As I understand it all string theories have the following bosonic fields: the metric ##G_{\mu\nu}##, the Kalb-Ramond gauge field ##B_{\mu\nu}## and the dilaton field ##\Phi##.
Is it true that the electromagnetic field arises from components of the Kalb-Ramond field ##B_{\mu\nu}## where ##\mu## is one of the large dimensions of 4D spacetime and ##\nu## is one of the compactified dimensions?
