Abstract

I will develop a bottom-up approach to studying SUSY with light stops and sbottoms, but with other squarks and sleptons beyond reach of the LHC. I will discuss the range of squark, gaugino and Higgsino masses for which the electroweak scale is radiatively stable over the ``little hierarchy'' below 10 TeV. I will review and expand on indirect constraints on this scenario. I will discuss phenomenological differences between Majorana and Dirac gauginos and argue that in this context, R-parity violation is very well motivated. Finally, I will focus on the light subsystem of stops, sbottom and neutralino with R-parity, in order to probe the current collider bounds.
