The Production of Neutral Bilepton Bosons in Proton-Proton Collisions

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 $p+p⟶X^0+X^{0\ast }+anything$, 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.
