Field Theoretic Branes and Tachyons of the QCD String
- SLAC
Dvali and Shifman have proposed a field-theoretic mechanism for localizing gauge fields to ''branes'' in higher dimensional spaces using confinement in a bulk gauge theory. The resulting objects have a number of qualitative features in common with string theory D-branes; they support a gauge field and flux strings can end on them. In this letter, we explore this analogy further, by considering what happens when N of these ''branes'' approach each other. Unlike in the case of D-branes, we find a reduction of the gauge symmetry as the ''branes'' overlap. This can be attributed to a tachyonic instability of the flux string stretching between the branes.
