We present results for the ground state and first excited state static potentials in the confinement " phase " of the SU(2) Higgs model. String breaking and the crossing of the energy levels are clearly visible. We address the question of the cutoff effects in our results and observe a remarkable scaling of the static potentials.

The quantum state distributions of the C, radical from the UV multiphoton dissociation of allene and propyne in a pulsed molecular beam have been measured. The observed distributions for both molecules are identical and are much colder than a phase space model would predict, implying that direct dissociation is occurring in one step and isomerization in another. It is concluded that both allene...

Angular distrihutions of the ‘rC(d, 6Li)8Be reaction at i& = 78.0 MeVand the 1’B(3He, ‘Li)*Be reaction at E,,, = 71.8 MeV were measured. Transitions leading to ‘Be in the ground state and the 3.04, 16.63, 16.92, 17.64 and 18.15 MeV excited states were observed. A DWBA analysis was performed regarding the (d, 6Li) and (3He, 6Li) reactions as direct LY particle or triton transfers, respectively. ...

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 ...

The D dimensional quasi exact solutions for the singular even power anharmonic potential V (q) = aq2 + bq−4 + cq−6 are reported. We show that whilst Dong and Ma’s [5] quasi exact ground state solution (in D=2) is beyond doubt, their solution for the first excited state is exotic. Quasi exact solutions for the ground and first excited states are also given for the above potential confined to an ...
