Strings, Branes and Extra Dimensions
Lykken, Joseph D, Gusber, Steven S · 2004
This review is devoted to strings and branes.Firstly, perturbative string theory is introduced.The appearance of various types of branes is discussed.These include orbifold fixed planes, D-branes and orientifold planes.The connection to BPS vacua of supergravity is presented afterwards.As applications, we outline the role of branes in string dualities, field theory dualities, the AdS/CFT correspondence and scenarios where the string scale is at a TeV.Some issues of warped compactifications are also addressed.These comprise corrections to gravitational interactions as well as the cosmological constant problem.
