  • Dark Matter Search in Missi... Dark Matter Search in Missing Energy Events with NA64
    Banerjee, D.; Burtsev, V. E.; Chumakov, A. G. ... Physical review letters, 09/2019, Letnik: 123, Številka: 12
    Journal Article
    Recenzirano
    Odprti dostop

    A search for sub-GeV dark matter production mediated by a new vector boson A′, called a dark photon, is performed by the NA64 experiment in missing energy events from 100 GeV electron interactions in ...

  • Search for Axionlike and Sc... Search for Axionlike and Scalar Particles with the NA64 Experiment
    Banerjee, D.; Bernhard, J.; Burtsev, V. E. ... Physical review letters, 08/2020, Letnik: 125, Številka: 8
    Journal Article
    Recenzirano
    Odprti dostop

    We carried out a model-independent search for light scalar (s) and pseudoscalar axionlike (a) particles that couple to two photons by using the high-energy CERN SPS H4 electron beam. The new ...

  • Search for a Hypothetical 1... Search for a Hypothetical 16.7 MeV Gauge Boson and Dark Photons in the NA64 Experiment at CERN
    Banerjee, D; Burtsev, V E; Chumakov, A G ... Physical review letters, 06/2018, Letnik: 120, Številka: 23
    Journal Article
    Recenzirano
    Odprti dostop

    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 ^{8}Be^{*} nucleus decays. Because of ...

  • Search for Invisible Decays... Search for Invisible Decays of Sub-GeV Dark Photons in Missing-Energy Events at the CERN SPS
    Banerjee, D; Burtsev, V; Cooke, D ... Physical review letters, 2017-Jan-06, Letnik: 118, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    We report on a direct search for sub-GeV dark photons (A^{'}), which might be produced in the reaction e^{-}Z→e^{-}ZA^{'} via kinetic mixing with photons by 100 GeV electrons incident on an active ...

  • Search for vector mediator ... Search for vector mediator of dark matter production in invisible decay mode
    Banerjee, D.; Burtsev, V. E.; Chumakov, A. G. ... Physical review. D, 04/2018, Letnik: 97, Številka: 7
    Journal Article
    Recenzirano
    Odprti dostop

    A search is performed for a new sub-GeV vector boson (A′) mediated production of dark matter (χ) in the fixed-target experiment, NA64, at the CERN SPS. The A′, called dark photon, can be generated in ...
