We present a measurement and partial wave analysis of the nal state KLK of pp annihilation at rest in liquid hydrogen. This reaction is important for the study of the KK decay mode of scalar resonances, in particular the isovectors a0(980) and a0(1450). The determination of the a0(1450) production also xes the KK coupling of the isoscalar f0(1500) which is discussed as a glueball. We nd B( pp! a0(1450) ; a0(1450)! KK) = (8:88 1:68) 10 4 and hence B( pp ! f0(1500) ; f0(1500)! KK) = (4:52 0:36) 10 4 . The mass and width of a0(1450) arem = 1480 30 MeV/c2 and = 265 15 MeV/c2, respectively. For a0(980) we determine the relative ratio B( pp! a0 ; a0! KK)/ B( pp! a0 ; a0! ) = 0:23 0:05 and its relative coupling, KK to , is 1:03 0:14. 13.25.-k, 14.40.Cs, 14.40.Ev Typeset using REVTEX 3
