Hi there, I'm searching for an argument according to which fundamental strings cannot carry RR charge. I'm aware of the couplings between, say, the Maxwell field and the point particle, the string and the B_{\mu\nu}, and the D-branes and the various RR potentials.
One should form Lorentz scalars, right? But why can't a string couple to a C_{\mu\nu} RR potential? Thank you in advance!
