Analysis of K e3+ decay

A study has been made of 2700 decays of the type K +→ π oe + v in the CERN 1.1 m 3 heavy liquid bubble chamber. The four-momentum transfer dependence of the form factor f +( q 2) has been determined. The usual linear parametrization f +( q 2) = f +(0) (1+ λ + q 2/ m 2 π ) gives λ + = 0.027 ± 0.010....

Summary:A study has been made of 2700 decays of the type K +→ π oe + v in the CERN 1.1 m 3 heavy liquid bubble chamber. The four-momentum transfer dependence of the form factor f +( q 2) has been determined. The usual linear parametrization f +( q 2) = f +(0) (1+ λ + q 2/ m 2 π ) gives λ + = 0.027 ± 0.010.
