Kalb–Ramond field

The adjective "NS" reflects the fact that in the

The Kalb–Ramond field generalizes the

${\displaystyle -q\int dx^{\mu }A_{\mu }}$

that for a string coupled to the Kalb–Ramond field has the form

${\displaystyle -\int dx^{\mu }dx^{\nu }B_{\mu \nu }}$

This term in the action implies that the fundamental string of string theory is a source of the NS–NS B-field, much like charged particles are sources of the electromagnetic field.

The Kalb–Ramond field appears, together with the
