Description

I will review the status of confining strings as observed in the lattice simulations of SU(N) YangMills theory. The currently observed states are all well described by the low energy effective theory of a long string consisting of two translational Goldstone bosons ("phonons"), along with a massive pseudoscalar ("the worldsheet axion") coupled to phonons through a worldsheet theta-term. Moreover, the leading axion-axion and axion-phonon interactions are well approximated by the TTbar deformation of a free axion.
