Abstract:
We present the first observation of K- and phi absorption within nuclear matter by means of pi(-)-induced reactions on C and W targets at an incident beam momentum of 1.7 GeV/c studied with HADES at SIS18/GSI. The double ratio (K-/K+)(W)/(K-/K+)(C) is found to be 0.319 +/- 0.009(stat)(-0.012)(+0.014)(syst) indicating a larger absorption of K- in heavier targets as compared to lighter ones. The measured phi/K- ratios in pi(-) + C and pi(-) + W reactions within the HADES acceptance are found to be equal to 0.55 +/- 0.04(stat)(-0.07)(+0.06) (syst) and to 0.63 +/- 0.06(stat)(-0.11)(+0.11)(syst), respectively. The similar ratios measured in the two different reactions demonstrate for the first time experimentally that the dynamics of the phi meson in nuclear medium is strongly coupled to the K- dynamics. The large difference in the. production off C and W nuclei is discussed in terms of a strong phi N in-medium coupling. These results are relevant for the description of heavy-ion collisions and the structure of neutron stars.
