The effect of γ-radiation dose on the surface energy characteristics of commercial polytetrafluoroethylene (PTFE) of five different grades has been studied. In the course of PTFE irradiation in air, radiation oxidation leads to the appearance of fun

During γ-irradiation of polyethylene, its gradual amorphization accompanied by a decrease in the melting point and the heat of melting occurs. Almost complete amorphization of the polymer with crosslinking occurs at a dose of 1400 Mrad according to

We develop a numerical method to compute the probabilities of multiparticle production in weakly coupled scalar theories. Our technique is based on D.T. Son's semiclassical method of singular solutions. Applying it to the process $1 \to n$ in the unb

The surface of polytetrafluoroethylene (PTFE) irradiated with an IR laser was investigated by Raman spectroscopy. The degree of change in the surface depends on the fluence of the radiation and on the impact zones around the center spot of the laser

New physics in neutrino sector can reveal itself via non-standard neutrino interactions which can result in modification of the standard picture of neutrino propagation in matter. Experiments with atmospheric neutrinos has been used to probe this sce

Energy characteristics of the irradiated surface of a polytetrafluoroethylene film depend on the energy and fluence of bombarding MeV protons. Irradiation with 2–4 MeV protons leads to an increase in the surface free energy; 4 MeV protons at a flue

The visible and dark sectors of particle physics can be connected via kinetic mixing between ordinary and hidden photons. If the latter is light its production in high energy collisions of ordinary particles proceeds via oscillations with ordinary ph
