Title: Search for the decays [ital K][sup +][r arrow][pi][sup +][nu][bar [nu]] and [ital K][sup +][r arrow][pi][sup +][ital X0] for 150[lt][ital M][sub [ital X]][sup 0][lt]250 MeV/[ital c][sup 2]

Abstract

A search for the decays [ital K][sup +][r arrow][pi][sup +][nu][bar [nu]] and [ital K][sup +][r arrow][pi][sup +][ital X0], where [ital X][sup 0] is any weakly interacting neutral particle or system of neutral particles with 150[lt][ital M][sub [ital X]][sup 0][lt]250 MeV/[ital c][sup 2], was performed in the pion kinematic region below the [ital K][sub [pi]2]([ital K][sup +][r arrow][pi][sup +][pi][sup 0]) peak. An upper limit on [ital B]([ital K][sup +][r arrow][pi][sup +][nu][bar [nu]]) is set at 1.7[times]10[sup [minus]8] (90% C.L.) and [ital B]([ital K][sup +][r arrow][pi][sup +][ital X0]) is restricted to the 10[sup [minus]7] level or lower. Limits are also set for the production of [ital K][sup +][r arrow][pi][sup +][nu][bar [nu]] through scalar or tensor interactions at 1.8[times]10[sup [minus]8] and 1.0[times]10[sup [minus]8] (90% C.L.), respectively.
