Saturation Of Optimal Entropic Resonance Limits In Pion-Nucleus Scattering In $Δ(1236)$-Elementary Resonance Region

In this paper, it is shown that the experimental values of the nonextensive scattering entropies $S_L (p)$ and $S_θ(q)$ for the pion-nucleus ($π^0 He, π^0 C, π^0 O, π^0 Ca$) scatterings, in the energy region corresponding to $Δ(1236)$ resonance in the elementary pion-nucleon interaction, are well described by the entropic optimal resonance predictions $S_L^o1 (p)$ and $S_θ^o1 (q)$ and when the nonextensivities indices are correlated by a Riesz-Thorin-like relation: 1/2p+1/2q=1.

Pionic Supergiant Radiohalos as Integral Record of Pion Emission During Nuclear Fission

In this paper we presented a short review of radioactive halos as from the perspective of their interpretation as integral record in time of different kind of known or unknown radioactivities. A special attention is paid for the unified interpretation of the supergiant halos (SGH), discovered by Grady, Walker and Laemlein, as integral record of pion emission during fission.

Quantum Mirrors and Crossing Symmetry as Heart of Ghost Imaging

In this paper it is proved that the key to understanding the ghost imaging mystery are the crossing symmetric photon reactions in the nonlinear media. Hence, the laws of the plane quantum mirror (QM) and that of spherical quantum mirror, observed in the ghost imaging experiments, are obtained as natural consequences of the energy-momentum conservation laws. So, it is shown that the ghost imaging laws depend only on the energy-momentum conservation and not on the photons entanglement. The extension of these results to the ghost imaging with other kind of light is discussed. Some fundamental experiments for a decisive tests of the [SPDC-DFG]-quantum mirror are suggested.

Quantum Crossing Symmetry as Heart of Ghost Imaging

In this paper it is shown that the key to understanding the ghost imaging mystery are the crossing symmetric photon reactions in the nonlinear media. Then, an intuitive mechanism for the description of the ghost imaging in terms of the quantum mirror (QM) is presented. Moreover, we prove that the ghost imaging laws depend only on the energy-momentum conservation and not on the photons entanglement.

A New Interpretation of Two-Photon Entangled Experiments via Quantum Mirrors

In this paper the coherence and crossing symmetry of the electromagnetic interaction of photons involved in the spontaneous parametric down conversion (SPDC) phenomena in nonlinear crystals, are investigated.

Quantum Mirrors Via SPDC-Crossing Symmetric Phenomena and a New Geometric Optics

In this paper, the crossing symmetry of the photons, from spontaneous parametric down conversion (SPDC) phenomena in nonlinear crystals, is used for the development of a new geometric optics based on quantum kinematic correlations. On this basis, a new interpretation of the recent results on the two photon entangled experiment is obtained. A new field of applications is suggested.

From Cherenkov Radiation to Generalized Super-Cherenkov Exotic Decays

Generalized Super-Cherenkov Radiations (SCR), as well as their SCR-signatures are investigated. Two general SCR-coherence conditions are found as two natural extremes of the same spontaneous particles decays in (dielectric, nuclear or hadronic) media. The main results on the experimental test of the super-coherence conditions, obtained by using the experimental data from BNL, are presented. The interpretation of the observed anomalous Cherenkov rings as experimental evidence for the HE-component of the SCR is discussed.

The induced nuclear and subnuclear decays are discussed. Moreover, using the recent results on the spontaneous fission half lives T of the heavy nuclei with Z new predictions on the pionic yields in the region of superheavy elements are presented.

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.

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.

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.

Nonextensive quantum statistics and saturation of the PMD-SQS optimality limit in hadron-hadron scattering

In this paper, new results on the analysis in hadron-hadron scattering are obtained by using the nonextensive quantum entropy and principle of minimum distance in the space of quantum states (PMD-SQS). Using Tsallis-like scattering entropies, the optimality as well as the nonextensive statistical behavior of the quantum scattering systems are investigated in an unified manner. A connection between optimal states obtained from the principle of minimum distance in the space of quantum states and the most stringent (MaxEnt) entropic bounds on Tsallis-like entropies for quantum scattering, is established. The generalized entropic uncertainty relations as well as the correlation between the nonextensivities p and q of the scattering statistics are proved. New results on the experimental tests of the saturation of the optimality limit}, as well as on the test of optimal entropic bands obtained by using the experimental pion-nucleon, kaon-nucleon, antikaon-nucleon phase shifts, are presented. The nonextensivity indices p and q are determined from the experimental entropies by a fit with the optimal entropies obtained from the principle of minimum distance in the space of states. Strong experimental evidences for the p-nonextensivity index in the range p=0.6 with q=p/(2p-1)=3, is obtained from the experimental data.

Saturation of optimality limits in hadron-hadron scatterings

In this paper the optimal unitarity lower bound on logarithmic slope of the diffraction peak is investigated. It is shown that the unitarity lower bound is just the optimal logarithmic slopes predicted by the principle of least distance in space of states. A systematic tendency towards the saturation of the most forward-peaked limit is observed from all the available experimental data of all principal hadron-hadron (e.g., antiproton-proton, proton-proton, kaon-proton, pion-proton) scatterings practically at all laboratory momenta.
