Studies of K^+arrow μ^+ ν e^+ e^- and K^+ arrow e^+ ν e^+ e^-.
Abstract
Experiment E865 at Brookhaven has collected approximately 1,500 events of the decay K^+arrow μ^+ ν e^+ e^-, and 380 events of the decay K^+arrow e^+ ν e^+ e^-. The structure dependent parts of these radiative K_l2 decays are studied. Together, they provide the first measurement of the form factor R in the kaon system, and improved measurements of the form factors F_V, F_A. Preliminary results will be presented, and comparison to the existing data in the context of Chiral Perturbation Theory will be made.
