Cosmic string production towards the end of brane inflation

摘要: Abstract Towards the end of brane inflationary epoch in world, cosmic strings (but not texture, domain walls or monopoles) are copiously produced during collision. These Dp-branes with (p−1) dimensions compactified. We elaborate on this prediction superstring theory description world. Using data temperature anisotropy microwave background, we estimate string tension μ to be around Gμ≃10−7. This turn implies that background comes mostly from inflation, but a component (of order 10%) strings. effect should also observable gravitational wave detectors and maybe even pulsar timing measurements.
