Constraints on unparticle interactions from particle and antiparticle oscillations
2009
European Physical Journal C: Particles and Fields
We study unparticle effects on particle and antiparticle osillations in meson-antimeson, and muonium-antimuonium systems. Unlike usual tree level contributions to meson oscillations from heavy particle exchange with small Γ_12, the unparticle may have sizeable contributions to both M_12 and Γ_12 due to fractional dimension d_ of the unparticle. We find that very stringent constraints on the unparticle and particle interactions can be obtained. If unparticle effect dominates the contributions
