The widths of a glueball decay to two pions or kaons are analyzed in the pQCD framework. Our results show that the glueball ground state has small branching ratio for two-meson decay mode, which is around 10−2. The predicted values are consistent with the data of ξ → ππ,KK if ξ particle is a 2++ glueball. Applicability of pQCD to the glueball decay and comparison with χcJ decay are also discuss...

We present an approach to generalized fermionic statistics which relates the existence of a generalized statistical behaviour to non-invariant ground states. Considering the thermal average of an operator generalization of the Heisenberg algebra, we get an occupation number which depends on the degree of mixing between symmetric and antisymmetric sectors of the ground state. A natural prescript...

The WKB and instanton answers for the tunnel splitting of the ground state in a symmetric double well potential are both reduced to an expression involving only the functionals of the potential, without the need for solving any auxilliary problems. This formula is applied to simple model problems. The prefactor for the splitting in the text book by Landau and Lifshitz is amended so as to apply ...

to evaluate the earth seismic response due to earthquake effects, ground response analyses are used to predict ground surface motions for development of design response spectra, to compute dynamic stresses and strains for evaluation of liquefaction hazards, and to determine the earthquake induced forces that can lead to instability of earth and earth-retaining structures. most of the analytical...

In this paper, we consider the existence and concentration behavior of positive ground state solution to the following problem { −hΔpu+V (x)|u|p−2u = K(x)|u|q−2u+ |u|p−2u, x ∈ RN , u ∈W 1,p(RN ), u > 0, x ∈ RN , where h is a small positive parameter, 1 < p < N , max{p, p∗ − p p−1} < q < p∗ , p∗ = Np N−p is the critical Sobolev exponent, V (x) and K(x) are positive smooth functions. Under some n...
