In this work, we investigate the sensitivity of the process
at LHC for the photonic 3- and 4-point functions that appear in non-commutative QED. We show that this process serves to study the behavior of the space-space as well as of the space-time non-commutativity. We also show that this process can probe the non-commutative scale
in the range of a few TeV.Received: 9 February 2004, Revised: 27 February 2004, Published online: 8 April 2004 相似文献

We study the helicity amplitudes of the process at high energy, which in the standard and SUSY models first arise at the one-loop order. In the standard model (SM), the
diagrams involve , charged-quark, and lepton loops, while in SUSY, we also have contributions from chargino-, charged-sfermion, and Higgs-loop
diagrams. The SUSY contributions are most important in the region above the threshold for producing the supersymmetric partners;
there, they interfere most effectively with the primarily imaginary SM amplitudes. Simple expressions for the relevant one-loop
functions are given which provide a direct overview of the behaviour of the helicity amplitudes in the whole parameter space
at high energies. The various characteristics of a large set of observables are studied in detail.
