β¦ Synopsis
We have previously interpreted the various large apparent violations of the naΓ―ve Okubo-Zweig-Iizuka (OZI) rule found in many channels in pp annihilation at LEAR as evidence for an intrinsic polarized ss component of the nucleon wave function. The model is further supported by new data from LEAR and elsewhere. Here we discuss in more detail the possible form of the ss component of the nucleon wave function, interpret the new data and clarify the relative roles of strangeness shakeout and rearrangement, discuss whether alternative interpretations are still allowed by the new data, and propose more tests of the model.

Results for the disconnected contributions to matrix elements of the vector current and scalar density have been obtained for the nucleon from the Wilson action at p = 6 using a stochastic estimator technique and 2000 quenched configurations. Various methods for analysis are employed and chiral extr
By imposing the constraints of charge symmetry we show that the strangeness magnetic moment of the nucleon can be expressed in terms of empirical magnetic moments and ratios of valence quark magnetic moments. The latter are determined using modern chiral extrapolation techniques and recent low mass
