Spin alignment of K∗(892)±K^*(892)^\pm mesons produced in neutron-carbon interactions

A new precise measurements of spin density matrix element $\rho_{00}$ of $K^*(892)^{\pm}$ mesons produced inclusively in neutron-carbon interactions at \~60 GeV have been carried out in the EXCHARM experiment at the Serpukhov accelerator. The values of $\rho_{00}$ obtained in the transversity frame are $0.424\pm0.011(stat)\pm0.018(sys)$ for $K^*(892)^+$ and $0.393\pm0.025(stat)\pm0.018(sys)$ for $K^*(892)^-$. Significant $P_T$ dependence of $\rho_{00}$ has been observed in $K^*(892)^+$ production.Comment: 8 pages, LaTeX, 3 eps figure

Proton - Nucleus Interactions at 200-GeV/c

The investigation of interactions of hadrons with the nucleus in recent time became very important, and there is a hope that it can give the information about the systems produced in this process (lifetime, cross sections etc.) The nuclear photoemulsions are a good detector at the investigation of hadron-nucleus interactions due to a high spatial resolution and a possibility of detection of particles nearly at all energies that enables to study the characteristics of both fast and slow particles. The consistence of emulsion enables to obtain the characteristics of interactions both on light (CNO, <A> = 14) and on heavy(Ag,Br,<A> = 94) nuclei

E-by-e fluctuations of initial conditions in interactions of light, intermediate and heavy nuclei at energies 4 - 200 GeV per nucleon

A better understanding of initial conditions of nuclear interactions is one of the most important heavy ion physics problems. The paper considers these problems in the centrality selected interactions of light (C, O, Ne) – (beam) and heavy (Au, Pb) – (beam) ions with light (C/N/O) – (target) and heavy (Ag/Br) – (target) nuclei using the data of JINR-AGS-SPS target emulsion experiments with limited statistics. To reveal a possible system structure dependence, the analyses of E-by-E fluctuations on the longitudinal event shape and multiplicity have been performed, vertically and horizontally

Coherent Production of Particles by Protons at 200-GeV/c on Emulsion Nuclei

The coherent diffraction production process is characterized by a very narrow angular distribution of secondary particles that is caused by a small 4-momentum transferred to the nuclei. Besides, they have neither excitation of nuclei, nor disintegration. The quantum numbers of the coherently produced system are the same as those of the incident particle. For proton coherent interactions the number of charged particles must be odd. In this work are presented the data about a cross section for production of three, five and seven charged particles at 200 Gev/c, the energy dependence of these cross sections as angular characteristics of the secondary particles in coherent reactions

The Multiplicity in Fragmentation and Pionisation Regions in p p Interactions at 200-GeV/c

Two BR-2 emulsion stacks 20cm x 10cm x 100 x 0,06 cm in size were irradiated by 200 Gev/c protons at the NAL accelerator in Batavia (US). The scanning along the track was performed. They observed 9339 inelastic interactions on the track length of 3303 m of primary protons
