The Magnetic Field

The classical processes: the conversion of photons into gravitons in the static electromagnetic fields are considered by using Feynman perturbation techniques. The differential cross-sections are presented for the conversion in the electric field of the flat condenser and the magnetic field of the solenoid. A numerical evaluation shows that the cross-sections may have the observable value in the present technical scenario.

An attempt is made to present some experimental predictions of the five dimensions Kaluza–Klein theory. The conversion of photons into dilatons in the static magnetic fields are considered in detail. The differential cross-sections are presented for the conversions in a magnetic field of the flat condensor and a magnetic field of the solenoid. A numerical evaluation shows that in the present technical scenario, the creation of dilatons at high energies may have the observable value.

The 16O(g,n)3He3a-reaction was investigated with the aid of the diffusion camera placed in the magnetic field and irradiated with a beam of bremsstrahlung g-quanta with an endpoint energy of 150 MeV. In to the curve of excitation of the system of 2a‑particles the resonance, identified as the ground state of the nucleus 8Be, were observed. The partial channels of production of these state (16O(g,n)3Hea8Ве0) were isolated and kinematical parameters of g-quantum and neutron were calculated. The absolute total cross-section of the partial channels in the energy interval from the threshold up to 120 MeV was measured. It has been established that the reaction is of a successive type: at first, the neutron is knocked out, and the residual nucleus 15О is in the excited state. The differential cross sections 16O(g,n)3Hea8Ве0-reaction has been measured and the dependence of the asymmetry coefficient distributions of the g-quantum energy and the excitation energy of the compound nucleus at the first intermediate stage of decomposition. The results are explained by the quantum interaction with a quasideuterons model.

Highly Evolved

Some species of fish show highly evolved mechanisms by which they can detect exogenous electric and magnetic fields. The detection of electromagnetic fields has been hypothesized to exist in humans, despite the lack of specialized sensors. In this experiment, planaria were tested in a t-maze with weak electric current pulsed in one arm to determine if the planaria showed any indication of being able to detect it. It was found that a small proportion of the population seemed to be attracted to this current. Additionally, if the experiment was preceded by a geomagnetic storm, the planaria showed a linear correlation increase in the variability of their movement in response to the presence of the weak electric field. Both of these results indicate that a subpopulation of planaria show some ability to respond to electromagnetic fields.

We study the production of Higgs and Z bosons which has been proposed as an option of \(e^{+}e^{-}\) collision at the ILC, CLIC with the polarization of the electron and positron beams in Randall-Sundrum model (RSM). The differential cross-sections are presented and numerical evaluation is given. Based on the results, we show that the advantageous direction to collect Higgs is perpendicular to the direction of the initial \(e^{-}\) beam. With the high integrated luminosity and at the high degree of polarization, the reaction can give observable cross-sections in future accelerators (ILC, CLIC).

Kaluza Klein

An attempt is made to present experimental predictions of the Kaluza-Klein based models. We consider the creation of gravitons and dilatons by photons in an external electromagnetic field, namely in the electric field of a flat condenser and in the static magnetic field. The relation between the cross-sections of these two processes is given. A numerical evaluation shows that in the present technical scenario the creation of high frequency gravitons and dilatons may be indirectly observable.

A review of Randall-Sundrum model with stressing on radion phenomenology is presented. The radion production in the external electromagnetic field is considered. The total cross sections for the conversions in the presence of the electric field of the flat condenser as well as in the magnetic field of the solenoid are calculated in details. Based on our results a laboratory experiment for production and detection of the light radions may be described.
