coalescence model production

description

Deuteron and anti-deuteron production in Z decays has been observed in the ALEPH experiment at LEP. The production rate of anti-deuterons is measured to be per hadronic Z decay in the anti-deuteron momentum range from 0.62 to 1.03 GeV/c. The coalescence parameter , which characterizes the likelihood of anti-deuteron production, is measured to be in Z decays. These measurements indicate that the production of anti-deuterons is suppressed in collisions compared to that in pp and photoproduction collisions
