Unparticle physics.
I discuss some simple aspects of the low-energy physics of a nontrivial scale invariant sector of an effective field theory-physics that cannot be described in terms of particles. I argue that it is important to take seriously the possibility that the unparticle stuff described by such a theory might actually exist in our world. I suggest a scenario in which some details of the production of un...
متن کاملUnparticle physics at the photon collider
Recently, a conceptually new physics beyond the Standard Model (SM), unparticle, has been proposed, where a hidden conformal sector is coupled to the SM sector through higher dimensional operators. In this setup, we investigate unparticle physics at the photon collider, in particular, unparticle effects on the γγ → γγ process. Since this process occurs at loop level in the SM, the unparticle ef...
متن کاملAnother odd thing about unparticle physics
The peculiar propagator of scale invariant unparticles has phases that produce unusual patterns of interference with Standard Model processes. We illustrate some of these effects in e+e− → μ+μ−. © 2007 Elsevier B.V. All rights reserved.
متن کاملUnparticle Physics And Gauge Coupling Unification
Unparticle physics from a hidden conformal sector can alter the evolution of the Standard Model (SM) gauge couplings via TeV scale threshold corrections. We discuss how this may lead to gauge coupling unification at MGUT ≈ 2 × 10 15 GeV – 5 × 10 GeV without introducing new particles in the SM sector. 1 On leave of absence from: Andronikashvili Institute of Physics, GAS, 380077 Tbilisi, Georgia....
متن کاملUnparticle Physics on Cosmic Ray Photon and E
We study the effects of unparticle physics on the cosmic ray photon and e, including on the pair production (PP) and elastic scattering (ES) of cosmic ray photon off various background radiations, and on the inverse Compton scattering of cosmic ray e with cosmic radiations. We compute the spin-averaged amplitudes squared of three processes and find that the advent of unparticle will never signi...
