The measurement of the transverse polarization of \(\Lambda\) hyperons produced in nC reactions in the EXCHARM experiment

The measurement of the transverse polarization of \(\Lambda\) hyperons produced in nC reactions in the EXCHARM experiment

New precise data of the \(\Lambda^0\) polarization are obtained in the EXCHARM experiment at the Serpukhov accelerator. The \(\Lambda^0\)s have been produced in nC interactions in the neutron energy interval 40–70 GeV and detected in the kinematic range of \(0.1\lesssim x_{\mathrm{F}} \lesssim 0.6\)...

Zusammenfassung:New precise data of the \(\Lambda^0\) polarization are obtained in the EXCHARM experiment at the Serpukhov accelerator. The \(\Lambda^0\)s have been produced in nC interactions in the neutron energy interval 40–70 GeV and detected in the kinematic range of \(0.1\lesssim x_{\mathrm{F}} \lesssim 0.6\) and \(0.2\le p_{\mathrm{t}} \le 1.2\) GeV/c. The obtained results are compared with other measurements in the pp and pA interactions.
