Improved exclusion limit for light dark matter from $e^{+} e^{-}$ annihilation in NA64

Yu. Andreev, D. Banerjee, J. Bernhard +55

The current most stringent constraints for the existence of sub-GeV dark matter coupling to Standard Model via a massive vector boson $A^{'}$ were set by the NA64 experiment for…

Probing the explanation of the muon (g-2) anomaly and thermal light dark matter with the semi-visible dark photon channel

C. Cazzaniga, P. Odagiu, E. Depero +55

We report the results of a search for a new vector boson ( $A^{'}$ ) decaying into two dark matter particles $χ_{1} χ_{2}$ of different mass. The heavier $χ_{2}$ particle subsequently decays…

Search for pseudoscalar bosons decaying into $e^{+} e^{-}$ pairs in the NA64 experiment at the CERN SPS

Yu. M. Andreev, D. Banerjee, J. Bernhard +52

We report the results of a search for a light pseudoscalar particle $a$ that couples to electrons and decays to $e^{+} e^{-}$ performed using the high-energy CERN SPS H4 electron beam.…
