The K^- αscattering length and the reaction dd \to αK^+ K^-
V. Yu. Grishina, L. A. Kondratyuk, A. Sibirtsev +4
We present predictions for the the K^- αscattering length obtained within the framework of the multiple scattering approach. Evaluating the pole position of the K^- αscattering amp…
Density Matrix Functional Theory with account of pairing correlations
S. Krewald, V. B. Soubbotin, V. I. Tselyaev +1
The extension of the density functional theory (DFT) to include pairing correlations without formal violation of the particle-number conservation condition is described. This versi…
Determination of the \bar K^0 d scattering length from the reaction pp \to d \bar K^0 K^+
A. Sibirtsev, M. Büscher, V. Yu. Grishina +4
The real and imaginary parts of the \bar K^0 d scattering length are extracted from the \bar K^0 d mass spectrum obtained from the reaction pp \to d \bar K^0 K^+ measured recently…
Indication of anomalous exchange in exclusive charmonium photoproduction
A. Sibirtsev, S. Krewald, A. W. Thomas
We find that available data on photoproduction at 1 GeV are energy independent over the range GeV and show a very soft dependence. Thr…
Charmonium photoproduction
A. Sibirtsev, S. Krewald, A. W. Thomas
The available data on photoproduction are analyzed in terms of pomeron exchange, two gluon exchange and photon-gluon fusion models. Allowing the pomeron-quark interaction to…
Omega photoproduction beyond the resonance region at small u
A. Sibirtsev, K. Tsushima, S. Krewald
Within the meson exchange model we study meson photoproduction at energies above the s channel resonance region. Different model prescriptions for the vertex function a…
