New form of vector meson dominance and the dependence on the vector meson mass squared

We propose a new form of VMD which relates the reactions πN → VN and γN → πN. Our form fits the experimental results within errors. As our restriction is strong enough, we can discuss the k_μ² dependence. Unexpectedly the k_μ² dependence is larger and this suggest the necessity of generalized vector dominance.     

Manifestation of intermediate meson loop effects in charmonium decays

We report the progress on understanding some of those existing puzzles in charmonium decays.We show that the intermediate meson loops (IML) as a long-distance transition mechanism will provide novel insights into these issues.In particular,we show that the IML mechanism would be essentially important for understanding the ψ(3770) non-DD decays.We also comment that such a mechanism is correlated with the Okubo-Zweig-Iizuka (OZI) rule evasions in charmonium hadronic decays.     

Causal action-at-a-distance interpretation of the aspect-Rapisarda experiments

Recent results in EPR-type experiments on singlet photon pairs which establish (a) the non-existence of local hidden variables, (b) the existence of quantum superluminal correlations between the action of independent parts of a measuring device separated by space-like intervals, are interpreted causally within the frame of the stochastic interpretation of quantum mechanics.     

A possible interpretation of the \pi_1(1400) exotic meson

Recent progress on the chiral unitary approach to meson meson and meson baryon interactions

We report on recent progress on the chiral unitary approach, analogous to the effective range expansion in Quantum Mechanics, which is shown to have a much larger convergence radius than ordinary chiral perturbation theory, allowing one to reproduce data for meson meson interaction up to 1.2 GeV. Applications to physical processes so far unsuited for a standard chiral perturbative approach are presented. Results for the extension of these ideas to the meson baryon sector are discussed, together with applications to kaons in a nuclear medium and K⁻ atoms.     

New physics effects from B meson decays

In this talk, we point out some of the present and future possible signatures of physics beyond the Standard Model from B-meson decays, taking R-parity conserving and violating supersymmetry as illustrative examples. An expanded version is available on hep-ph archive.     

New interpretation of the Hubble law

New interpretation of the Hubble law is considered. It is supposed that emptiness does not exist, but there is a real physical medium—Ψ-ether, which uniformly fills all the world space as was supposed by Maxwell, Lorentz, and Poincare at the end of the 19th to the beginning of the 20th centuries. The modern (not mechanical!) Ψ-ether is defined as the Bose-Einstein condensate of neutrino-antineutrino pairs of the Cooper type and it is a carrier of electromagnetic field. The two different forms are predicted for the red shift in the Hubble diagrams in the region of r ≳ 6500 Mpc. Presented on the 12th International Conference “Selected Problems of Modern Physics,” Sec. 1, Dubna, June 8–11, 2003. The text was submitted by the author in English.     

Refined interpretation of Christiansen-filter experiments and neutron scattering lengths of the lead-isotopes

A refined interpretation of Christiansen filter experiments is described, which allows for the effects of inhomogeneities in the powder column of the filter. Using this procedure the evaluation of experiments on enriched samples of lead isotopes provided the neutron coherent scattering lengths (in fm) for the separated isotopes:b (204) =10.6 ± 2.0;b (206)=9.23 ± 0.05;b (207)=9.28 ± 0.04 andb (208)=9.50 ± 0.06. The corresponding potential scattering radius R was obtained by taking account of resonance contributions as earlier used in the determination of the neutron's electric polarizability. The found R=9.74 ± 0.07 fm is in good argreement with the literature. This confirms the correctness of the used resonance contributions.Work partially supported by the Bundesministerium für Forschung und Technologie     

New neutrino experiments

Following incredible recent progress in understanding neutrino oscillations, many new ambitious experiments are being planned to study neutrino properties. The most important may be to find a non-zero value of θ₁₃. The most promising way to do this appears to be to measurev _μ →v _e oscillations with anE/L near Δm _atmo ² . Future neutrino experiments are great.
