Kaons Structure in Dense Nuclear Medium
摘要
In the present work, we investigated the impact of the finite density of the nuclear medium on the properties of kaons and antikaons. We employed the combined approach of chiral SU(3) quark mean field (CQMF) model and light-cone quark model (LCQM). In the LCQM, weak decay constant and the distribution amplitudes (DAs) of valence quarks are expressed in terms of constituent quark masses. We evaluated the in-medium masses of constituent quarks in the dense nuclear matter using the CQMF model and used those as input in LCQM to investigate the medium-modified properties of \(K = (K^+, K^0)\) and \(\bar{K}\) = ( \(K^-, \bar{K}^0\) ) mesons. The impact of finite isospin asymmetry and temperature is also explored.
