Disentangling the Unparticles with polarized beams at e+e- colliders
arXiv:0711.4754 · doi:10.1103/PhysRevD.77.035015
Abstract
Recently proposed idea of unparticles arising due to a scale invariant sector in the theory can give rise to effective operators with different Lorentz structures. We show that by using the different polarization options at the future linear e+e- colliders, the nature of these effective operators can be easily understood. The unique feature of a complex phase in the propagator of the unparticle can also be understood uniquely for the different spins by exploiting the initial beam polarizations at the International Linear Collider (ILC).
