A new detection set-up to search the X17 boson
An excess of electron-positron pairs at large relative angle emitted in the 3 H(p,e + e − ) 4 He, 7 Li(p,e + e − ) 8 Be, and 11 B(p,e + e − ) 12 C nuclear processes has been recently observed. These anomalies are compatible with the creation of a boson with mass of about 17 MeV, not foreseen in the standard model. To probe the possible existence of the so called X17 boson, we propose to study for the first time the 3 He(n,e + e − ) 4 He reaction at the n_TOF facility at CERN. The experimental program and performance of the detector prototype are discussed.
