    • 利用電子-正電子對撞來找出質量連續分佈之粒子的特性及尺度對稱性被破壞所產生的影響

    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.
