An Analysis of a Minimal Vectorlike Extension of the Standard Model

Table 1

Quantum numbers of the lightest (pseudo)scalar H-hadrons and the corresponding H-quark currents in model. denotes hyper-G-parity of a state (see Section 4). is the H-baryon number. is the electric charge. is the weak isospin. Hyperbaryons do not carry intrinsic - and -parities, since the charge conjugation reverses the sign of the H-baryon number.
