Asymmetries have been measured as a function of x_F and p_T**2 over the range -0.12 < x_F < 0.12 and p_T**2 < 4$ (GeV/c)**2 for hyperons and -0.1 < x_F < 0.3 and p_T**2 < 8 (GeV/c)**2 for the Lambda_c baryons. We observe clear evidence of leading particle effects and a basic asymmetry even at x_F=0. These are the first high statistics measurements of the asymmetry in both the target and beam fragmentation regions in a fixed target experiment.", "revisions": [ { "version": "v1", "updated": "1999-12-17T17:17:03.000Z" } ], "analyses": { "keywords": [ "nucleon interactions", "antiparticle asymmetries", "production", "first high statistics measurements", "beam fragmentation regions" ], "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "inspire": 511790, "adsabs": "1999hep.ex...12039J" } } }
