“…Thus, experimentally, if we measure a reasonable pairs of photons with lower values of the invariant mass, the signature of the new physics will be that of the scalar unparticles. For the subprocess → , at the ILC energies, we have also studied the effects of the scalar and tensor unparticles [6]. We can improve the ratio signal/background by choosing appropriate polarizations of the initial beam.…”

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.
