B boson search at KLOE/KLOE-2
Abstract
Following the many contributions, KLOE-2 has done to Dark Matter (DM) searches, an alternative model, where the Dark Force mediator is a hypothetical leptophobic B boson, in contra-position to the U boson or "dark photon", is investigated. The B boson couples mainly to quarks and it can be searched in the Phi decay to η-B where B will decay in π0-γ. So far, investigation of the π0 -γ invariant mass shows no clear structure belonging to the signal of the DM mediator, hence, an upper limit in the number of events at 90% with CLs the technique will be established for the decay.
