Generalized Relativistic Meson Wave Function
We study the most general, relativistic, constituent meson
wave function within a new covariant framework. We find that by including a
tensor wave function component, a pure valence quark model is now capable of
reproducing not only all static pion data (, )
but also the distribution amplitude, form factor , and structure
functions. Further, our generalized spin wave function provides a much better
detailed description of meson properties than models using a simple
relativistic extension of the nonrelativistic wave function.Comment: 17 pages, REXTeX 3.0 file, (uuencoded postscript files of 8 figures

Aspects of and Production in Polarized Proton-Proton Collisions
Several topics of relevance to low transverse momentum and
production in polarized proton-proton collisions
are discussed. The leading contributions to the low
production cross-sections via , , and
initial states are calculated as well as the corresponding spin-spin
asymmetries. We find that production increases relative to direct
and production, providing up to of the observable
pairs arising from decays in collisions at . The spin-dependence of production, however, is much smaller
than for either direct or production and so will likely be far
less useful than either process in probing the polarized gluon structure
function of the proton. A subset of the radiative
corrections to production involving initial state quarks are also
performed and compared to leading order predictions.Comment: 21 pages + 5 postscript figures (included), OCIP/C-94-
Transfer matrix method and intermittency generating dynamics
A transfer matrix method relating the process of refinement of a fractal
measure to thermodynamic formalism of an appropriate Ising model is applied to
the analysis of intermittency in hadron collisions revealing that underlying
dynamics is that of period doublings.Comment: 13 pages, report IHEP 93-10
