Description
We consider the decay Z → γX where X is a new gauge boson corresponding to an extra U'(1) gauge group factor and find that its partial width can be as large as 5% (the experimental limit for the width of a new decay mode), providing the limit for the X-boson coupling constant: αx'< or approx. 0.1 (Mx/1 GeV)2.
