[en] This report briefly discusses research on: new limits on light axionic fields; non-newtonian gravity; the search for the fifth force; and a test of special relativity by a determination of the Lorentz limiting velocity

[en] We consider in detail the effects of local mass anomalies in Eoetvoes-like experiments. It is shown that in the presence of an intermediate-range non-gravitational force, the dominant contributions to both the sign and magnitude of the Eoetvoes anomaly may come from nearby masses and not from the earth as a whole. This observation has important implications in the design and interpretation of future experiments, and in the formulation of unified theories incorporating new intermediate-range forces

[en] We give limits on the contribution to the cosmic dark matter density of neutral, stable, strongly interacting massive particles (SIMPs). The limits are inferred from an accelerator mass spectrometry (AMS) experiment at the Purdue Rare Isotope Measurement Laboratory (PRIME Lab). The experiment accelerated nuclei of both gold and iron. The 'SIMP signal' would be discovery of nuclei of these elements with anomalous masses. Since no such signal was observed for SIMP masses up to over 1 TeV, cosmic SIMP density limits may be given. Determining the minimum time of exposure to SIMPs trapped in the galaxy is a crucial element in the analysis of each sample

[en] The existing data on energy-dependences of the fundamental parameters of K⁰-/bar K/⁰ system, and the limits on the decay K⁺ → π⁺ + (invisible neutrals), are used in conjunction with geophysical data to explore the coupling of the putative fifth force to quantities other than baryon number. 21 refs., 2 tabs

[en] We reconsider the possible detection of hyperphotons (γ/sub Y/) in the decay mode, K/sub L/ → π⁺π/sup /minus//γ/sub Y/. We find it to have certain advantages over K⁺ → π⁺γ/sub Y/ in setting limits on new forces coupling to hypercharge. The prospects for studying this decay mode in the near future are discussed. 10 refs

[en] We review recent experimental and theoretical work dealing with the proposed fifth force. Further analysis of the original Eotvos experiments has uncovered no challenges to our original assertion that these data evidence a correlation characteristic of the presence of a new coupling to baryon number or hypercharge. Various models suggest that the proposed fifth force could be accommodated naturally into the existing theoretical framework. 40 refs

[en] Solar models which could possibly solve the solar neutrino problem without incorporating neutrino oscillations are discussed. In particular it is found that is it possible to h ave solar models with rapid differential rotation and low surface oblateness, if one allows for the presence of strong toroidal magnetic fields with the proper configuration
