Factorization Approach for Inclusive Production of Doubly Heavy Baryon

Abstract

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 ${}^3{S}_1$ state and in color $\bar{3}$, another is with the pair in ${}^1{S}_0$ 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 ${}^3{S}_1$ state and in color $\bar{3}$ is taken into account. Numerical results for $e^{+}{e}^{-}$ colliders at the two $B$-factories and for hadronic colliders LHC and Tevatron are given.
