Equations of the twistor formulation are obtained for massive and massless spinning particles. The twistor space of the massive particle is formed by two twistors and two complex scalars. In the massive case, integral transformations relating twistor fields with usual space-time fields have been constructed.6 pages, Contribution to the Proceedings of the International Workshop "Supersymmetry and Quantum Symmetries" (SQS'03, Dubna, 34-29 July 2003), v2 typos correctedHigh Energy Physics - Theorytext
