We study the formation of D and F cosmic strings in D-brane annihilation after brane inflation. We show that D string formation by quantum de Sitter fluctuations is severely suppressed, due to suppression of RR field fluctuations in compact dimensions. We discuss the resonant mechanism of production of D and F strings, which are formed as magnetic and electric flux tubes of the two orthogonal gauge fields living on the world-volume of the unstable brane. We outline the subsequent cosmological evolution of the D−F string network. We also compare the nature of these strings with the ordinary cosmic strings and point out some differences and similarities.

Cosmological evolution of cosmic string loops (2005, background): “Recently, cosmic strings have been of particular interest since it was pointed out that Fundamental and Dirichlet strings formed at the end of brane inflation could also play a cosmic string-like role in cosmology [6]–[8].”

Inflation and String Theory (2014, background): “In particular, a colliding pair of strings can miss each other in the compact dimensions [597, 600, 602], and the string coupling gs also suppresses the intercommutation probability.”

Challenges and opportunities of gravitational-wave searches at MHz to GHz frequencies (2020, background): “from string theory, formed for instance at the end of brane inflation [208, 209], and stretched to cosmological scales.”
Cosmic F- and D-strings (2003, methodology): “While we were completing this work we learned of papers on related subjects by Dvali, Kallosh and Van Proeyen [12] and by Dvali and Vilenkin [13].”
Collisions of cosmic F- and D-strings (2004, background): “These can be produced after inflation [2-7], and in some models they are stable or at least metastable on cosmic time scales [8, 9].”
Beyond the Standard Models with cosmic strings (2019, background): “cal simulations [72] and analytical modelling [73], the probability of inter-commutation has been found to be P= 1 but in some models it can be lower. This is the case of models with extra-dimensions [59,74], strings with junctions [75] or peeling [76], or the case of highly relativistic strings [77”
