The Production of Neutral Bilepton Bosons in Proton-Proton Collisions

TL;DR

This paper investigates the production of neutral bilepton bosons in proton-proton collisions at the LHC, identifying signatures and distributions that could confirm their existence as predicted by the 3-3-1 model with right-handed neutrinos.

Contribution

It provides the first detailed analysis of neutral bilepton production signatures at the LHC within the 3-3-1 model framework, including specific process contributions and distribution predictions.

Findings

LHC can produce detectable signals of the $X^0$ bilepton.

Main production channels involve $s$-channel $Z$ and $Z'$ exchanges.

Distinct distributions suggest clear experimental signatures.

Abstract

We establish some signatures of the extra bilepton boson ${X^0}$ predicted in the ${SU (3)_C \times SU (3)_L \times U (1)_X}$ model with right-handed neutrinos. We analyze the process $p + p \longrightarrow X^0 +X^{0*} + {\hbox {anything}}$, for center of mass energy regime of the Large Hadron Collider. The main contributions for the neutral bilepton production in $q \bar q$ process come from the $s-$channel ($Z$ and $Z^\prime$ exchanges), when the initial quarks have charge 2/3, and from an additional $t-$channel (heavy quark exchange) when they have -1/3 of the positron electric charge. We calculate some distributions of the final bileptons and from these results we conclude that LHC can show a clear signature for the existence of the $X^0$ predicted in the 3-3-1 model.
