Some computations of partition functions and tachyon potentials in background independent offshell string theory
Abstract
We discuss what information can be safely extracted from background independent offshell string theory. The major obstacle in doing so is that renormalization conditions of the underlying worldsheet theories are not exactly known. To get some insight, we first consider the tachyon and gauge field backgrounds and carry out computations in different renormalization schemes for both, bosonic string and superstring. Next, we use a principle of universality (renormalization scheme independence) to somehow compensate the missing of the renormalization conditions and get information we are looking for. It turns out that some asymptotics which are responsible for the potentials only obey the principle of universality.
