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.[11]. 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 study unparticle physics effects in Λb → Λ + missing energy decay with polarized Λb and Λ baryons. The sensitivity of the branching ratio of this decay and polarizations of Λb and Λ baryons on the scale dimension dU and effective cut–off parameter ΛU are discussed. e-mail: [email protected] permanent address:Institute of Physics,Baku,Azerbaijan e-mail: [email protected]

A method to solve the static field equation of the Faddeev model is presented. For an special combination of the concerned field, we adopt a form which is compatible with the field equation and involves two arbitrary complex functions. As a result, the static field equation is reduced to a set of first order partial differential equations. ——————————————————————————————— Corresponding author: C...

An attempt has been made to address the 3σ anomaly of the forward-backward asymmetry of b quark in LEP data via an unparticle sector. For most part of the parameter space except certain particular regions, the anomaly could not be explained away plausibly, when constraints from other LEP observables are taken into account.
