We report a study of the central exclusive production of {pi}{sup +}{pi}{sup -} and K{sup +}K{sup -} pairs in high energy hadron-hadron collisions. The amplitude is calculated in the Regge approach including both pomeron and secondary reggeon exchanges and absorption effects due to proton-proton interaction and {pi}{pi} (KK) rescattering. We discuss a measurement of exclusive production of a scalar {chi}{sub c0} meson via {chi}{sub c0}{yields}{pi}{sup +}{pi}{sup -}, K{sup +}K{sup -} decay. We…

Modelling exclusive meson pair production at hadron colliders
We present a study of the central exclusive production of light meson pairs, concentrating on the region of lower invariant masses of the central system and/or meson transverse momentum, where
Central exclusive production within the Durham model: A Review
We review recent results within the Durham model of central exclusive production. We discuss the theoretical aspects of this approach and consider the phenomenological implications in a variety of
