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…

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…

Search for vector-boson resonances decaying to a top quark and bottom quark in the lepton plus jets final state in collisions at = 13 TeV with the ATLAS detector

ATLAS Collaboration

A search for new charged massive gauge bosons, , is performed with the ATLAS detector at the LHC. Data were collected in proton-proton collisions at a centre-of-mass ener…

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…
