Antisymmetric rank--2 tensor unparticle physics

摘要: We present the phenomenology of antisymmetric rank-2 tensor unparticle operator O{sub U,A}{sup {mu}}{sup {nu}} with scaling dimension d{sub U}. consider physical effects in Z{sup 0} boson invisible decays 0}{yields}U, 0}{yields}bb channel, electroweak precision observable S parameter, and muon anomalous magnetic dipole moment. The decay gives a very stringent constraint ({lambda}{sub U},M{sub U}) plane, only small r{identical_to}{lambda}{sub U}/M{sub U} < or approx. 0.1 is favored, when {lambda}{sub order several 100 GeV. When phenomenological parameter {mu}, which parameterizes scale invariance breaking, goes to 0, (g-2) diverge for 1
