New physics seen?

Posted by Phiphy on 03/06/2008

The UTfit group claimed that they find the ‘first evidence’ of new physics in b-s transition.By combining analysis of all the experiments on B_s mixing, the CP violation phase is 3\sigma deviated from both SM and MFV(minimum flavor violation). Sounds thrilling, but we still need to wait and see.

LHC failure

Posted by Phiphy on 04/04/2007

This title is a bit exaggerating. Actually, it was the magnet that failed and was damaged. See here.

I just learned a little thing about the structure of general accelerators yesterday. Experimental physics is tough, at least for me. It is too complicated and serious due to the close relationship with reality. Physics is dealing with reality, but I would like those simple things behind reality rather than reality itself. That’s why I choose theoretical physics.

Best wishes to LHC. The whole world is waiting for you. I am not. I have learned too little to ride on the tide. I am just going with my own pace.
