Design, waterproofing, and mass production of the 3-inch PMT frontend system of JUNO
Jilei Xu, Miao He, Cédric Cerna +628
Over 25,600 3-inch photomultiplier tubes (PMTs) have been instrumented for the central detector of the Jiangmen Underground Neutrino Observatory. Each PMT is equipped with a high-v…
Probing leptophobic dark sector with a pseudoscalar portal in the NA64 experiment at CERN
Sergei N. Gninenko, Dmitry V. Kirpichnikov, Nikolai V. Krasnikov +3
We propose the possibility of discovering a light pseudoscalar particle , axion-like particle (ALP), interacting mainly with quarks using the electron and photon scattering reac…
Proof of principle for a light dark matter search with low-energy positron beams at NA64
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54
Thermal light dark matter (LDM) with particle masses in the 1 MeV - 1 GeV range could successfully explain the observed dark matter abundance as a relic from the primordial Univers…
Searching for Light Dark Matter and Dark Sectors with the NA64 experiment at the CERN SPS
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +49
Since its approval in 2016, NA64 has pioneered light dark matter (LDM) searches with electron, positron, muon, and hadron beams. The experiment has successfully met its primary obj…
Formation of true muonium in the Drell-Yan dimuon production
Sergei N. Gninenko, Sergey Kuleshov, Valery E. Lyubovitskij +1
We suggest a new mechanism for the formation of true muonium (), the QED bound state, due to the Coulomb interaction of muons from pairs generated i…
