Charm hadron properties in 360 GeV/c π− p-interactions

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

A study of the properties of charm particles produced in 360 GeV/c π- p interactions is reported. The experiment was performed using the high resolution hydrogen bubble chamber LEBC in association with the European Hybrid Spectrometer at the CERN SPS. Details of the exposure and operation of the spectrometer are given and the methods used to extract the charm data are presented. The essential physics results on the decay properties (lifetime, branching ratios) as well as on the hadroproduction properties (cross sections forD,\(\bar D\),F, Λ c ,D, correlations between charm particles) are given.
