Unparticle as a field with continuously distributed mass
نویسنده
چکیده
We point out that the notion of an unparticle, recently introduced by Georgi, can be interpreted as a particular case of a field with continuously distributed mass considered in ref.[14]. We also point out that the simplest renormalizable extension of the SU c (3)⊗SU L (2)⊗U (1) Standard Model is the extension with the replacement of the U (1) gauge propagator 1 k 2 → 1 k 2 + ∞ 0 ρ(t) −t+k 2 +iǫ dt with ∞ 0 ρ(t)dt < ∞.

We discuss what can be learned about unparticle physics by studying simple quantum field theories in one space and one time dimension. We argue that the exactly soluble 2D theory of a massless fermion coupled to a massive vector boson, the Sommerfield model, is an interesting analog of a Banks-Zaks model, approaching a free theory at high energies and a scale invariant theory with nontrivial an...
متن کاملA Note on Unparticle Decays
The coupling of an unparticle operator OU to Standard Model particles opens up the possibility of unparticle decays into standard model fields. We study this issue by analyzing the pole structure (and spectral function) of the unparticle propagator, corrected to account for one-loop polarization effects from virtual SM particles. We find that the propagator of a scalar unparticle (of scaling di...
متن کاملEffects of unparticles on running of gauge couplings
Unparticles charged under a gauge group can contribute to the running of the gauge coupling. We show that a scalar unparticle of scaling dimension d contributes to the β function a term that is (2−d) times that from a scalar particle in the same representation. This result has important implications on asymptotic freedom. An unparticle with d > 2, in contrast to its matter counterpart, can spee...
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...
