A cross section measurement of charm hyperons Ξc+ and Ξc0 in 250 GeV p/K/π-nucleon interactions

Creators

Description

Fermilab Experiment 769 used a charge-selected, hadron beam of mean energy 250 GeV/c, composed of pions, kaons, and protons, impinging on beryllium, aluminum, copper and tungsten targets. Using a sample of approximately 4000 Ξs- → Λ0π- decays, measurements of the charm baryon forward cross sections times branching ratio π±N → Ξc+X and π±N → Ξc0X are presented. Upper limits on α x BR are also determined for the states Ξc+ → Ξs-π+π+ and Ξc0 → Ξs-π+ produced in (p, π+, π-, K+, K-)-nucleon interactions
