1301.3437 (Marco Meineri)

Lorentz completion of effective string action    [PDF]

Marco Meineri
In the presence of a confining flux tube between a pair of sources the vacuum is no longer Poincar\'e invariant. This symmetry is nonlinearly realized in the effective string action. A general method for finding a large class of Lorentz invariant contributions to the action is described. The relationship between this symmetry and diffeomorphism invariance is further investigated.
