Summary: | In this paper, by using Feynman diagram techniques we have evaluated the
influence of the scalar unparticle and polarization at the muon colliders
through the leptonic and hadronic decays of W boson in the RS model. The
results show that with fixed collision energies, the total cross-sections for
leptonic and hadronic productions in final states depend strongly on the
parameters of the unparticle physics and muon beam polarization. The total
cross-sections achieve the maximum value when both of muon beams polarize left
or right and the minimum value when the $\mu^{-}$ beam polarizes left, the
$\mu^{+}$ beam polarizes right and vice versa. In case of the different
polarization, the cross-section increases as the collision energy increases and
it changes insignificantly in case of the unpolarized muon beams. In
particular, the cross-section for leptonic productions in final states is much
larger than that of hadronic productions under same conditions. With the
benchmark background $(\Lambda_{U}, d_{U})$ $= (1 $TeV$, 1.9)$, the
cross-sections reach the maximum value. The integrated luminosity value is
shown to correspond to a significance larger than $5\sigma$. |
