| Observation of Multi Parton Interaction in pA-Collisions at 70 GeV | ||
| – Protvino, 2005. – p. 7, fig. 8, tables 1, refs.: 11. | ||
Production of hadron pairs with transverse momentum more than 1 GeV/c in collisions of 70 GeV protons off nuclei is measured. The obtained exponent for A-dependence for non-coplanar hadron pairs is substantially higher than for coplanar hadron pairs. Such dependence of the hadron pair production on atomic mass number can be explained by the contribution of multi parton interactions into pA-collisions.
