Abstract

We have searched for the proton decay mode p → ν K⁺ using the one-kiloton Soudan 2 high resolution calorimeter. Contained events obtained from a 3.56 kiloton-year fiducial exposure through June 1997 are examined for occurrence of a visible K⁺ track which decays at rest into μ⁺ ν or π⁺ π⁰. We found one candidate event consistent with background, yielding a limit, τ/B(p → ν K⁺) > 4.3 × 10³¹ years at 90% CL with no background subtraction.
