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…
Spin Density Matrix Elements in Exclusive Meson Muoproduction
M. G. Alexeev, G. D. Alexeev, A. Amoroso +197
We report on a measurement of Spin Density Matrix Elements (SDMEs) in hard exclusive meson muoproduction on the proton at COMPASS using 160 GeV/ polarised and $ μ^{…
Search for heavy neutral lepton production in decays to positrons
NA62 collaboration
A search for heavy neutral lepton () production in decays using the data sample collected by the NA62 experiment at CERN in 2017--2018 is reported. Upper limits of…
Triangle Singularity as the Origin of the
G. D. Alexeev, M. G. Alexeev, A. Amoroso +194
The COMPASS experiment recently discovered a new isovector resonance-like signal with axial-vector quantum numbers, the , decaying to . With a mass too close…
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…
