Abstract
In this paper, limits are set on $Z^\prime$, doubly-charged and singly-charged bileptons masses in the context of the the 331 model. The following measurable processes are studied: $pp \rightarrow \ell^{+}\ell^{+}\ell^{-}\ell^{-}X$, $pp \rightarrow \ell^{+}\ell^{-} \nu \nu X$ and $pp \rightarrow \ell^{+}\ell^{-} X$.
Experimental limits on singly-charged bileptons within 331 models obtained for the first time. The mass lower bounds obtained are 3.7 TeV for $Z^\prime_{331}$, 1.2 TeV for doubly-charged bileptons and 850 GeV for singly-charged bileptons. The computed limits are now the most stringent ones for these particles.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating very compact bibliographies which can be beneficial to authors and readers, and in "proceeding" format which is more detailed and complete.
