Magnetic shielding for large photoelectron multipliers for the OSIRIS facility of the JUNO detector

Autor: Smirnov, O., Korablev, D., Sotnikov, A., Stahl, A., Steinmann, J., Khudyakov, V., Avetissov, I., Zykova, M.

We present the technical design and characteristics of the magnetic shield developed for 20" PMTs of the low-background OSIRIS facility. A ribbon of amorphous alloy with the extreme magnetic permeability was used in its design providing the excellent

We present numerical simulations and experimental results of the self-modulation of a long proton bunch in a plasma with linear density gradients along the beam path. Simulation results agree with the experimental results reported in arXiv:2007.14894

Chromomagnetic Catalysis of Chiral Symmetry Breaking and Color Superconductivity

Autor: Ebert, D., Khudyakov, V. V., Klimenko, K. G., Toki, H., Zhukovsky, V. Ch.

It is shown in the framework of an extended NJL model with two flavors that some types of external chromomagnetic field induce the dynamical chiral or color symmetry breaking even at weakest attraction between quarks. It is argued also that an extern

In the framework of a (2+1)-dimensional P-even massive Gross-Neveu model, an external magnetic field is shown to induce a parity breaking first order phase transition. Possibility of applying the results obtained to description of magnetic phase tran
