Gluinonia:能级、产生和衰变

Gluinonia: Energy Levels, Production and Decay

Matthias R. Kauth, Johann H. Kuhn, Peter Marquard, Matthias Steinhauser

摘要:

对非相对论性束缚态--胶子的能级、产生和衰变速率进行了预测。色八重态组分之间的势是以次-领先阶导出的,并且对产生截面和衰变到胶子喷注的速率导出了单圈QCD修正。此外,我们评估衰变到顶夸克和两个光子的速率。的信号与背景的比例估计为主导的衰变模式,并发现约为0.5%。因此,对于相对较轻的胶子,束缚态可能是可探测的。

英文摘要:

Predictions for energy levels, production and decay rate of gluinonia, non-relativistic boundstates of gluinos, are presented. The potential between color-octet constituents is derived in next-to-next-to leading order and one-loop QCD corrections are derived for the production cross section and the decay rate into gluon jets. In addition we evaluate the decay rate into top quarks and into two photons. The signal-to-background ratio is estimated for the dominant decay mode and found to be around 0.5%. For relatively light gluinos the bound states thus might be detectable.
