英文摘要: We study inclusive production of doubly heavy baryon at a e(+)e(-) collider and at hadron colliders through fragmentation. We study the production by factorizing nonpertubative and perturbative effects. In our approach the production can be thought as a two-step process: a pair of heavy quarks can be produced perturbatively and then the pair is transformed into the baryon. The transformation is nonperturbative. Since a heavy quark moves with a small velocity in the baryon in its rest frame, we can use NRQCD to describe the transformation and perform a systematic expansion in the small velocity. At the leading order we find that the baryon can be formed from two states of the heavy-quark pair, one state is with the pair in S-3(1) state and in color 3, another is with the pair in S-1(0) state and in color 6. Two matrix elements are defined for the transformation from the two states, their perturbative coefficients in the contribution to the cross section at a e+e- collider and to the function of heavy quark fragmentation are calculated. Our approach is different than previous approaches where only the pair in S-3(1) state and in color is taken into account. Numerical results for e(+)e(-) colliders at the two B-factories and for hadronic colliders LHC and Tevatron are given. (C) 2003 Published by Elsevier B.V.
