Limits on 331 vector bosons from LHC proton collision data

Abstract

In this paper, limits are set on bileptons masses and couplings in the context of the the 331 Model, as well as generic, non-331 Models predicting bileptons. The following measurable processes are studied: $pp\to {\ell }^{+}{\ell }^{+}{\ell }^{-}{\ell }^{-}X$, $pp\to {\ell }^{+}{\ell }^{-}\nu \nu X$ and $pp\to {\ell }^{+}{\ell }^{-}X$. Experimental limits on singly-charged bileptons masses and couplings within 331 Models are also obtained for the first time. With the results, an over 20 year-old experimental limit on vector bileptons is increased by 60\%. The computed limits are now the most stringent ones for these particles.
