Search for the proton decay mode p {r_arrow} v K{sup +} in Soudan 2.
We have searched for the proton decay mode p {yields} {nu} K{sup +} 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{sup +} track which decays at rest into {mu}{sup +}{nu} or {pi}{sup +}{pi}{sup 0}. We found one candidate event consistent with background, yielding a limit, {tau}/B(p {yields} {nu} K{sup +})>4.3x10{sup 31} years at 90% CL with no background subtraction.
