L. Alvero et al., PROBING SMALL-X PARTON DENSITIES IN PROTON-PROTON(-NUCLEUS) COLLISIONS IN THE VERY FORWARD DIRECTION, Physical review. D. Particles and fields, 57(7), 1998, pp. 4063-4068
We present calculations of several pp scattering cross sections with p
otential applications at the CERN LHC. Significantly large rates for t
he momentum fraction x, as low as 10(-7), are obtained, allowing for p
ossible extraction of quark and gluon densities in the proton and nucl
ei down to these small x values provided a detector with good acceptan
ce at maximal rapidities is used. [S0556-2821(98)01409-X].
