Abstract
A study of the centrally produced p (p) over bar, p (p) over bar pi(0), p ( p) over bar pi(+)pi(-) and Lambda Lambda channels has been performed in pp collisions using an incident beam momentum of 450 GeV/c. No significant new structures are observed in the mass spectra, however, important new inform ation on the production dynamics is obtained. A systematic study of the pro duction properties of these systems has been performed and it is found that these systems are not produced dominantly by double Pomeron exchange.
