Flavour constraints on scenarios with two or three heavy squark generations

Understand

We re-assess constraints from flavour-changing neutral currents in the kaon system on supersymmetric scenarios with a light gluino, two heavy generations of squarks and a lighter third generation.

• We compute for the first time limits in scenarios with three heavy squark families, taking into account QCD corrections at the next-to-leading order.
• We compare our limits with those in the case of two heavy families.
• We use the mass insertion approximation and consider contributions from gluino exchange to constrain the mixing between the first and second squark generation.
