Magnetic fields produced in collisions of electrically charged particles at
relativistic energies are strong enough to affect the dynamics of the strong
interactions. In particular, it induces radiation of vector bosons by
relativistic fermions. To develop deeper insight into this problem, I calculate
the corresponding spectrum in constant magnetic field and analyze its angular
distribution and mass dependence. As an application, I consider synchrotron
radiation of virtual photon by the quark-gluon plasma.Comment: 13 pages, 6 figure
