Hi there - does anyone know a good reference in which it is shown that we can derive QED from the Weinberg-Salam model? (Or if we can't, does anyone know why?) Thanks!
 
The original papers show this. Any textbook, like Griffiths, will show this.

I am intrigued: How do you failed to find the reference -even the wikipedia does a decent work-, or to infer that we can not?
