Hunting for Bileptons at Hadron Colliders.

Area of Science:

• High Energy Physics
• Particle Physics
• Beyond Standard Model Physics

Background:

• Bileptons, particles with lepton number L=±2, are predicted by extended gauge symmetries like the 331 model.
• The 331 model, based on SU(3)c×SU(3)L×U(1)X, offers a framework for new particles, including vector and scalar bileptons.

Purpose of the Study:

• To review and analyze potential signals of bileptons at hadron colliders.
• To investigate both leptonic and non-leptonic decay modes of bileptons.
• To assess the sensitivity of current and future hadron colliders to these signals.

Main Methods:

• Theoretical review of bilepton production and decay mechanisms within a specific 331 model variant.
• Analysis of signature characteristics, such as same-sign dilepton pairs and heavy quark final states.
• Exploration of collider sensitivity for detecting these predicted phenomena.

Main Results:

• Bileptons are primarily produced in pairs at hadron colliders, leading to same-sign dilepton signatures.
• Non-leptonic decays involving exotic quarks (charged 4/3 or 5/3) are also possible.
• The study evaluates the detectability of these signals at existing and upcoming colliders.

Conclusions:

• Bilepton searches at hadron colliders are feasible through analysis of specific leptonic and non-leptonic decay channels.
• The 331 model provides a theoretical basis for these new particles and their observable signatures.
• Future collider experiments hold potential for discovering these predicted bilepton signals.
