From the total contributions to a f from unparticles we obtain a constraint on the λ μi k parameters given by a quadric equation of twelve dimensions stands for the systematic and experimental errors of Δa μ with 2 standard deviations. Numerical evaluation shows that α μe k i s undefined in the interval where d U guarantees unitarity, Also; We can however project the quadric surface by requiring that λ μe k =0, thus the resulting constraint equation represents an eight dimensional hyperboloid hiper volume with parametric equations (Ω 6 cosh ϑ, Ω 2 sinh ϑ ), where: Ω 6 and Ω 2 represent a six and two dimensional ellipses.

but, what is the allowed interval for the hyperbolic angle ? VIII Latin American Symposium on High Energy Physics, Valparaíso, Chile, 6-12 December 2010

The presence of a non-zero d f would mean that there are both parity and time-reversal violation. In a world with perfect CPT symmetry, a search for d f would also be a direct test of CP symmetry  J. Bailey et al., J. Phys. G 4, 345 (1978) The dipole magnetic moment of a fermion l is related to the T violating form factor F 3 (q 2 ) term of the photon-lepton vertex function Γ μ as follows: The experimental limit on the electric dipole moments [ e-cm ] with 95% C.L. and the theoretical standard model values are: VIII Latin American Symposium on High Energy Physics, Valparaíso, Chile, 6-12 December 2010

The presence of a non-zero d f would therefore signify the existence of both parity and time-reversal violation. In a world with perfect CPT symmetry, a search for d f would also be a direct test of CP symmetry  J. Bailey et al., J. Phys. G 4, 345 (1978) Unparticle contribution to EDM is induced by interference of scalar (vector) and pseudo scalar (axial) operators: where VIII Latin American Symposium on High Energy Physics, Valparaíso, Chile, 6-12 December 2010

 J. Bailey et al., J. Phys. G 4, 345 (1978) we used the parameterization of the hyperboloid (Ω 6 cosh ϑ, Ω 2 sinh ϑ ) to correctly use the phenomenological bound of effective parameters discussed above, and we found: our prediction is well above the experimental bound!

There are other possibilities for the hyperbolic angle: and λ μi p small and vanishing vector-axial contribution to EDM and λ μi p small and nonvanishing vector-axial contribution to EDM andAll effective parameters about the same order of magnitude VIII Latin American Symposium on High Energy Physics, Valparaíso, Chile, 6-12 December 2010

VIII Latin American Symposium on Higth Energy Physics, Valparaíso, Chile, 6-12 December We find phenomenological bounds for some effective parameters ( λ μi k ) on framework of Unparticles Physics Model. 2.The muon electric dipole moment( d μ ) induced by unparticles operators show a complex structure of the coupling parameters. Therefore it reveals an new phases of CP violation. 3.Since the muon electric dipole moment depends very much on the different phases of the effective parameters, it is more sensitive than the standard model approach.
