Abstract

The form factors of the decay K + → π 0 e + ν (K(e3)/ + ) have been measured with stopped kaons. A Dalitz plot containing 4.1 x 10 4 events was analyzed. A comparison of the observed Dalitz plot with a Monte Carlo simulation determined the ratio of the strengths of possible scalar and tensor couplings to that of the vector coupling, f(S)/f + (0) = -0.002 ± 0.026(stat) ± 0.014(syst) and f(T)/f + (0) = -0.01 ± 0.14(stat) ± 0.09(syst). These values are consistent with the standard model prediction of zero, and disagree with a previous experiment. The analysis also yielded the coefficient of the q 2 term in the vector form factor to be λ + = 0.0278 ± 0.0026(stat) ± 0.0030(syst). (C) 2000 Elsevier Science B.V.
