Interactions of non-Abelian global strings

摘要: Abstract Non-Abelian global strings are expected to form during the chiral phase transition. They have orientational zero modes in internal space, associated with vector-like symmetry SU ( N ) L + R broken presence of strings. The interaction among two parallel non-Abelian is derived for general relative modes, giving a generalization Magnus force. It shown that when orientations same, repulsive force reaches maximum, whereas orientation becomes no exists between For Abelian case we find finite volume correction known result. marginal instability previously η ′ discussed.
