标题： Supersymmetric Lepton Flavour Violation at the LHC and LC

摘要： 在标准模型的超对称扩展中，重中微子的Yukawa和/或质量项可以生成轻子味违反的slepton质量项。这些新的超对称轻子味违反来源可能会增强带电轻子味违反过程l_a -> l_b y的速率，并在未来的对撞机上产生不同的末态，如l_b l_a + jets + 缺失E_T。首先，我们讨论未来e^+e^-对撞机对SLFV的敏感性，独立于轻子味违反机制。其次，我们在mSUGRA在LEP之后的基准场景中的 seesaw 机制背景下，研究未来e^+e^-直线对撞机上的轻子味违反slepton对产生和衰变。我们研究了这些信号与相应的轻子味违反稀有衰变l_a -> l_b y的相关性，并表明这些相关性特别适合于探究轻子味违反的起源。 显示英文摘要

摘要： In supersymmetric extensions of the Standard Model, the Yukawa and/or mass terms of the heavy neutrinos can generate lepton flavour violating slepton mass terms. These new supersymmetric sources of lepton flavour violation may both enhance the rates of charged lepton flavour violating processes, l_a -> l_b y, and generate distinct final states, like l_b l_a + jets + missing E_T, at future colliders. First, we discuss the sensitivity of future e^+e^- colliders to the SLFV independently of the lepton flavour violating mechanism. Second, we study lepton flavour violating slepton pair production and decay at a future e^+e^- linear collider in the context of the seesaw mechanism in mSUGRA post-LEP benchmark scenarios. We investigate the correlations of these signals with the corresponding lepton flavour violating rare decays l_a -> l_b y, and show that these correlations are particularly suited for probing the origin of lepton flavour violation.
