Sliver frame stubs in OSFT via auxiliary fields
arXiv:2410.16228 · doi:10.1103/PhysRevD.111.106019
Abstract
In this short paper we want to generalize some recent concepts related to stubs in open string field theory. First, we modify the auxiliary field method by Erbin and Firat [#Erbin2023] to non-BPZ even sliver frame stubs. We then also show that the construction is consistent at the full quantum level without any additional assumptions. Finally, we apply the method explicitly to the tachyon vacuum and the simplest identity-like solution.
