Search for a leptophobic U(1) B boson using eta->pi0gammagamma and phi->pi0etagamma decays
The possibility for the existence of a leptophobic $U(1)$ gauge boson associated to baryon symmetry is scrutinized in the MeV-GeV mass range by means of an exhaustive analysis of the corresponding golden channels $\eta\to\pi^0\gamma\gamma$ and $\phi\to\pi^0\eta\gamma$. Using the latest experimental data on these two processes and taken also into account the Standard Model contributions from scalar and vector meson exchanges, we are able to obtain the best 95\% exclusion limits up-to-date of the mass $m_B$ and coupling $\alpha_B$ to known particles of this hypothetical $B$ boson.
