On gauge bosons in the matrix model approach to M theory
Abstract
We discuss the appearance of E_{8} × E_{8} gauge bosons in Banks, Fischler, Shenker, and Susskind's zero brane quantum mechanics approach to M theory, compactified on the interval S^{1}/Z_{2}. The necessary bound states of zero branes are proven to exist by a straightforward application of Tduality and heterotic Spin(32)/Z_{2}Type I duality. We then study directly the zero brane Hamiltonian in Type I' theory. This Hamiltonian includes couplings between the zero branes and background Dirichlet 8 branes localized at the orientifold planes. We identify states, localized at the orientifold planes, with the requisite gauge boson quantum numbers. An interesting feature is that E_{8} gauge symmetry relates bound states of different numbers of zero branes.
