Using S(pacelike)-branes defined through rolling tachyon solutions, we show how the dynamical formation of D(irichlet)-branes and strings in tachyon condensation can be understood. Specifically we present solutions of S-brane actions illustrating the classical confinement of electric and magnetic flux into fundamental strings and D-branes. The role of S-branes in string theory is further clarified and their RR charges are discussed. In addition, by examining "boosted" S-branes, we find what appears to be a surprising dual S-brane description of strings and D-branes, which also indicates that the critical electric field can be considered as a self-dual point in string theory. We also introduce new tachyonic S-branes as Euclidean counterparts to non-BPS branes.

“…The generalization of Sen's action to include tachyonic couplings in a (Dp,Dp) system [18,19,20,21,22,23,24,25,26,7,27,28,29,30] describes, to second order in α ′ , an Abelian Higgs model in which the Abelian field is the relative BI vector of the brane and the antibrane and the phase of the tachyon plays the role of the associated Goldstone boson. We will show however that the dual of this action does not describe an Abelian Higgs model for the relative (p − 2)-form potential, contrary to the expectation in [15].…”

“…The effective action describing a brane-antibrane pair has been extensively studied in the literature using different approaches [18,19,20,21,22,23,24,25,26,7,27,28,29,30]. Although the complete action has not been derived from first principles it is known to satisfy a set of consistency conditions [7].…”

“…We will also ignore the tachyonic couplings to the C p−1 RR-potential derived in [19,21,29]. Thus, our action represents a truncated version of the (Dp,Dp) action that can be derived from the results in [18,19,20,21,22,23,24,25,26,7,27,28,29,30] 8 . We will see however that it contains the relevant couplings for describing the most important aspects of the dynamics of the (Dp,Dp) system, both in the Higgs and in the confining phases 9 .…”

“…Note that in comparing with the boundary string field theory results [39] there is the usual discrepancy by 2 log 2 in the kinetic term of the tachyon [21,22,26]. 9 Once it is extended as we do in next section in order to incorporate the non-perturbative degrees of freedom associated to the (p − 3)-brane topological defects.…”

We present a worldvolume effective action suitable for the study of the confined phase of a (Dp,Dp) system at weak coupling. We identify the mechanism by which the fundamental string arises from this action as a confined electric flux string when the Dp and theDp annihilate. We construct an explicit dual action, more suitable for the study of the strong coupling regime, and show that it realizes a generalized Higgs-Stückelberg phase for the (relative) (p − 2)-form field dual to the (overall) BI vector. This is the mechanism put forward by Yi and collaborators based on duality arguments in order to explain the breaking of the overall U (1) gauge group at strong coupling. Indeed, in our dual description the Goldstone boson is a (p − 3)-form magnetically charged with respect to the overall BI vector field. This indicates that the condensing tachyonic objects originate from open D(p − 2)-branes stretched between the brane and the anti-brane. Our results provide an explicit realization of the breaking of the overall U (1) gauge group perturbatively, in a way consistent with the duality symmetries of String Theory.

Brane inflation is a specific realization of the inflationary universe scenario in the early universe within the brane world framework in string theory. The naturalness and robustness of this realistic scenario is explained. Its predictions on the cosmological observables in the cosmic microwave background radiation, especially possible distinct stringy features, such as large non-Gaussianity or large tensor mode that deviates from that predicted in the slow roll scenario, are discussed. Stringy KK modes as hidden dark matter is also a possibility. Another generic consequence of brane inflation is the production of cosmic strings towards the end of inflation. These cosmic strings are nothing but superstrings stretched to cosmological sizes. The properties of these cosmic superstrings and their subsequent cosmological evolution into a scaling network open up their possible detections in the near future, via cosmological, astronomical and/or gravitational wave measurements. At the moment, cosmological data is already imposing strong constraints on the details of the scenario. Finding distinctive stringy signatures in cosmological observations will go a long way in revealing the specific brane inflationary scenario and validating string theory as well as the brane world picture. Precision measurements may even reveal the structures of the flux compactification. Irrespective of the final outcome, we see that string theory is confronting data and making predictions.In celebration of the 65th birthday of Gabriele Veneziano, teacher and friend. *
