At high energy hadron collider, the dominant production mechanism for heavy baryons is actually the fragmentation. We analytically have computed the effect of spin orientation of heavy quarks Q in the production heavy triply baryons through fragmentation in leading order perturbative QCD. Our analytical results have been presented for the spin dependent fragmentation Functions for fragmentation processes b→𝛺bbc and c→𝛺ccb. The production of intermediate spin 1/2 and 3/2 excited states is explicity included. The global fragmentation probabilities fall off within the range of 10−5–10−6. After evaluation of fragmentation functions by Altareli-Parisi equation, cross section production of all case 𝛺bbc and 𝛺ccb at the LHC. (\( \sqrt{S}=14\mathrm{TeV} \)) have been calculated. The total cross section production falls off within the range 21–166 pb.

自旋取向夸克对LHC重三重子截面生成的影响(S = 14 TeV $$ \ sqrt {S} = 14 \ mathrm {TeV} $$)

在高能强子对撞机上,重子的主要产生机理实际上是碎片。我们通过分析先导扰动QCD中的碎裂来计算重夸克Q在生产重三重子中的自旋取向的影响。我们的分析结果已针对碎片过程b→fragment bbc和c→𝛺 ccb的自旋相关性碎裂函数给出。明确包括中间自旋1/2和3/2激发态的产生。全局碎片概率落在10 -5 –10 -6的范围内。通过Altareli-Parisi方程评估碎裂函数后,所有情况的横截面production英国广播公司(LHC)的BBC和at ccb。(\(\ sqrt {S} = 14 \ mathrm {TeV} \))已计算出来。总横截面产量落在21–166 pb的范围内。
