On Unparticles and K+ to pi+ Missing Energy

High Energy Physics - Phenomenology 2007-12-27 v1

Abstract

We analyze the branching ratio and spectrum for the decay mode K+π++K^+ \to\pi^++{\not}E(missing energy) in the unparticle model, where an unparticle can also serve as the missing energy. A vector unparticle can even mediate the K+π++ννˉK^+ \to \pi^+ +\nu \bar{\nu}, resulting complicated interference with the Standard Model.
