A study of kinematical correlations between charmed particles produced in $\pi$-Cu interactions at $\sqrt{s} = 26 GeV$

A sample of 475 events, in which two charmed-particle decays are observed, is analyzed to determine distributions of two-particle kinematic variables. One charmed particle with $x_F > 0$ is fully reconstructed and the other is at least partially recontructed. The distributions of $\Delta\phi$ and...

Descripción
Sumario:A sample of 475 events, in which two charmed-particle decays are observed, is analyzed to determine distributions of two-particle kinematic variables. One charmed particle with $x_F > 0$ is fully reconstructed and the other is at least partially recontructed. The distributions of $\Delta\phi$ and $p_T^2$ are compared with a next-to-leading order QCD calculation.
