FIZIKA B 5 (1996) 3, 159166 DIRAC EQUATION WITH TWO MASS PARAMETERSANDREA RASPINI Received 5 September 1996The Dirac equation is modified in order to allow for two mass parameters (called m_{R} and m_{L}). The massless case is especially interesting and is obtained when the product of the two mass parameters is null. In particular, the physical neutrino current can be derived in a more consistent manner than usual. Some possible applications are discussed. UDC 530.145
