A coupled channel analysis of the centrally produced K+K- and pi+pi- final states in pp interactions at 450 GeV/c

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/178749A coupled channel analysis of the centrally produced K+K- and pi+pi- final states has been performed in pp collisions at an incident beam momentum of 450 GeV/c. The pole positions and branching ratios to pipi and KK 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 pi+pi- and K+K- channels has been performed.16 pages, Latex, 5 FiguresHigh Energy Physics - ExperimentA coupled channel analysis of the centrally produced K+K- and pi+pi- final states in pp interactions at 450 GeV/ctext
