I have a couple of questions about the standard model:
1.) I read somewhere that the standard model describes 3 closely related Yang-Mills systems, but i thought yang-mills systems were non-abelian whereas U(1) is abelian. So is the statement false or have i misunderstood?
2.)Why do i see subscripts for the gauge symettries of SU(3)xSU(2)xU(1) and they are soemtimes different depending where i read from. Can anyone guide me on this please?
Many thanks
