胶子湮灭生成中性MSSM黑格斯玻色子对的计算(英文)

Pair Production of Neutral MSSM Higgs Boson via Gluon Fusion

给出高能ｐｐ 碰撞中产生最小超对称中性黑格斯玻色子对的截面．在计算ｇｇ→ｈｈ 过程中，考虑了相关圈图的所有夸克和标量夸克的贡献．结果表明在ｐｐ 高能碰撞 ｓ ＝ １４ Ｔｅ Ｖ，黑格斯玻色子质量 ｍ ｈ ＝ １００ Ｇｅ Ｖ～６００ Ｇｅ Ｖ 时，截面为１６ｆｂ ～１０ｆｂ ．

The cross sections for the pair production of the neutral Higgs boson at high energy pp colliders are presented in the framework of the Minimal Supersymmetric extension of the Standard Model (MSSM). The pair production of Higgs bosons at the hadron collider is studied via gluon fusion process gg→hh, where all quarks and scalar quarks are taken with in the relevant loop diagrams. The cross section is found in the range of 16 fb～10 fb for Higgs boson (h) masses of 100 GeV～600 GeV in pp collisions at s=14 TeV.
