We evaluate the antikaon spectral density in isospin symmetric nuclear matter. The in-medium antikaon-nucleon scattering process and the antikaon propagation is treated in a self consistent and relativistic manner where a maximally schemeindependent formulation is derived by performing a partial density resummation in terms of the free-space antikaon-nucleon scattering amplitudes. The latter am...

The FOPI Collaboration performed a high statistic experiment to study the strangeness production in Al+Al collisions at 1.9A GeV. The high statistics data (300 million of events) allow the reconstruction of the Σ(1385) hyperon resonance at SIS energies for the first time. This measurement corresponds to sub-threshold production since the threshold beam energy for Σ∗ production in the elementary...

OBJECTIVE The direct trocar technique is an alternative to Veress needle insertion and open laparoscopy for accessing the abdominal cavity for operative laparoscopy. We review our approach to abdominal entry in 1385 laparoscopies performed between September 1993 and June 2000 by our group at Stanford University Hospital, a tertiary Medical Center. METHODS We performed a retrospective chart re...

out the whole region will provide a final answer to the spin question and information on the parity. In particular, the energy dependence of the Z w+ differential cross sections must be established carefully, because we cannot rule out the possibility that the large value of A, (Z ~+) at 760 MeV/c is due mainly to nonresonant terms. If this is the case, the value of x& would be much smaller, an...
