Abstract

In our previous paper [1] the 0(+) component of the K+pi(-) spectrum, which we denote (K pi)(0)*(0) , was modeled by the LASS parametrization, which consists of the K-0*(0)(1430) resonance together with an effective range nonresonant component. Because of a coding error the relative fractions of the resonance term, effective range term, and the interference between the two terms were incorrectly calculated. We have corrected the error and now find that the K-0*(0) (1430) resonance accounts for 81%, the effective range term 45%, and the destructive interference between the two terms the excess 26% of (K pi)(0)*(0). The incorrect values given on page 072003- 7 of the original paper were 66%, 20%, and 14%, respectively, and it was previously reported that the interference was constructive. We can now recalculate the branching fraction for B+ -> K-0*(0) (1430)pi(+) using our corrected knowledge of the composition of the (K pi)(0)*(0) component and find it to be: (44.4 +/- 2.2 +/- 2.0(-2.1)(+1.6) + 4.5) x 10(-6), where the first error is statistical, the second is systematic, the third is due to the uncertainty on the Dalitz- plot model, and the fourth error is due to the uncertainty on the branching fraction of K-0*(0) (1430) -> K pi combined with the uncertainty on the proportion of the (K pi)(0)*(0) component due to the K-0*(0) (1430) resonance. The incorrect value given on page 072003-10 of the original paper was (36.6 +/- 1.8 +/- 1.6 +/- 1.2 +/- 1.7 +/- 4.1) x 10(-6).
