It is proposed that some low-energy properties of the interaction of one or more fermions with a monopole are sensitive to, and hence can be used as probes for, extremely small distances. One possible example of such properties is studied in detail. (ERA citation 08:057878)

This project involves five inter-related subprojects: (1) derivation of the intermediate range nucleon-nucleon interaction using a new method that utilizes much shorter and simpler analytic continuation through the unphysical region that lies between the pi N and pi pi physical regions of the N anti N implies pi pi amplitude (with significantly improved accuracy for the nucleon-nucleon interaction); (2) construction of a short range phenomenological potential that, with the theoretical part mentioned above, gives a precise fit to the nucleon-nucleon data and is parameterized for easy use in nucleon calculations; (3) phase shift analyses of the world data below 400 MeV, especially the large amount of very precise data below 20 MeV and the new data near 55 MeV that have never been analyzed properly; (4) the introduction of a K-matrix formulation of the Optimal Polynomial Expansion in order to accelerate convergence of the partial wave series at LAMPF energies; and (5) setting up of a cooperatively evaluated permanent nucleon-nucleon data bank in the 0-1200 MeV range that can be used by all nucleon-nucleon reseachers.

There are two testing grounds for strong-interaction theory (call this QCD) which are not usually included in discussions about either present or future QCD tests: inclusive polarization and exclusive reactions. (ERA citation 08:003211)

The phenomenological approach for the analysis of the scale-invariant properties of hadron/nuclear interactions at high energies is considered. The experimental data on inclusive charge particle distributions in pp/p anti p collisions are analyzed. The new scaling variable z is proposed and the scaling law for description of these processes is found. The scaling function H(z) reflecting local properties of hadronization process was constructed. 12 refs., 4 figs. (Atomindex citation 26:061205)

The phase shift data from 1 to 500 MeV are studied using a new effective range formula. An excellent fit to data up to 200 MeV is obtained which extrapolates to 500 MeV still reproducing the data with deviations small compared to the size of the error bars. This fit yields a value of the scattering length in agreement with the literature but a value of the effective range that is off. (Atomindex citation 13:712815)
