Large angle production of stable particles heavier than the proton and a search for quarks at the CERN intersecting storage rings

Measurements have been performed on production of particles with mass >1.5 GeV/c/sup 2/ and charge >or=2/3 for theta /sub lab/=62.5 degrees and square root s=53 GeV. At p/sub T/=0.7 GeV/c the relative rate of production of antideuterons to pi /sup -/ is (5+or-1)*10/sup -5/. The deuteron to ant...

Descripción
Sumario:Measurements have been performed on production of particles with mass >1.5 GeV/c/sup 2/ and charge >or=2/3 for theta /sub lab/=62.5 degrees and square root s=53 GeV. At p/sub T/=0.7 GeV/c the relative rate of production of antideuterons to pi /sup -/ is (5+or-1)*10/sup -5/. The deuteron to antideuteron ratio is 3.7+or-1.2. No new stable particle has been seen amongst 0.7*10/sup 8/ charged particles entering our detector. (7 refs).
