Plane SPDC-Quantum Mirror

In this paper the kinematical correlations from the phase conjugated optics (equivalently with crossing symmetric spontaneous parametric down conversion (SPDC) phenomena) in the nonlinear crystals are used for the description of a new kind of optical device called SPDC-quantum mirrors. Then, some important laws of the plane SPDC-quantum mirrors combined with usual mirrors or lens are proved only by using geometric optics concepts. In particular, these results allow us to obtain a new interpretation of the recent experiments on the two-photon geometric optics.Comment: 12 pages, 5 figures. arXiv admin note: substantial text overlap with arXiv:0810.340

A New Optimal Bound on Logarithmic Slope of Elastic Hadron-Hadron Scattering

In this paper we prove a new optimal bound on the logarithmic slope of the elastic slope when: elastic cross section and differential cross sections in forward and backward directions are known from experimental data. The results on the experimental tests of this new optimal bound are presented in Sect. 3 for the principal meson-nucleon elastic scatterings: pion-nucleon, kaon-nucleon at all available energies. Then we have shown that the saturation of this optimal bound is observed with high accuracy practically at all available energies in meson-nucleon scattering.Comment: format revtex4, 4 pages, 1 figur

Analytical Description of Hadron-Hadron Scattering via Principle of Minimum Distance in Space of States

In this paper an analytical description of the hadron-hadron scattering is presented by using PMD-SQS-optimum principle in which the differential cross sections in the forward and backward c.m. angles are considered fixed from the experimental data. Experimental tests of the PMD-SQS-optimal predictions, obained by using the available phase shifts, as well as from direct experimental data, are presented. It is shown that the actual experimental data for the differential cross sections of all principal hadron-hadron [nucleon-nucleon, antiproton-proton, mezon-nucleon] scatterings at all energies higher than 2 GeV, can be well systematized by PMD-SQS predictions.Comment: 18 pages, 10 figure

Toward a New Phenomenon: Super-Cerenkov Radiation

In this letter a new coherent gamma emission mechanism, called Super-Cerenkov radiation, is introduced. The SCR is expected to take place when the charged particle is moving in a medium with a phase velocity satisfying the super-coherent condition. The results on an experimental test of SCR in RICH detector are presented.Comment: 5 pages, 2 figure

Super-Cerenkov Radiation: A new phenomenon useful for RICH Detectors

In this contribution the Super-Cerenkov radiation (SCR) as a new phenomenon which includes in a more general and exact form the usual Cerenkov effect is presented. The Super-Cerenkov effect at Cerenkov threshold in the radiators of RICH detectors is investigated. The results on the experimental test of the super- Cerenkov coherence conditions are presented. The SCR-predictions are verified experimentally with high accuracy chi/n_{dof}=1.47 by the data on the Cerenkov ring radii of electron, muon, pion and kaon, all measured with RICH detector. Moreover, it is shown that the Super-Cerenkov phenomenon can explain not only subthreshold CR but also the observed secondary rings (or anomalous Cerenkov radiation) observed at CERN SPS accelerator. The influence of medium on the particle propagation properties is also estimated and the refractive properties of electrons, muons, pions, in the radiator C4F10Ar are obtained. So, we proved that the refractive indices of the charged elementary particles in medium are also very important for the RICH detectors, especially at low and intermediate energies.Comment: 9 pages, 7 figure
