Meson resonance creation in carbon-carbon interactions at 4.2 AGeV/c

We present results on investigations of the invariant mass distributions and transverse momentum spectra of 0(770) meson in C+C collisions at 4.2 AGeV/c. We used a 2-m propane bubble chamber exposed to beams from the Dubna synchrophasotron. From invariant masses of pion pairs the mass and the width of the rho meson were obtained. The 0/ - ratio was estimated, as well as, mean transverse momentum pT 'src='http://proceedings.aip.org/stockgif3/rang.gif' align=middle border=0 > . Average transverse momentum pT 'src='http://proceedings.aip.org/stockgif3/rang.gif' align=middle border=0 > dependencies of mass of stable particles - and p and 0 and resonances have been analyzed and compared with other experiments.
