摘要：
The unparticle effects on production at the future photon collider are investigated. Distributions of t (t) over bar invariant mass and that for transverse momentum of top quark with respect to Standard Model and unparticle production are predicted. An odd valley with scalar unparticle contribution appears for some values of d(u), which is due to the big cancellation between the contribution for SM and that from unparticle. This character may be used to study the properties of scalar unparticle. our investigations also show that scalar unparticle may play a significant role in t (t) over bar production at the photon collider if it exists.
