TL;DR: In this paper, the signature of a two-body decay of a particle of mass ∼ 95 GeV/c2 was observed, which fit well with the hypothesis that they are produced by the process p + p → Z 0 + X (with Z 0 → l + + + l − ), where Z 0 is the Intermediate Vector Boson postulated by the electroweak theories as the mediator of weak neutral currents.
