Electromagnetic Dipole Moments and Radiative Decays of Particles from Exchange of Fermionic Unparticles
Yi Liao
We construct the propagator for a free fermionic unparticle field from basic considerations of scale and Lorentz invariance. The propagator is fixed up to a normalization factor wh…
Lepton Flavor Violating Muon Decays in a Model of Electroweak-Scale Right-Handed Neutrinos
Jian-Ping Bu, Yi Liao, Ji-Yuan Liu
The small neutrino mass observed in neutrino oscillations is nicely explained by the seesaw mechanism. Rich phenomenology is generally expected if the heavy neutrinos are not much…
Effects of Unparticles on Running of Gauge Couplings
Yi Liao
Unparticles charged under a gauge group can contribute to the running of the gauge coupling. We show that a scalar unparticle of scaling dimension d contributes to the βfunction a…
Long-range Electron Spin-spin Interactions from Unparticle Exchange
Yi Liao, Ji-Yuan Liu
Unparticles as suggested by Georgi are identities that are not constrained by dispersion relations but are governed by their scaling dimension, d. Their coupling to particles can r…
Impact of spin-zero particle-photon interactions on light polarization in external magnetic fields
Yi Liao
If the recent PVLAS results on polarization changes of a linearly polarized laser beam passing through a magnetic field are interpreted by an axion-like particle, it is almost cert…
Bounds on Unparticles Couplings to Electrons: from Electron g-2 to Positronium Decays
Yi Liao
Unparticles as suggested recently by Georgi have surprising phenomenological implications, distinctive from any other new physics that we know of. But they must interact very feebl…
