We construct a general map between a Dp-brane with magnetic flux and a matrix configuration of D0-branes, by showing how one can rewrite the boundary state of the Dp-brane in terms of its D0-brane constituents. This map gives a simple…
Bounds on the anomalous magnetic moment and the electric dipole moment of the $\tau$-neutrino are calculated through the reaction $e^{+}e^{-}\to \nu \bar \nu \gamma$ at the $Z_1$-pole, and in the framework of a left-right symmetric model.…

We examine the application of boundary states in computing amplitudes in off-shell open string theory. We find a straightforward generalization of boundary state which produces the correct matrix elements with on-shell closed string states.
The energy levels, generally known as the Landau levels, which characterize the motion of an electron in a constant magnetic field, are those of the one-dimensional harmonic oscillator, with each level being infinitely degenerate. We show…
