| Summary: | 碩士 === 國立臺灣師範大學 === 物理學系 === 96 === We study the muon pair production in electron-positron collision in the presence of an unparticle with a low energy scale invariance breaking. The breaking, possibly due
to Higgs VEV, generates a mass gap μ in the unparticle continuous mass spectrum. This effect is incorporated into the unparticle propagator in a way that renders smooth
transition to a massive particle propagator as unparticle dimension approach one. We concentrate especially in the most likely case μ ≈ MZ and Z μ > M and discuss in muon pair production how to distinguish the original unparticle and the unparticle with mass gap μ.
