Description
In view of the recent diffractive dijet data from CDF
RunII, we critically re-evaluate the standard approach to the
production of high-mass systems in proton/antiproton collision. A
central exclusive dijet production is characterized by a large
separation in rapidity of the final products and by few hadronic
remnants. This mode of production is interesting because, from the
measurement of the momenta of the daughter proton and antiproton, it
is possible to reconstruct the mass of the centrally produced system
without detecting it. Typical calculations of central exclusive
production are divided in five pieces, the lower order QCD calculation
and four corrections that can be large and leads to large
uncertainties on the value of the cross section. All the arguments
developed here can be used in order to improve our understanding of
Higgs boson exclusive production.
