On decays of \(Z^{\prime}\) into unparticle stuff. (English) Zbl 1234.81100

Summary: We study the decay of a \(Z^{\prime}\)-boson into \(U\)-unparticle and a photon. The extended Landau-Yang theorem is used. The clear photon signal would make the decay \(Z^{\prime}\rightarrow \gamma U\) as an additional contribution mode for study of unparticle physics.
