Hi all

what is meant isospin asymmetry for nuclear matter ?

thanks a lot

hi lamyaa!

"Isospin [symmetry] is violated by the fact that the masses of the up and down quarks are different, as well as by their different electric charges.
Because this violation is only a small effect in most processes that involve the strong interactions, isospin symmetry remains a useful calculational tool, and its violation introduces corrections to the isospin-symmetric results."
