Rotating strings with B-field

Some of the recent important developments in understanding string/ gauge dualities are based on the idea of highly symmetric motion of 'string solitons' in AdS5 x S5 geometry originally suggested by Gubser, Klebanov and Polyakov. In this paper we study symmetric motion of short strings in the presence of antisymmetric closed string B-field. We compare the values of the energy and the spin in the case of non-vanishing B-field with those obtained in the case of B = 0. The presence of Neveu-Schwarz-Neveu-Schwarz (NS-NS) antisymmetric field couples the fluctuation modes that indicates changes in the quantum corrections to the energy spectrum. (authors)
