Scientific paper

Thermal leptogenesis is an attractive mechanism for generating the baryon
asymmetry of the Universe. However, in supersymmetric models, the parameter
space is severely restricted by the gravitino bound on the reheat temperature
$T_{RH}$. Using a parametrisation of the seesaw in terms of weak-scale inputs,
the low-energy footprints of thermal leptogenesis are discussed.
