Abstract:
The method of identification of primary cosmic ray particles of gamma families with visible energies above 800TeV has been investigated by using the results of Monte Carlo simulation.It has been found that,for proton primaries.the lateral distributio...

Abstract:
We state a fitting method of the Z0 line shape.We discuss the radiative corrections for calculating the theoretical cross sections of e+e－→ff on Z0 resonance,and compare the results from different programs.The systematic measurement errors are taken ...

Abstract:
In this paper it is shown that the topologically additional action appearing in the Heisenberg spin model can be understood as a superposition of Berry's phases for the single spins in an average fields of many particles.In the case of low temperatur...

Abstract:
In this paper one problem in H.Georgi's "MOOSE" model is discussed,and the necessity of 't Hooft anomaly matching condition for the confining phase theoretical analysis in Ri/j≈0 region is proven.

The functional formalism for the effective potential is briefly reviewed for the case of a scalar field theory by using the method of steepest descents.This formalism is then applied to quantum electrodynamics and an integral expression is derived fo...

The helicity formalism of the angular distribution for the cascade decay process e++e－→J/ψ→V+X,X→P1+Y,Y→P2+P3 (V represents a vector meson and Pi(i=1,2,3) are the pseudoscalar mesons) is presented in this paper.It provides the theoretical formulas fo...

Abstract:
The α-particle model for 16O is tested by means of the proton scattering.The elastic angular distributions for the proton-16O scattering ranging over the whole intermediate energy region are calculated without any adjustable parameter.A overall agree...

Abstract:
The two different normalization schemes of factorial moments are alalyzed carefully.It is found that in both the cases of fixed multiplicity and of intermittency independent of multiplicity,the intermittency indexes obtained from these two normalizat...

Abstract:
The coincidence between projectile-like fragments and α-particles emitted from 20Ne(14.7,19.2MeV/u)+58Ni reactions has been studied.The coincident events were caused by the sequential decay of the excited primary fragments and by the "uncorrelated" c...

Using the group theoretical method,the wavefunctions of intrinsic states for the strong coupling SU(3) limit in IBM4 are given.Then,the wavefunctions of ground states band are obtaind from the above wavefunctions by a projection method.
