The Impact

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.

Nuclear Clusters

Anisotropic flows of light nuclear clusters and hard photons are studied by nucleonic transport models in intermediate energy heavy ion collisions. The transverse momentum and rapidity dependences of the directed flow (v1) and elliptic flow (v2) are studied for light nuclear clusters and their scaling behaviors are found. The ratio of [Formula: see text] of nuclear clusters show a constant value of 1/2. Proton-neutron bremsstrahlung hard photon shows non-zero flows with the contrary sign of proton's flows.

Ion Collisions

Hard photon emitted from energetic heavy ion collisions is of very interesting since it does not experience the late-stage nuclear interaction, therefore it is useful to explore the early-stage information of matter phase. In this work, we investigated the directed flow and elliptic flow for proton-neutron bremsstrahlung hard photons in intermediate energy heavy-ion collisions. The positive directed flow and negative elliptic flow of directed photons are illustrated and they seem to be anti-correlated to the free proton's flow. Also we calculated the two-photon correlation functions from which the information of photon source was extracted, and while two-photon azimuthal correlations are presented as a good method to extract the elliptic flow parameter v2 of direct hard photons.
