分析了在大型强子对撞机上探测slepton的可能性。我们比较了不同的轻子对产生机制qq_∞、WW、gg → l_∞,发现小的qq_∞截面是最大的。虽然虽然电弱和强背景往往很大,但我们表明,通过适当的切割,在LHC(SSC)上可能观测到质量高达250(350)GeV的slepton,发现极限为10个事件,积分光度为10−4pb−1。在大型强子对撞机的高吉诺衰变中也可以单独产生睡眠子。在特定的模型中,在这些过程中可以观察到相对较轻的sleptons。
We analyse the possibility of detecting sleptons at large hadron colliders. We compare the different slepton-pair-production mechanisms, qq̄, WW, gg → l ≈ l ∽ , finding that the small qq̄ cross section is the largest one. Although Although electroweak and strong backgrounds tend to be large, we show that with appropriate cuts it may be possible to observe sleptons with a mass up to 250 (350) GeV at LHC (SSC), for a discovery limit of 10 events and an integrated luminosity of 10−4pb−1. Sleptons can be also single produced in gaugino decays at large hadron colliders. Relatively light sleptons may be observable in these processes in specific models.
