Description

A model in which Q1 and Q2 resonance contributions add coherently to a Gaussian background is shown to reproduce the mass dependence of the Jsup(P)=1+K*π and rhoK partial waves in K+-p→K+-π+π-p at 13 GeV/c. Through a fit to the data, the mass and total width for Q1 are found to be m=1289+-3+-(25) MeV, GAMMA=150+-9(+-70) MeV and for Q2, m=1404+-3(+-10) MeV, GAMMA=142+-4(+-15) MeV, where estimated systematic errors are given in parentheses. While a significant background is required for the 1+K*π system, none is needed for the 1+rhoK system. (Auth.)
