在LHC上发现超对称性的前景

Prospects for Discovering Supersymmetry at the LHC

John Ellis

摘要:

超对称性是可能在大型强子对撞机上发现的、超越标准模型的最有动机的物理学候选者之一。有很多理由可以期待它可能出现在TeV尺度上,特别是因为它提供了一个天然的冷暗物质候选者。g_mu - 2的实验测量值与使用低能e+ e-数据计算的标准模型值之间的明显差异有利于LHC获得相对较轻的s粒子。一个包括这个、其他电弱精密观测值和B衰变观测值的全局似然分析表明,LHC可能能够发现具有1/fb或更少积分亮度的超对称性。大型强子对撞机应该能够通过经典的丢失能量特征或替代的唯象场景来发现超对称性。在大型强子对撞机上发现超对称性的前景看起来非常好。

英文摘要:

Supersymmetry is one of the best-motivated candidates for physics beyond the Standard Model that might be discovered at the LHC. There are many reasons to expect that it may appear at the TeV scale, in particular because it provides a natural cold dark matter candidate. The apparent discrepancy between the experimental measurement of g_mu - 2 and the Standard model value calculated using low-energy e+ e- data favours relatively light sparticles accessible to the LHC. A global likelihood analysis including this, other electroweak precision observables and B-decay observables suggests that the LHC might be able to discover supersymmetry with 1/fb or less of integrated luminosity. The LHC should be able to discover supersymmetry via the classic missing-energy signature, or in alternative phenomenological scenarios. The prospects for discovering supersymmetry at the LHC look very good.
