Vector- and Scalar-Bilepton Pair Production in Hadron Colliders

Understand

We study the double-charged vector-bilepton pair production and double-charged scalar-bilepton pair production {\it via} $p + p \longrightarrow Y^{++} + Y^{--} + X$ and $p + p \longrightarrow S_1^{++} + S_1^{--} + X$, where $Y$ and $S_1$ are vector and scalar bileptons respectively, in the framework of the minimal version of the 3-3-1 model.

• We compute the photon, $Z$, and $Z^\prime$ s-channel contributions for the elementary process of bilepton scalar pair production, and to keep the correct unitarity behavior for the elementary $q \bar q$ interaction, we include the exotic quark t-channel contribution in the vector-bilepton pair production calculation.
• We explore a mass range for $Z^\prime$ and we fix the exotic quark mass within the experimental bounds.
• In this model, the vector-bilepton mass is directly related to $M_{Z^\prime}$ and we consider scalar mass values around the vector-bilepton mass.
