Description
We present an action for the dynamical system of N nearly coincident multiple D0-branes and strings connecting these D0-branes (mD0 system) which is invariant under spacetime (type IIA target superspace) supersymmetry and the local worldline supersymmetry generalizing the kappa-symmetry of single D0-brane action (massive D=10 superparticle or Dirichlet superparticle). The action includes an arbitrary nonvanishing function M(H) of the relative motion Hamiltonian H. The 10D mD0 model with a particular form of M(H) can be obtained by dimensional reduction from the action of the D=11 multiple M-wave (mM0) system. This talk is based on Phys. Rev. D106 (2022) 066004 with Igor Bandos.
