/ Abstract
The azimuthal angular distribution of K + mesons has been measured in Au + Au collisions at 1 AGeV. In peripheral and semi-central collisions, K + mesons preferentially are emitted perpendicular to the reaction plane. The strength of the azimuthal anisotropy of K + emission is comparable to the one of pions. No in-plane flow was found for K + mesons near projectile and target rapidity.
