Abstract
The phase diagram of the two-channel Kondo lattice model is examined w ith a quantum Monte Carlo simulation in the limit of infinite dimensio ns. Commensurate (and incommensurate) antiferromagnetic and supercondu cting states are found. The antiferromagnetic transition is very weak and continuous. The superconducting transition is discontinuous to an odd-frequency channel-singlet and spin-singlet pairing state.
