文摘
A new light gauge boson U may have both vector and axial couplings. In a large class of theories, however, the new U(1) current \(J^\mu _F\) naturally combines with the weak neutral current \(J^\mu _{Z_\mathrm{sm}}\), both parity-violating, into a vectorial current \(J^\mu _U\), combination of the \(B,\,L\) and electromagnetic currents with a possible dark-matter current.
