Abstract
Understanding the extent to which experimental searches are sensitive to scenarios involving Light Stops (LST) is essential to resolve questions about naturalness, electroweak baryo-genesis and Dark Matter. In this chapter, the reach on LST scenarios is characterised in two ways. Firstly, we extend experimental searches to cover specific gaps in the LST parameter space, showing for the first time that assuming a single decay channel one can exclude the region of \(m_{\tilde{t}} < m_{top}\), which in its turn excludes electroweak baryogenesis in MSSM. Secondly, we explore the extent to which searches are weakened in a more generic scenario when more than one decay channel takes place, even after their combination. This work highlights the need for a more comprehensive exploration of the LST parameter space.
