Abstract

Evidence for the forward production of D + mesons has been found in pp collisions at a c.m. energy of 52.5 GeV. A signal of 92 ± 18 events above background has been observed in the decay channel D + → K ∗ o π + → K −π +π + . The cross section in the phase space region of our experiment is given and implications for the total cross section for charmed D meson production are discussed.
