful long-baseline experiments to investigate neutrino oscillations. The off-axis near detector called ND280 is installed 280 m downstream from the neutrino production target to measure the neutrino energy ...

Displaced searches for light vector bosons at Belle II

Journal of High Energy Physics, 2022
With a design luminosity of 50 ab −1 and detectors with tracking capabilities extending beyond 1 m, the Belle II experiment is the perfect laboratory for the search of particles that couple weakly to the Standard Model and have a characteristic decay ...

Resolving the muon g − 2 tension through Z′-induced modifications to σ had

Journal of High Energy Physics, 2023
The QED hadronic vacuum polarization function plays an important role in the determination of precision electroweak observables and of the anomalous magnetic moment of the muon.

Axial vectors in DarkCast

Journal of High Energy Physics, 2022
In this work, we explore new spin-1 states with axial couplings to the standard model fermions. We develop a data-driven method to estimate their hadronic decay rates based on data from τ decays and using SU(3)flavor symmetry.
