Multicomponent dark matter in noncommutative B − L gauge theory

It is shown that for a higher weak isospin symmetry, SU(P)L with P≥3, the baryon minus lepton charge B−L neither commutes nor closes algebraically with SU(P)L similar to the electric charge Q, which all lead to a SU(3)C⊗SU(P)L⊗U(1)X⊗U(1)N gauge completion, where X and N determine Q and B−L, respecti...
