Hi guys,
Everyone knows that one can calculate the S-Matrix with various tricks. One of them is to use traces to simplify the matrices.
Can someone tell me or point me to a place where I can find an explanation why I can do this?
I think I vaguely remember that I have seen once an equation showing why traces can be used, but I can't recall that source (book? lecture notes? websites?)
Thanks
