The mass-extended 't Hooft-Nobbenhuis complex transformations and their consequences

We have extended the 't Hooft-Nobbenhuis complex transformations to include mass. Under these new transformations, Schrödinger, Dirac, Klein-Gordon and Einstein generalrelativity equations are invariant. The non-invariance of the cosmological constant in Einstein field equations dictates it to vanish thus solving the long-standing cosmological-constant problem.
