Kolomeitsev, Evgeni E., 1970- The impact of kaon polarization in nuclear matter on the K- production in heavy-ion collisions / Evgeni E. Kolomeitsev, D. N. Voskresensky, B. Kämpfer. -- The impact of the kaon polarization in nuclear matter on the K- yield in intermediate-energy heavy-ion collisions is investigated. Our scenario of the strange particle production and dynamics is based on an expanding fireball model. This allows for a proper account of in-medium effects. A relation between observed K+ and K- yields is derived. Differential K- cross-sections are calculated and compared with available experimental data taken at various collision energies. It turns out that in-medium effects can modify the K- yields by factors 2 to 5 at beam energies between 2 and 1 AGeV.
