Abstract

A coupled channel analysis of the centrally produced K+ K- and π+ π- final states has been performed in pp collisions at an incident beam momentum of 450 GeV/c. The pole positions and branching ratios to ππ and KK̄ of the f0(980), f0(1370), f0(1500) and f0(1710) have been determined. A systematic study of the production properties of all the resonances observed in the π+ π- and K+ K- channels has been performed.
