Query: Rest masses of elementary particles as effective masses at zero
  temperature   We introduce a new approach to generate dinamically the masses of elementary
particles in the $SU(3)_C \times SU(2)_L \times U(1)_Y$ Standard Model without
Higgs Sector (SMWHS). We start from the assumption that rest masses correspond
to the effective masses of particles in an elementary quantum fluid at zero
temperature. These effective masses are obtained through radiative corrections,
at one-loop order, in the context of the real time formalism of quantum field
theory at finite temperature and density. The quantum fluid is described in
structure and dynamics by the SMWHS and it is characterized by non-vanishing
chemical potentials associated to the different fermion flavour species.
Starting from the experimental mass values for quarks and leptons, taking the
top quark mass as $m_t = 172.916$ GeV, we can compute, as an evidence of the
consistency of our approach, the experimental central mass values for the
$W^{\pm}$ and $Z^0$ gauge bosons. Subsequently we introduce in the SMWHS a
massless scalar field leading to Yukawa coupling terms in the Lagrangian
density. For this case we can also compute the experimental mass central values
of the $W^{\pm}$ and $Z^0$ gauge bosons using a top quark mass value in the
range 169.2 GeV $< m_{t} < 178.6$ GeV; this range for the top quark mass
implies that the scalar boson mass must be in the range $0 < M_{H} < 152$ GeV.
