强子对撞机上胶子对产生的束缚态效应

Bound-state effects on gluino-pair production at hadron colliders

Kaoru Hagiwara, Hiroshi Yokoya

摘要:

在标准模型的最小超对称扩展下,研究了强子对撞机上束缚态对胶子对产生的影响。由于预期的大质量和八重态色荷的胶子,束缚态效应可以在大型强子对撞机上是实质性的。我们发现了一个质量阈值附近的胶子对的不变质量分布的显着变形,以及一个额外的修正的总截面。不变质量分布和对总截面的修正都依赖于胶子的衰变宽度。

英文摘要:

We study bound-state effects on the pair production of gluinos at hadron colliders, in a context of the minimal supersymmetric extension of the standard model. Due to the expected large mass and the octet color-charge of gluinos, the bound-state effects can be substantial at the LHC. We find significant deformation of the invariant-mass distributions of a gluino-pair near the mass threshold, as well as an additional correction to the total cross-section. Both the invariant-mass distribution and the correction to the total cross section depend crucially on the decay width of the gluino.
