The Lorentz-invariant boundary action of the confining string and its universal contribution to the inter-quark potential

M. Billo, M. Caselle, F. Gliozzi +2

We study the boundary contribution to the low energy effective action of the open string describing the confining flux tube in gauge theories. The form of the boundary terms is str…
