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…
Near threshold enhancement of the ppbar mass spectrum in J/Psi decay
A. Sibirtsev, J. Haidenbauer, S. Krewald +2
We investigate the nature of the near-threshold enhancement in the ppbar invariant mass spectrum of the reaction J/Psi -> gamma ppbar reported recently by the BES Collaboration. Us…
Proposal for the Wide Angle Shower Apparatus (WASA) at COSY-Juelich - "WASA at COSY"
COSY Collaboration, B. Hoistad, J. Ritman
This document describes the physics case, the key experiments proposed and the technical solution for the project "WASA at COSY", which concerns the transfer of the WASA pellet-tar…
Analysis of Theta^+ production in K^+Xe collisions
A. Sibirtsev, J. Haidenbauer, S. Krewald +1
The reaction K^+Xe->K^0pX is investigated in a meson-exchange model including rescattering of the secondary protons with the aim to analyze the evidence for the Theta^+(1540) reson…
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…
New results on the limit for the width of the exotic Theta^+ resonance
A. Sibirtsev, J. Haidenbauer, S. Krewald +1
We investigate the impact of the Θ^+(1540) resonance on differential and integrated cross sections for the reaction K^+d{\to}K^0pp, where experimental information is available at k…
