Probing scalar, Dirac, Majorana and vector DM through spin-0 electron-specific mediator at the electron fixed-target experiments
I. V. Voronchikhin, D. V. Kirpichnikov
We discuss the thermal target curves of Majorana, Dirac, scalar and vector light dark matter (DM) that are associated with the freeze-out mechanism via the annihilation into $e^+e^…
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…
Probing hidden sectors with a muon beam: implication of spin-0 dark matter mediators for muon anomaly and validity of the Weiszäcker-Williams approach
H. Sieber, D. V. Kirpichnikov, I. V. Voronchikhin +6
In addition to vector () type new particles extensively discussed previously, both CP-even () and CP-odd () spin-0 Dark Matter (DM) mediators can couple to muons and be pr…
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.…
Resonant probing spin-0 and spin-2 dark matter mediators with fixed target experiments
I. V. Voronchikhin, D. V. Kirpichnikov
We discuss the mechanism to produce electron-specific dark matter mediators of spin-0 and spin-2 in the electron fixed target experiments such as NA64 and LDMX. The secondary posit…
