DESCRIPTION:CP violation was first discovered in kaon decay fifty years ag
 o. If the parameters of direct and indirect CP violation are very well-mea
 sured experimentally\,  a\ncomplete and quantitative theoretical computati
 on is still missing.\nHowever\, thanks to numerical simulations of lattice
  QCD\,\nan important contribution has been computed two years ago: the amp
 litude of a kaon to decay into two pions with Isospin two. I will present 
 this work with emphasis on the challenges and on the theoretical ideas\nwh
 ich made this computation possible. Then I will present the progress we ha
 ve made on the other part of the computation\, where the two-pion state ha
 s isospin zero. From these computations\, a tentative explanation of the "
 Delta I = 1/2 rule" will be given. Finally in the last part of the seminar
  I will present our work on neutral kaon mixing (within and beyond the sta
 ndard model) and give an overview of the situation.
