Özet
The decay width of the rare decay Z → ννγ γ is strictly constrained from the LEP data. Tensor unparticles provide a tree-level contribution to this rare decay. We have calculated the tensor unparticle contribution to the rare decay Z → ννγ γ. The current experimental limit has been used to constrain the unparticle couplings ννZUμν and γ γ Uμν. © 2009 THE PHYSICAL SOCIETY OF THE REPUBLIC OF CHINA.
