Recent results on ρ(770), K(892), f0(980), φ(1020), ∆(1232) , and Λ(1520) production in A+A and p + p collisions at SPS and RHIC energies are presented. These resonances are measured via their hadronic decay channels and used as a sensitive tool to examine the collision dynamics in the hadronic medium through their decay and regeneration. The modification of resonance mass, width, and shape due...

The first measurement of the pn → dω total cross section has been achieved at mean excess energies of Q ≈ 26 and 60MeV by using a deuterium cluster-jet target. The momentum of the fast deuteron was measured in the ANKE spectrometer at COSY-Jülich and that of the slow “spectator” proton (psp) from the pd → pspdω reaction in a silicon telescope placed close to the target. The cross sections lie a...

A dispersive optical model analysis of p+Ca and p+Ca interactions has been carried out. The real and imaginary potentials have been constrained from fits to elastic scattering data, reaction cross sections, and level properties of valence hole states deduced from (e, e′p) data. The surface imaginary potential was found to be larger overall and the gap in this potential on either side of the Fer...
