Constraints on New Physics in the Electron g-2 from a Search for Invisible Decays of a Scalar, Pseudoscalar, Vector, and Axial Vector
Yu. M. Andreev, D. Banerjee, J. Bernhard +49
We performed a search for a new generic boson, which could be a scalar (), pseudoscalar (), vector () or an axial vector () particle produced in the 100 GeV electro…
Study of decay with OKA setup
A. Yu. Polyarush, V. A. Duk, S. N. Filippov +34
Results of a study of the decay at OKA setup are presented. More than 32000 events of this decay are observed. The differential spectra over the ph…
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…
Stability study and time resolution measurement of Straw Tube detectors
S. Roy, S. Jaiswal, S. Chatterjee +8
Straw tube detectors are single wire proportional counters that are widely used as a tracking device. We have carried out RD with a straw tube detector prototype. The motivatio…
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…
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…
