" It is usually assumed that new physics associated with EWSB is flavor blind, so that, for example, its couplings to electrons and muons are identical. Is this necessarily the case? How are searches and analysis techniques affected if the new physics is flavor-dependent? How can we measure this flavor dependence and what can we learn from it? I will use the sleptons of supersymmetry as an example to illustrate these questions. In the first lecture, I will introduce the basics of flavor violation in the slepton sector, and argue that the sleptons could naturally have generation-dependent masses and mixings, which satisfy all low-energy bounds yet are large enough to affect the slepton signatures at colliders. I will discuss the implications for both missing-energy, and meta-stable slepton NLSP scenarios. In the second lecture, we will start exploring methods for mass and mixing measurements, in the context of a meta-stable slepton NLSP. In particular, since quasi-degenerate particles will generically occur if flavor-dependent scenarios, I will talk about how we can detect such particles and measure their mass differences. "
