Long-Lived Heavy Quarks: A Review

Table 5

𝑄𝑞 (𝑄𝑞) mesons and 𝑄𝑞𝑞 (𝑄𝑞𝑞) (anti-)baryons involving 𝑄=𝑋_5/3, 𝑇_2/3, 𝐵_−1/3, and 𝑌_−4/3 vector-like quarks. The states in bold font are hadrons of which yields are expected to be substantial at the LHC, as predicted in [25] for penetration depths between 0 and 3 meters. For simplicity, only the neutral and positively charged hadrons are displayed.
