Phys. Rev. D 52, 1011–1018 (1995)Mass eigenvalues of the open charged string in a magnetic backgroundReceived 10 February 1995; published in the issue dated 15 July 1995 The quantum theory of an open charged bosonic string in a magnetic background is considered. The squared mass operator is found and the mass spectrum analyzed. The spin-one spectrum manifests a peculiar behavior in the presence of the background field. One of the spin-one states is a tachyon at any nonzero field strength, while the other can be massive or tachyonic depending on the strength of the background magnetic field. © 1995 The American Physical Society URL:
