The characteristic property of the 2-d Polyakov action is its independence on
the metric tensor, without being topological. A renormalizable 4-d action is
found with this fundamental property. It is invariant under the
pseudo-conformal transformations and it contains a gauge field instead of the
scalar field (the embedding function to the ambient 26-d spacetime) of the
string action. The fundamental quantity of this pseudo-conformal field theory
(PCFT) is the lorentzian Cauchy-Riemann (LCR) structure. This action describes
all current phenomenology: 1) The Poincar\'e group is determined. 2) Stable
solitonic LCR-tetrads are found, which belong to representations of the
Poincar\'e group and they are determined by the irreducible and reducible
algebraic quadratic surfaces of CP3. 3) The static (irreducible) LCR-structure
is identified with the electron and the stationary (reducible) one is
identified with the neutrino. The antiparticles have conjugate LCR-structures.
4) The LCR-tetrad defines Einstein's metric and the electromagnetic tensor for
all the solitons. 5) An effective leptonic standard model action is derived
using the Bogoliubov recursive procedure. 6) The three generations of flavors
are implied by the limited number of permitted algebraic surfaces of CP3. 7)
For every LCR-structure there exists a solitonic distributional gauge field
configuration, identified with the corresponding quark, which explains the
lepton-quark correspondence. It is explicitly computed for the static
LCR-structure and a quark confinement mechanism is proposed
