As I understand it string theory says that charged particles like electrons and quarks are actually open strings whose endpoints interact with the electromagnetic field $A_\mu$.

String theory also says that the bulk of these open strings interact with the Kalb-Ramond field $B_{\mu\nu}$.

So is a charged particle a source for both fields $A_\mu$ and $B_{\mu\nu}$?

Could we detect the $B_{\mu\nu}$ field using charged particles?
