Abstract
Vector meson production is studied in the reaction γγ→K+ K− π+ π− . A clear Φ(1020) signal is seen in theK+ K− mass distribution and aK*0 (890) signal is visible in theK± π∓ one. Both do not seem to be strongly correlated with quasi two body final states. Cross sections for the processes γγ→K+ K− π+ π− , γγ→Φπ+ π− , γγ→K+0 K± π∓ and upper limits for the production of Φp, ΦΦ andK*0 $$\overline {K^{ * 0} } $$ are given as function of the invariant γγ mass.
