Nambu-Goto String Without Tachyons Between a Heavy and a Light Quark
Abstract
We point out that the singularity in the interquark potential at small distances disappears in infinite space-time dimensions if a Nambu-Goto string is anchored at one end to an infinitely heavy quark and at the other to an infinitely light quark. This suggests that, if such quarks are placed at the ends of the string, some unphysical features such as tachyon states in the string spectrum are absent also in finite dimensions.
