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

The forward elastic scattering of light on light, i.e., the reaction in the forward direction, is analyzed utilizing real analytic amplitudes. We calculate , the ratio of the real to the imaginary portion of the forward scattering amplitude, by fitting the total cross section data in the high energy region 5 GeV GeV, assuming a cross section that rises asymptotically as ln2 s. We then compare , the ratio of the even portions of the pp and forward scattering amplitudes, as well as to [1], the value for Compton scattering. Within errors, we find that the three -values in the c.m.s. energy region 5 GeV 130 GeV are the same, as predicted by a factorization theorem of Block and Kaidalov [2].
