Within my project thesis I stumbled over the term SU(2)_V, SU(2)_A transformations. Although I know U(1)_V, U(1)_A transformations from the left and right handed quarks( U(1)_V transformations transform left and right handed quarks the same way, while U(1)_A transformations transform them with a phase which just differs by a minus sign) I have no idea what vectorial /axial stands for in the SU(2) context.(adsbygoogle = window.adsbygoogle || []).push({});

Thank you again so much in advance,

Bob
