Open superstring partition function in a constant gauge field background at finite temperature Original Research Article

We find the general expression for the open superstring partition function on the annulus in a constant abelian gauge field background and at finite temperature. We use the approach based on the Green-Schwarz string path integral in the light-cone gauge and compare it with the NSR approach. We discuss the super Yang-Mills theory limit of the string free energy and mention some D-brane applications.
