Hi,guys. Where can I get some animated carton of particle collision.? It is better a gif file and I want insert it into a ppt file. There are some animations in LHC homepage, but they are too large.

I always hear that the "global fit" EW precision test. It seems that I understand it a little. But I am still very clear. Who can shed light on it?

The coupling of gauge bosons self interaction in non-abelian gauge theory is proportional to f_{abc}, i.e. only diffrent bosons can interact. So, no Z-Z-A and no Z-Z-Z interactions. You can also think that photon only couple to charged particles directly.

Yes, it is indeed very convieient. It may be because we are too affected by microsoft.

what is the most convenient Feynman diagram drawing tool? I have only grasped the method drawing feynman diagrams by usual Tex command as drawing other diagrams. For example "\ArrowLine(40.0,150.0)(90.0,150.0) ". But is very clumsy. Do you know other convenient Feyman drawing tool? I hear that...
