Data on the fluctuation in depth of maximum development of cosmicray air showers with laboratory energies in the range (105/107) TeV are found to be inconsistent with a In2s energy dependence of σpp, when that quantity is derived from σpa with a geometrical scaling model by means of Glauber theory. The data agree remarkably well with the Block-Cahn best-fit extrapolation of ISR results.
We present the first nontrivial anisotropic cosmological solution ofd = 11 supergravity. The solution given is of typeM 1 × M7, where the metric onM 4 is of Bianchi type-VI0 andM 7 is taken to bo the locally flat torus. The behaviour of the solution near the initial singularity and at later stages of the expansion is discussed.
Based on the argument that interchangeable random variables are the appropriate tool for the description of indistinguishable particles it is shown that Bose-Einstein statistics can be derived from the statistics of classical (i.e. independent) particles by means of a multivariate version of de Finetti’s theorem.
Events with large missing transverse momentum observed by the CERN SPS pp colliders are investigated with recourse to the model which was proposed to explain the phenomena in the cosmic-ray air showers above 1015 eV. It is shown that new heavy particles introduced in the model give an explanation for these events.
Instanton contributions to the two-dimensionalO 3 Heisenberg model are studied with use of the procedures developed by Callan, Dashen, and Gross. A sharp transition from weak- to strong-coupling behaviour found in Monte Carlo simulations by Shenker and Tobochnik is shown to be explained by the inclusion of instanton effects.
We discuss tlie reason why there is a discrepancy between the calculated and the experimental cross-section in heavy-ion-heavy-ion scattering problem such as in the fusion reaction of64Ni+64Ni. We show that the difference in the part of the binding energies together with a factor due to the different extent of contact can explain this.
Perturbation of the atomic energy levels by an intense electromagnetic field is theoretically investigated. A dressing interaction Hamiltonian is constructed in the second-quantization formalism and the correct transitional Hamiltonian formulated.
A dynamical scheme of quark and letpon family unification is investigated. This scheme is based on a unique nonassociative algebra. This algebraic unification results in three families withC-P- andT-conserving generation-changing interaction and a fourth family withP- andT-violating interaction.
The recent discovery of quantized red-shifts for galaxies suggests a cosmic form of quantum mechanics which may explain the observed properties of galaxies. Some consequences of the new theory were presented in two papers. This paper adds to the list by exploring possible connections between the cosmic Planck’s constant, (hg), and other fundamental constants of nature.
We present the analytic value of the QED 8th-order contributions to the electron anomaly coming from three second-order self-mass or vertex insertions into the lowest-order graph.
The Dirac-like equation recently reformulated in phase space is shown to yield a mass formula in satisfactory quantitative agreement with experimental data for families of baryons. The proposed theoretical scheme gives also the possibility of calculating the radii of spin-1/2 baryons, which are found to be of the order of 1 fm.
It is suggested that a double galaxy may be the cosmic analog of a hydrogen atom, in the sense that quantum mechanics applies to both. An empirica approach is suggested to explore a possible Bohr model for double galaxies and some preliminary calculations are presented. The calculations provide cautious support for gravitational Bohr orbits in double galaxies.
A model is presented in which gravity and electroweak interactions are described in a unique framework. As a consequence we are led to predict very massive particles (of masses ≌ 369 and 520.3 GeV) which intermediate Wμ-Wμ and Wμ-Zμ interactions. This new interaction is the short-range counterpart of gravitational interaction.
We calculate the contribution of the gamma-rays from the galactic plane to the cosmic-ray counting rate. By extrapolating the gamma-ray flux measured by satellites, we obtain a good fit of the cosmic-ray anisotropy detected at primary energiesE0= (1013/1014) eV.
A minimum condition on a suitable function, built with the atom energy level values from Dirac’s formula, produces coincidences involving the numbers, given by Pauli’s principle, that describe the electron arrangement inside the atom shells.
We show that the damped wave equation for the propagation of the electromagnetic waves in a resistive medium, possess the algebraic structure of the Lie-isotopic type.
The received periodTr is the difference between the arrival times of two successive signal peaks. If the Universe were static the two successive propagation times hence the received periodTr and the emitted periodTe would be equal. Some opposite proposals are criticized. The local co-ordinates of general relativity (for which the dipole term of the cosmic background radiation is zero can be interpreted as a local ether. Indeed the correct average values for the recession velocities of the galaxies are given by the classical and not by the relativistic Doppler-Fizeau formulae.
Using the relativistic BS wave function of the (0-1/2) electromagnetic bound system, the differential cross-section for the scattering of a lepton by a (0-1/2) bound system is calculated. The analytical expressions of the electromagnetic form factors of the bound system are also obtained.
