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…
Contribution of exclusive diffractive processes to the measured azimuthal asymmetries in SIDIS
J. Agarwala, M. G. Alexeev, G. D. Alexeev +203
Hadron leptoproduction in Semi-Inclusive measurements of Deep-Inelastic Scattering (SIDIS) on unpolarised nucleons allows one to get information on the intrinsic transverse momentu…
Dark matter search in missing energy events with NA64
D. Banerjee, V. E. Burtsev, A. G. Chumakov +48
A search for sub-GeV dark matter production mediated by a new vector boson , called dark photon, is performed by the NA64 experiment in missing energy events from 100 GeV elect…
Measurement of the cross section for hard exclusive leptoproduction
M. G. Alexeev, G. D. Alexeev, A. Amoroso +199
We report on a measurement of hard exclusive muoproduction on the proton by COMPASS using 160 GeV/ polarised and beams of the CERN SPS impinging on a liquid hy…
