Περίληψη:
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 information on the production dynamics is obtained. A
systematic study of the production properties of these systems has been
performed and it is found that these systems are not produced dominantly
by double Pomeron exchange. (C) 1999 Published by Elsevier Science B.V.
