Explaining matter/antimatter asymmetries
... There is much at stake. Despite many attempts, no one has been able to use the KM model of CP violation to create the matter excess of the universe through Sakharov's mechanism. Only a small asymmetry is needed in the early universe, since today we have only one leftover proton for each billion phot ...

Introduction to Supersymmetry
... like e2/a (a → 0), i.e., it is linearly divergent. In quantum theory, fluctuations of the electromagnetic fields (in the “single electron theory”) generate a quadratic divergence. If these divergences are not canceled, one would expect that QED should break down at an energy of order me/e far below th ...
