1. Laertes is about to stab Hamlet. Claudius, watching from the wings, desperately wants Laertes to stab Hamlet and has implanted a device in Laertes’ brain that, if activated, will force him to stab Hamlet. Claudius intends to activate the device if it appears that Laertes will change his mind at the last moment. Laertes, however, stabs Hamlet of his own accord and Claudius’s device is never a...

On the coupling g f 0 K + K − and the structure of f 0 ( 980 )

We use light-cone QCD sum rules to evaluate the strong coupling gf0K+K− which enters in several analyses concerning the scalar f0(980) meson. The result is 6.2 ≤ gf0K+K− ≤ 7.8 GeV. PACS. 12.38.Lg – 13.75.Lb – 14.40.Cs

0 K + K − and the structure of f 0 ( 980 )

We use light-cone QCD sum rules to evaluate the strong coupling gf0K+K− which enters in several analyses concerning the scalar f0(980) meson. The result: 6.2 ≤ gf0K+K− ≤ 7.8 GeV is larger than in previous determinations.

− F ( F · R ) / ‖ F ‖ 2 ) in Iteratively Solving the Nonlinear System of Algebraic Equations F ( x ) = 0

In this continuation of a series of our earlier papers, we define a hypersurface h(x, t) = 0 in terms of the unknown vector x, and a monotonically increasing function Q(t) of a time-like variable t, to solve a system of nonlinear algebraic equations F(x) = 0. If R is a vector related to ∂h/∂x, we consider the evolution equation ẋ = λ [αR+βP], where P = F−R(F ·R)/‖R‖2 such that P ·R = 0; or ẋ = ...
