Typical conditions found in heavy-ion collisions at GSI are explored. As in the case of zero temperature, the angular momentum components larger than L=0 contribute significantly to the finite temperature antikaon optical potential at finite momentum. It is found that the particular treatment of the medium effects has a strong influence on the behavior of the antikaon potential with temperature. Our self-consistent model, in which antikaons and pions are dressed in the medium, gives a moderately temperature dependent antikaon potential which remains attractive at GSI temperatures, contrary to what one finds if only nuclear Pauli blocking effects are included.10 p.application/pdfeng(c) The American Physical Society, 2002AntikaonsReaccions nuclearsConstitució de la matèriaAntikaonsNuclear reactionsConstitution of matterinfo:eu-repo/semantics/article505049info:eu-repo/semantics/openAccess
