Sensitivity of MAGIX@MESA to BSM effects via Bethe-Heitler pair production
Aleksandr Pustyntsev, Marc Vanderhaeghen
We explore the sensitivity of the upcoming MAGIX experiment at the MESA facility to light Beyond the Standard Model (BSM) mediators in the few to hundred MeV mass range. Utilizing…
New Physics Searches via Beam Normal Spin Asymmetry in Bhabha Scattering
Aleksandr Pustyntsev, Muthubharathi S. Ramasamy, Marc Vanderhaeghen
We examine the sensitivity of the beam normal spin asymmetry in Bhabha scattering to beyond the Standard Model (BSM) mediators, in the context of the JLab polarized positron progra…
Implications of recent measurements for MeV-GeV dark sector searches
Aleksandr Pustyntsev, Marc Vanderhaeghen
Recent theoretical and experimental studies of the muon magnetic moment indicate the absence of the previously reported discrepancy, providing a vital opportunity to constrain pote…
Constraints for scalars and pseudoscalars from and existing colliders
Aleksandr Pustyntsev, Marc Vanderhaeghen
Scalars and pseudoscalars with masses in the MeV to GeV range are of interest in different extensions of the Standard Model. Such particles are often associated with dark matter, t…
