Abstract
A coupled channel analysis of the centrally produced K+K- and pi(+)pi(-) fi nal states has been performed in pp collisions at an incident beam momentum of 450 GeV/c. The pole positions and branching ratios to pi pi and K (K) o ver bar of the f(0)(980), f(0)(1370), f(0)(1500) and f(0)(1710) have been d etermined. A systematic study of the production properties of all the reson ances observed in the pi(+)pi(-) and K+K- channels has been performed. (C) 1999 Elsevier Science B.V. All rights reserved.
