Light gauge boson in rare K decay
We study the production of a light gauge boson in K−→π−X decay, where the associated new charge current is not conserved. It is found that the process can be generated by the tree-level W-boson annihilation and loop-induced s→dX. We find that it strongly depends on the SU(3) limit or the unique gaug...
