A phenomenological renormalization scheme for hadronic diffraction is proposed, which unitarizes the triple-pomeron Regge amplitude while preserving its

...single diffractive, double diffractive and double pomeron exchange cross sections are presented and compared with experimental results. A new interpretation of hard and deep inelastic diffractive data emerges in which the momentum sum rule is obeyed by the constituents of a pomeron described as a mixture of quark and gluon color singlets in a ratio dictated by asymptopia.
Using Regge theory at Born level and with eikonalized amplitudes we obtain for the pomeron intercept the values 1.104 and 1.122, respectively, from global fits to total cross section and ϱ-value data ...for

We describe a detector designed to measure the position of electrons and photons in the new CDF Plug Upgrade Calorimeter. The detector comprises 6400 individual scintillator strips placed at the ...shower maximum location of the electromagnetic calorimeter section and coupled to wave-length-shifting fibers read-out by multi-anode photomultipliers. We describe the design criteria, the R&D studies that led to the choice of scintillator and fiber, the mechanical assembly, and the quality control tests during production and assembly of the detector elements.
