The production of K + -mesons in pA (A = D, C, Cu, Ag, Au) collisions has been investigated at the COoler SYnchrotron COSY-Jülich for beam energies Tp = 1.0 − 2.3 GeV. Double differential inclusive p C cross sections at forward angles ϑ K + < 12 • as well as the target-mass dependence of the K +momentum spectra have been measured with the ANKE spectrometer. Far below the free N N threshold at TNN = 1.58 GeV the spectra reveal a high degree of collectivity in the target nucleus. From the targetmass dependence of the cross sections at higher energies, the repulsive in-medium potential of K + -mesons can be deduced. Using pN cross-section parameterisations from literature and our measured p D data we derive a cross-section ratio of σ(pn → K + X)/σ(pp → K + X) ∼ (3 − 4).

“…In a recent publication [16] we showed that the measured invariant cross sections E d 3 σ/d 3 p follow an exponential scaling behavior when plotted as a function of the four-momentum transfer t, which is illustrated in Fig.2 (l.h.s.). The data from LBL [10] and ITEP [13,14] were measured with N aF (Be) targets and have been corrected for the targetmass dependence according to Ref. [16].…”

The production of K + -mesons in pA (A = C, Cu, Ag, Au) collisions has been investigated at the COoler SYnchrotron COSY-Jülich at beam energies T p = 1.0 . . . 2.3 GeV using the ANKE spectrometer. ANKE allows to measure double differential cross sections for K + -production at forward angles ϑ < 12 • in a wide momentum range. The cross sections obtained in these experiments together with those from literature show a uniform behavior as functions of momentum transfer and excitation energy of the residual nucleus. At the lowest measured beam energy, far below the free N N -threshold (T N N = 1.58 GeV), the data reveal a high degree of collectivity in the target nucleus. The spectra obtained above threshold should allow one to extract the nuclear K + -potential with an accuracy of better than ±3 MeV. Information about the mechanisms leading to K +production can be obtained from K + p and K
