Hawking radiation of unparticles

Understand

Unparticle degrees of freedom, no matter how weakly coupled to the standard model particles, must affect the evolution of a black hole, which thermally decays into all available degrees of freedom.

• We develop a method for calculating the grey-body factors for scalar unparticles for 3+1 and higher dimensional black holes.
• We find that the power emitted in unparticles may be quite different from the power emitted in ordinary particles.
• Depending on the parameters in the model, unparticles may become the dominant channel.
