Origin of "direct" leptons
Dologshein B. A. , Nikitin Yu. P., Rozhnov G. V.
Experiments are analyzed on processes of the type p+ N—>/* + X, in which "direct" leptons with large transverse momenta are detected. It is shown that an appreciable contribution to such processes is made by the decays ψ(Μ05)-Λ + +1
