I'm having some troubles understanding the unit used in solid state physics. In a paper I read \Lambda a \sim 1 where \Lambda is a momentum cutoff and a is the lattice spacing of a crystal. Questions: 1) What kind of units are customarily used in solid state physics scientific...

I'm not an expert in this field, however... Maybe it should be clearer if I say that the initial and final states of a scattering process must be color neutral; during the scattering process the quarks can mix up, as the are confined pratically in the same place. Then they can split, to the...

This is due to color confinement... The color forces don't let a color-charged particle to live "isolated"... A proton has a neutral color charge, and the mesons all have a neutral color charge, as they are formed by a colored quark, and it's anticolor. (e.g. red + antired). (Btw it's not a...
