Scalar unparticle production in the process is studied from unparticle physics perspective. We have calculated and evaluated the cross sections for muon and Z boson exchange when the  beams are initially polarized. Numerical calculations show that the cross section of collisions depends strongly on the polarized condition of the initial beams and the collision energy . The results are plotted in the energy reach available at the present accelerators and the future high energy frontier muon colliders as shown in the scheme by Muon Accelerator Program (MAP) and other different colliders.

Energy Surfaces

Ab initio calculations of energy surfaces of the system [Formula: see text] corresponding to dissociation into H(2s) + H2 (X, 1Σg+) and H(2p0) + H2(X) are presented. For a thermal collision energy (0,064 eV), multistate close-coupling calculations are performed. In relation to experiments in progress, elastic and inelastic differential rotation cross sections are shown. For the quenching of H(2s) by H2:[Formula: see text]the cross section is obtained from an interference phenomenon between the elastic amplitudes associated to the two molecular states related to the entrance and exit channels, respectively. After criticizing the models used for the collision, which are valid only for small scattering angles, improvements are proposed in conclusion.[Journal translation]

Charge exchange cross sections for the four systems He+, Ne+ + Ar, Kr have been measured, ap­plying slow ions gathering techniques. The values are several 1O-16 cm2 and are almost constant between 20 and 200 eV collision energy. The comparison with previously published data for charge exchange into optically excited higher states of the ions show that these reactions prefer at least at 25 to 30% endothermic channels instead of the exothermic one without excitation. - Additionally the cross section of the endothermic process Ar++Ne was measured. Above a threshold energy of 17 eV it shows a strong increase and a constant value of 7 · 10-17 cm2 between 20 and 200 eV.

The work of multilayer glass structures for central and eccentric compression and bending are considered. The substantiation of the chosen research topic is made. The description and features of laminated glass for the structures investigated, their characteristics are presented. The analysis of the results obtained when testing for compression, compression with bending, simple bending of models of columns, beams, samples of laminated glass was made. Overview of the types and nature of destruction of the models are presented, diagrams of material operation are constructed, average values of the resistance of the cross-sections of samples are obtained, the table of destructive loads is generated. The need for development of a set of rules and guidelines for the design of glass structures, including laminated glass, for bearing elements, as well as standards for testing, rules for assessing the strength, stiffness, crack resistance and methods for determining the strength of control samples is emphasized. It is established that the strength properties of glass depend on the type of applied load and vary widely, and significantly lower than the corresponding normative values of the strength of heat-strengthened glass. The effect of the connecting polymeric material and manufacturing technology of laminated glass on the strength of the structure is also shown. The experimental values of the elastic modulus are different in different directions of the cross section and in the direction perpendicular to the glass layers are two times less than along the glass layers.
