    "abstract": "Reformulation of Dirac equation in terms of real quadratic division algebra\nof quaternions is given. Similar equations with different mass term are\nidentified as suitable for description of free propagating quark motion. The\ncomplete orthonormal set of the positive-energy plane wave solutions is\npresented. Therefore, Zitterbewegung phenomenon is absent in this formulation.\nThe probability current is proportional to the momentum, as in standard\nSchrodinger wave mechanics.",
