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…

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…

Search for a Hypothetical 16.7 MeV Gauge Boson and Dark Photons in the NA64 Experiment at CERN
D. Banerjee, V. E. Burtsev, A. G. Chumakov +45
We report the first results on a direct search for a new 16.7 MeV boson (X) which could explain the anomalous excess of e+e- pairs observed in the excited Be-8 nucleus decays. Due…
