Hello Everyone, Hope you are all enjoying learning more and more about this wonderful world of Physics! Is it that I am missing something somewhere, but when I searched the ATLAS site to find out what experiments were planned to measure the self-interaction of the Higgs, I could see nothing! It all seems to be about verifying supersymmetry and other new theories. One would think that knowing the self-interaction of the Higgs would signal new physics definitely if it were different from that which is predicted. It would be good to hear from a senior academic on this. Best wishes and keep on exploring the frontiers!
