Lorentz invariance and elementary particle properties

The properties of elementary particles are investigated at fulfilment of two principal conditions: existence of the invariant Lagrange function and a complete description of the energy limit E→infinity. It is proved that a cosmological term should be introduced in Einstein equations. It is shown that neutrino-type particles with helicities -1, +1, -2, +2 in the Minkowsky space are confined. They do not exist in a free state. In spaces with metrices (++++) and (++--) the confinement is absent
