A Lightning Introduction to String Theory
arXiv:2406.09508 · doi:10.1007/978-981-19-3079-9_53-1
Abstract
We give a lightning introduction to critical string theory, including the 26-dimensional bosonic string, the 10-dimensional superstrings and heterotic strings with and without spacetime supersymmetry. We also discuss open strings and D-branes, as well as the orientifold constructions, in ten dimensions.
