Using an aspect of rapidity bins with finite sizes the short-range and longrange behaviors of two-particle correlation, the connection of two particle correlation function with factorial moment and factorial correlator are investigated; and experimental data for 16 O+Em interactions at 14.6, 60 and 200 A GeV and 32 S+197Au interactions at 200A GeV are analyzed. It is shown that the bin-average of two-particle correlation function can naturally give a coordinate description of dynamical fluctuation such as the second order factorial moment and 1+1 order factorial correlator .

From the shell model configurations, valence nucleon effective interactions and fermion E2 transition operator, the sdgIBM-1 Hamiltonian and boson E2 transition operator are derived micoscopically with the help of Dyson boson expansion technique. Spectra and reduced E2 matriX elements are calculated for the 192,190,188Os isotopes. Present theoritical results fit experimental data quite well.

The definitions of density function and moment of multiplicity distribution are introduced,and the method of moment analysis in e+ e- and proton-proton (pp) interactions is extended into nu-cleus-nucleus (AA) interactions. We analyze the data for relativistic nucleus-nucleus collisions and cal-culate the values of Hq for charged particle multiplicity distributions, by which we study systematically the dependences of Hq on incident energy, mass of colliding system, pseudorapidity interval, centrality and truncation of multiplicity. We compare the oscillation structures induced by e + e-, pp and AA inter-actions, and the comparison and analysis are carried out between experimental data and QCD predic-tion. The latest results are given in this paper.

The non-topological soliton bag model of Friedberg and Lee (F-L model), whichis developed by Goldflam and Wilets and others, has been much successful indescribing phenomenologically the static properties of hadrons and their behavior atlow energy. Particularly, with the finding of the numerical soliton solution for thespecial case of temperature being zero and bag constant B=0^+, the model affordsus a very intuitive physical explanation of the color confinement in QCD *** other different values of B, especially for non-trivial temperature, someinvestigation on the deconfinement transition has been made in Ref.[3], etc. byanalyzing the variation condition in which soliton solutions exist, but it remains to besettled to find the concrete solutions. In this note, we will solve directly the

A simple model is designed to simulate, by using the mean free path method, the probability of Higgs boson production at the Large Hadron Collider （LHC）. The probability that the colliding particles could get close to a given distance with different colliding energies is discussed in this model. Calculated results imply that the probability of producing a Higgs boson is near zero according to the existing theoretical mechanism for Higgs boson production.

This paper is concerned with some nonlinear heat equations with initial condition and anti-periodic boundary condition. Also some two-point value nonlinear heat equations with anti-periodic boundary condition are discussed. The existence and uniqueness of the solutions are given. Some asymptotic behaviors of the solutions are studied.

In this paper we prove that for any prime power q equivalent to 3 (mod 8) there exist 4 - {q(2); k, k, k, k; lambda} supplementary difference sets (SDSs) with k = q(q - 1)/2, lambda 4k - q(2), and Hadamard matrices of order 4q(2), and give several constructions of these SDSs. Moreover, combining the results of reference [1], we conclude that for any prime p equivalent to 3 (mod 8) and integer r greater than or equal to 1 there exists an Hadamard matrix of order 4p(2r).
