Abstract

: In this work, we study the production of  boson pairs from  collisions in a muon collider within the framework of the Standart Model (SM) and the Unparticle Physics (UP) model, considering polarized muon and anti-muon beams. The results show that the total cross-section (TCS) increases as the center of mass energy () increases, the TCS has the largest value when both the and  particle beams are left polarized. The contribution of scalar unparticles is substantial in the case of oppositely polarized  particle beams. For scaling dimension  the differential cross-section (DCS) reaches a large value when  and the kinetic energy of the resulting Z boson beam is greater than 4 TeV. For the case  the density of points representing DCS with large values is evenly distributed throughout the entire survey domain.
