Additional Baryons and Mesons

TL;DR

This paper discusses theoretical predictions of new baryons and mesons formed by three quarks in a particle physics model, emphasizing their decay properties and the need for higher-energy colliders for experimental study.

Contribution

It introduces a model predicting additional baryons and mesons involving new quarks and analyzes their decay modes, highlighting the experimental challenges at current colliders.

Findings

Predicted new baryons and mesons involving quarks D, S, T.

Decays of these particles are only accessible at colliders with energies around 100 TeV.

Current 14 TeV LHC cannot sufficiently study these particles.

Abstract

In a particle theory model whose most readily discovered new particle is the $\sim 1$TeV bilepton resonance in same-sign leptons, currently being sought at CERN's LHC, there exist three quarks ${\cal D, S, T}$ which will be bound by QCD into baryons and mesons. We consider the decays of these additional baryons and mesons whose detailed experimental study will be beyond the reach of the 14 TeV CERN collider and accessible only at an O(100 TeV) collider.
