Unparticles in diphoton production to NLO in QCD at the LHC
arXiv:0804.4054 · doi:10.1103/PhysRevD.79.075012
Abstract
We compute to next-to-leading order in QCD the tensor unparticle contribution to the diphoton production at the LHC, wherein the unparticle sector is a consequence of (a) scale invariance but not full conformal invariance and (b) conformal invariance. We use the semi-analytical two cutoff phase space slicing method to handle the corrections to the and show that our results are insensitive to the soft and collinear cutoffs. In order to avoid the contribution of the photons due to fragmentation, we employ the smooth cone isolation criterion. Significance of the QCD corrections to the diphoton events including unparticles is highlighted.
