摘要

The unparticle effects on tt production at the future photon collider are investigated.Distributions of ttinvariant 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 du, which is due to the big cancellation between the contribution from 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 tt production at the photon collider if it exists.
