Maccaferri, Carlo20052011-09-0720052011-09-072005JHEP 0509 (2005) 022https://openscience.sissa.it/handle/1963/1748We give a description of open strings stretched between N parallel D-branes in VSFT. We show how higgsing is generated as the branes are displaced: the shift in the mass formula for on-shell states stretched between different branes is due to a twist anomaly, a contribution localized at the midpoint.225161 bytesapplication/pdfen-USPreprint
