Restriction of Cosmological Observables VS the Breaking Parameters of Littlest Higgs Model with T-parity

In the framework of the littlest Higgs(LH) model and the littlest Higgs model with T-parity(LHT), we investigate the single top production process e~-γ→v_eb(?),and calculate the corrections of these two models to the cross section of this process.

Discovery of non-conservation of parity is an important event in the development history of physics.

20 century began from the research of symmetry,the discovery of nonconservation of parity starts epoch of research of breaking symmetry.

In this paper, we discussed the transition selection rule of electrical dipole radiation in atom physics by the parity theory and angular momentum theory in quantum.

The author analyses the differences and relationships between Dirac s equation and 2-Component neutrino theory, then shows that experment of polarzed C_o￣(60) has not overthrown the law of parity conservation.

It is shown that parity conservation is verified for the Hamiltonian system operatorwith inversion space invariance for the case u(-x)=-u(x).

The physical quantities such as energy difference δ E_I of the positive and negative parity states of the same spin, moment of inertia J￣(1) and J￣(2), electric dipole transition branching ratios of first negative parity states and the relations between them and angular momentum or rotational frequency ω and mass number A are obtained from the experimental data.
