The Verifying of the Lepton s and Quark s Mass;

Delayed Splendor-The discovery of т-lepton;

By the theory of quantum field, the W-S model, the SU(5) model and the chaotic theory analyses the experience mass formula of three types of leptons and quarks, and reveals the essential relation of we、mμ、mτ、and Mq .

Starting from the QCD potential which emerges from the effective dilaton gluon coupling,the energy levels and the widths of the leptonic decay and radiative transition are calculated for heavy mesons(c and b)and compared with that of the Cornell potenial.

The relation between the leptonic decay width of J / ψand the color screening mass at finite temperature is studied by using different quark binding potentials.

The spectra,leptonic decay widths and the E1 transitions of system are calculated,with the confining potential including the color screening effect as a color confinement between quark and antiquark.

Using relativitic hydrodynamics model with the effect ofquark flavor kinetics, invariable mass dilepton spectrum of M≤4GeV/c2 has beencalculated.

With the increase of the initial baryon density, the dilepton production in invariant masses between 2mπ and 1GeV is shown to be suppressed and an abnormal peak of the dilepton spectrum appears near the invariant mass0.
