Cosmic Dstrings as axionic Dterm strings
Abstract
In this work we derive nonsingular BPS string solutions from an action that captures the essential features of a DbraneantiDbrane system compactified to four dimensions. The model we consider is a supersymmetric Abelian Higgs model with a Dterm potential coupled to an axiondilaton multiplet. The strings in question are axionic Dterm strings which we identify with the Dstrings of type II string theory. In this picture the Higgs field represents the open string tachyon of the DD pair and the axion is dual to a RamondRamond form. The crucial term allowing the existence of nonsingular BPS strings is the FayetIliopoulos term, which is related to the tensions of the Dstring and of the parent branes. Despite the presence of the axion, the strings are BPS and carry finite energy, due to the fact that the space gets very slowly decompactified away from the core, screening the long range axion field (or equivalently the theory approaches an infinitely weak 4D coupling). Within our 4D effective action we also identify another class of BPS string solutions (sstrings) which have no tendimensional analog, and can only exist after compactification.

We investigate the stability of a new class of BPS cosmic strings in N=1 supergravity with Dterms recently proposed by BlancoPillado, Dvali and Redi. These have been conjectured to be the low energy manifestation of Dstrings that might form from tachyon condensation after D antiDbrane annihilation in type IIB superstring theory. There are three oneparameter families of cylindrically symmetric onevortex solutions to the BPS equations (tachyonic, axionic and hybrid). We find evidence that the zero mode in the axionic case, or sstrings, can be excited. Its evolution leads to the decompactification of fourdimensional spacetime at late times, with a ratemore »

Compact threedimensional QED with a {theta} term and axionic confining strings
We discuss threedimensional compact QED with a {theta} term due to an axionic field. The variational gaugeinvariant functional is considered and it is shown that the groundstate energy is independent of {theta} in a leading approximation. The mass gap of the axionic field is found to be dependent upon {theta}, the mass gap of the photon field, and the scalar potential. The vacuum expectation of the Wilson loop is shown to be independent of {theta} in a leading approximation, to obey the area law, and to lead to confinement. We also briefly discuss the properties of axionic confining strings. {copyright}more » 
Hiding cosmic strings in supergravity Dterm inflation
The influence of higherorder terms in the Kaehler potential of the supergravity Dterm inflation model on the density perturbation is studied. We show that these terms can make the inflaton potential flatter, which lowers the energy scale of inflation under the COBE/WMAP normalization. As a result, the mass per unit length of cosmic strings, which are produced at the end of inflation, can be reduced to a harmless but detectable level without introducing a tiny Yukawa coupling. Our scenario can naturally be implemented in models with a low cutoff as in Type I or Type IIB orientifold models. 
Cosmic D and DFstrings from D3D3: Black strings and BPS limit
We study D and DFstrings in a D3D3 system by using DiracBornInfeld type action. In the presence of an electric flux from the transverse direction, we discuss gravitating thick Dstring solutions of a spatial manifold, S{sup 2}xR{sup 1}, in which straight Dstrings stretched along the R{sup 1} direction are attached to the south and north poles of the twosphere. There is a horizon along its equator, which means the structure of black strings is formed. We also discuss the BPS limit for thin parallel D and DFstrings in both flat and curved spacetime. We obtain the BPS sum rule formore » 
Axionic black holes and an AharonovBohm effect for strings
It is shown that a black hole of fixed mass can carry arbitrary axionic charge. The unique static blackhole solution is found to have vanishing axion field strength but nonvanishing potential. The axion charge cannot be detected by point particles, but can be detected by strings in a process analogous to the AharonovBohm effect. It is argued that the existence of axion charge may play a significant role in the late stages of blackhole evaporation.
