Future opportunities for hadron spectroscopy at the MPS

Before I go into detailed MPS experiments, I will give a summary of the status of lattice gauge calculations of glueball masses plus glueball and hybrid masses from the bag model, and the flux tube model. For the following discussion, I am going to assume that multi-quark states or molecules are best described in terms of the MIT bag model of Jaffe with its spectrum best defined by work done by R.L. Jaffe and F.E. Low using a method called The P-Matrix. Using this method one sees that all 4-quark states will appear as very broad continuum like effects that one would not associate with meson resonances, except for the S* and the delta which forms a very special threshold K/bar K/ bound systems. There is a possibility that the E(1420) may also be related to the J/sup PC/ = 1/sup + +/, qq/bar q//bar q/ spectrum having its width narrowed by a final state interaction.

Experiment designs offered for discussion preliminary to an LLNL field scale validation experiment in the Yucca Mountain Exploratory Shaft Facility

It has been proposed (``Progress Report on Experiment Rationale for Validation of LLNL Models of Ground Water Behavior Near Nuclear Waste Canisters,`` Keller and Lowry, Dec. 7, 1988) that a heat generating spent fuel canister emplaced in unsaturated tuff, in a ventilated hole, will cause a net flux of water into the borehole during the heating cycle of the spent fuel. Accompanying this mass flux will be the formation of mineral deposits near the borehole wall as the water evaporates and leaves behind its dissolved solids. The net effect of this process upon the containment of radioactive wastes is a function of (1) where and how much solid material is deposited in the tuff matrix and cracks, and (2) the resultant effect on the medium flow characteristics. Experimental concepts described in this report are designed to quantify the magnitude and relative location of solid mineral deposit formation due to a heated and vented borehole environment. The most simple tests address matrix effects only; after the process is understood in the homogeneous matrix, fracture effects would be investigated. Three experiment concepts have been proposed. Each has unique advantages and allows investigation of specific aspects of the precipitate formation process. All could …
