Hyperon resonances and K− production at SIS
In a recent work Hartnack, Oeschler and Aichelin [1] studied the possible importance of in-medium modified πY → K̄N cross sections in subthreshold K− production at SIS. Within their scenario, which does not consider a momentum dependence of the antikaon mean field nor a proper treatment of the spectral distributions of hadrons, they observe an enhancement of the K− yield by a factor 2 if the πY ...
متن کاملDiiractive Charged Meson Pair Production
We investigate the possibility to measure the nonforward gluon distribution function by means of diiractively produced + ? and K + K ? pairs in polarized lepton nucleon scattering. The resulting cross sections are sizable and are dominated by the gluonic contribution. We nd large spin asymmetries, both for + ? and for K + K ? pairs.
متن کاملhyperon production at COSY
COSY with a maximum beam momentum of ∼ 3.65 GeV/c allows the production of ground state (Λ and Σ) and excited hyperons (Λ(1405), Σ(1385) and Λ(1520) ) in elementary NN interactions. The existing data base in this field is rather poor. A systematic study of the hyperon production at COSY will result in an improvement of our understanding concerning topics like hyperon–nucleon interaction, kaon–n...
متن کاملInclusive K-meson production in proton-nucleus interactions
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 pC cross sections at forward angles θK+ < 12 ◦ as well as the target-mass dependence of the Kmomentum spectra have been measured with the ANKE spectrometer. Far below the free NN threshold at TNN = 1.58...
متن کاملCharge Properties of the K Meson and Hyperon Decay Interaction
The question of the AT involved in strange-particle decays is discussed in terms of universal Fermi interactions. The fundamental interactions considered contain b, T&—, as suggested by both experimental and purely theoretical considerations. It is found that by assuming global symmetry in both the pion coupling and the weak coupling one may restrict the AT to —, in a class of processes involve...
