Gauged and ungauged unparticles signal at the LHC and ILC

Abstract

A novel scalar and tensor unparticles contribution to the polarized diphoton production at the LCH and ILC are studied and the effects of the conformal as well dimensions scales are discussed. The expression of the various subprocess helicity amplitudes is also presented. Moreover, the effect of spin 0 and spin ½ gauged unparticles on the decay rates ℎ → and ℎ → are also shown explicitly.

Dynamical Study of a Constant Viscous Dark Energy Model in Classical and Loop Quantum Cosmology

“…It is important to mention that all strong singularities (big rip) are absent in LQC for isotropic and homogenous universes (like FRW) where the Ricci scalar and similarly other curvature invariants are bounded for all the events where the energy density diverges. [34,35] As shown in Ref. [36], where a dynamical study of a phantom scalar field dark energy interacting with dark matter was carried out in LQC, the big rip singularity can be avoided and the role of the loop quantum gravity effect was to break the stability of the initially phantom field climbing up the potential and leave that of the rolling down the potential.…”
