The authors' main claim Surprisingly, as a result of the merging of two branches of the solution - one originating at zero tachyon vev and the other originating at the tachyonic vacuum - this effective potential exists only for a finite range of values of the massless field.

We use the level truncation scheme to obtain accurate descriptions of open bosonic string field configurations corresponding to large marginal deformations such as background Wilson lines. To do so, we solve for all fields as functions of the massless string field, and confirm that the effective potential of the massless field becomes increasingly flat as the level of approximation is increased. Surprisingly, as a result of the merging of two branches of the solution - one originating at zero tachyon vev and the other originating at the tachyonic vacuum - this effective potential exists only for a finite range of values of the massless field. We use the D1 to D0 brane marginal transition on a circle to explore the possibility that this finite range corresponds to the infinite range of the conformal field theory parameter describing marginal deformations, but are unable to arrive at a definitive conclusion.

We use the level truncation scheme to obtain accurate descriptions of open bosonic string field configurations corresponding to large marginal deformations such as background Wilson lines. To do so, we solve for all fields as functions of the massless string field, and confirm that the effective potential of the massless field becomes increasingly flat as the level of approximation is increased. Surprisingly, as a result of the merging of two branches of the solution - one originating at zero tachyon vev and the other originating at the tachyonic vacuum - this effective potential exists only for a finite range of values of the massless field. We use the D1 to D0 brane marginal transition on a circle to explore the possibility that this finite range corresponds to the infinite range of the conformal field theory parameter describing marginal deformations, but are unable to arrive at a definitive conclusion.

In string field theory such solutions can be obtained perturbatively in the marginal deformation parameter.[For nonperturbative approach to marginal deformations see [ref] .] Recently such solutions, exact to all orders, have been found [ref] in the very convenient $_0$-gauge of [ref] .[Other gauges for OSFT were recently considered in [ref] .] Generalizations and related work can be found in [ref] .

Ever since the analytic solution for tachyon condensation in open bosonic string field theory [ref] was constructed by Schnabl [ref] , new analytic technologies have been developed [ref] , and analytic solutions for marginal deformations were recently constructed [ref] .[ For earlier study of marginal deformations in string field theory and related work, see [ref] . ] We believe that we are now in a new phase of research on open string field theory.[ See [ref] for reviews.]
