| 英文摘要 | The total cross-section for the dd -> He-4 K+K- reaction has been measured at a beam momentum of 3.7 GeV/c, corresponding to an excess energy of 39 MeV, which is the maximum possible at the Cooler Synchrotron COSY-Julich. A deuterium cluster-jet target and the ANKE forward magnetic spectrometer, placed inside the storage ring, have been employed in this investigation. We find a total cross-section of sigma(tot) < 14 pb, which brings into question the viability of investigating the dd -> He-4 a(0)(980) reaction as a means of studying isospin violation. |
