Observation of decay
S. N. Filippov, E. N. Gushchin, A. A. Khudyakov +29
The decay is observed by the OKA collaboration. The branching ratio is measured to be . The branching…
Searches for the light invisible axion-like particle in decay
A. S. Sadovsky, A. P. Filin, S. A. Akimenko +31
A high statistics data sample of the decays is recorded by the OKA collaboration. A missing mass analysis is performed to search for a light invisible pseudoscalar axion-li…
Probing Light Dark Matter with positron beams at NA64
Yu. M. Andreev, A. Antonov, D. Banerjee +63
We present the results of a missing-energy search for Light Dark Matter which has a new interaction with ordinary matter transmitted by a vector boson, called dark photon $A^\prime…
Measurement of the intrinsic hadronic contamination in the NA64 high-purity beam at CERN
Yu. M. Andreev, D. Banerjee, B. Banto Oberhauser +65
In this study, we present the measurement of the intrinsic hadronic contamination at the CERN SPS H4 beamline configured to transport electrons and positrons at 100 GeV/c momentum.…
