Angular Dependence of the Upper Critical Field in Triplet   Quasi-one-dimensional Superconductors at High Magnetic Fields
  Assuming that the order parameter corresponds to an equal spin triplet pairing state, we calculate the angular dependence of the upper critical field in triplet quasi-one-dimensional superconductors at high magnetic fields applied alongthe yz plane
