%0 Journal Article %T D-particle creation on an orientifold plane %A Yosuke Imamura %J Physics %D 1997 %I arXiv %R 10.1016/S0370-2693(97)01481-0 %X We study the propagations of gravitational wave and D-particle on D6-brane and orientifold 6-plane backgrounds in the M-theory framework. In the case of orientifold plane, D-particle number is not conserved and gravitational wave can convert into D-particle. For the simplest case, we calculate its amplitude numerically. %U http://arxiv.org/abs/hep-th/9710026v3
