50 GeV $π^{-}$ in, nothing out: a sensitive probe of invisible $η$ and $η^{'}$ decays with NA64h

Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54

We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar $η$ and $η^{'}$ mesons in the NA64h experiment at the CERN SPS. Our n…

Trigger efficiencies of a proposed beam monitoring detector (BeBe) for p+p collisions at NICA energies

Marco Alberto Ayala-Torres, Lucina Gabriela Espinoza Beltrán, Luis A. Hernández-Cruz +3

The Multipurpose Detector (MPD) consists of a typical array of sub-detectors to study the nuclear matter originating from the collisions of beams provided by the Nuclotron-based Io…
