Improved exclusion limit for light dark matter from 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 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 () decaying into two dark matter particles of different mass. The heavier particle subsequently decays…
Search for pseudoscalar bosons decaying into 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 that couples to electrons and decays to performed using the high-energy CERN SPS H4 electron beam.…
Constraints on New Physics in the Electron g-2 from a Search for Invisible Decays of a Scalar, Pseudoscalar, Vector, and Axial Vector
Yu. M. Andreev, D. Banerjee, J. Bernhard +49
We performed a search for a new generic boson, which could be a scalar (), pseudoscalar (), vector () or an axial vector () particle produced in the 100 GeV electro…
Hunting down the X17 boson at the CERN SPS
E. Depero, Yu. M. Andreev, D. Banerjee +53
Recently, the ATOMKI experiment has reported new evidence for the excess of events with a mass 17 MeV in the nuclear transitions of He, that they previously obs…
Improved limits on a hypothetical X(16.7) boson and a dark photon decaying into pairs
D. Banerjee, J. Bernhard, V. E. Burtsev +51
The improved results on a direct search for a new X(16.7 MeV) boson which could explain the anomalous excess of pairs observed in the excited 8Be nucleus decays ("Berilliu…
