Summary
We continue to carry out the programme of covariant quantisation, this time with emphasis on the massless closed string states: the graviton, the Kalb–Ramond or B-field, and the dilaton. The graviton is related to the linearised Einstein equations, the Kalb–Ramond field is used to discuss the properties and the dualisation of higher rank gauge fields, the dilaton serves as a first example of a ‘moduli field’ and its relation to the string coupling is explained.
