A study is made of the average multiplicity of secondary charged particles, the distributions of ..pi../sup + -/ mesons in the Feynman variable x and in rapidity y, and the azimuthal correlations in ..pi../sup -/p interactions at 40 GeV/c with production of particles having large transverse momenta (p> or =0.8 GeV/c). It is found that the average multiplicity of charged particles in events where particles with p/sub perpendicular/> or =0.8 GeV/c are produced is higher than the average. It is shown that the charge asymmetry of the pions increases with increase of p/sub perpendicular/, which appears especially for y> or =0.5. The correlation observed in the azimuthal plane in the emission of pions with respect to the particle with p/sub perpendicular/> or =0.8 GeV/c may indicate the presence of jets of pions accompanying particles with large transverse momentum.
