We show that the study of the production of $b \\bar{b}$ pairs at the (upgraded) Tevatron can exclude $\\gamma_B$ with masses ($m_B$) in the range $40 \\lesssim m_B \\lesssim 300$ GeV for $\\gamma_B$ couplings ($\\alpha_B$) greater than $2 \\times 10^{-2}$ ($3 \\times 10^{-3}$). We also show that the HERA experiments cannot improve the present bounds on $\\gamma_B$. Moreover, we demonstrate that the production at HERA and the Tevatron of di--jet events with large rapidity gaps between the jets cannot be explained by the existence of a light $\\gamma_B$.", "revisions": [ { "version": "v1", "updated": "1998-11-16T13:38:22.000Z" } ], "analyses": { "keywords": [ "gauge boson", "baryon number", "collider experiments", "large rapidity gaps", "production" ], "tags": [ "journal article" ], "note": { "typesetting": "RevTeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "inspire": 479352 } } }
