Recent advances in the search for a leptopohobic boson at GlueX

A compelling dark-force scenario introduces a new U(1)$_{B}$ gauge symmetry coupling to baryon number. A search for a leptophobic boson has been performed at GlueX in its main decay channels taking advantage of the direct photoproduction mechanism. A bump hunt strategy has been extended to cover a wide unexplored region of the ($M_{B}$,$\alpha_{B}$) plane where all previous experiments could not set limits. The data collected at GlueX provided a significant contribution to this search, which also motivates other similar BSM searches at Jefferson Lab.
