Introduction to Superstring Theory I

Carlo Angelantonj - University of Torino, Torino

  The aim of the course is to provide a brief introduction to the construction of consistent (super)string vacua in D=26 (D=10). Toroidal and orbifold compactifications as well as D-branes will be discussed. The plan of the lectures is:
    1. Light-cone quantisation of the bosonic string. The one-loop partition function for closed strings.
    2. Circle compactification: T-duality and gauge symmetry enhancement.
    3. Orbifold compactifications.
    4. Light-cone quantisation of the fermionic string. The consistency of the one-loop partition function for closed strings. Type IIA/IIB and heterotic strings in D=10.
    5. D-branes and orientifold constructions.
