Baryon Interactions in Nuclear and Hypernuclear Matter
The production and structure of Λ hypernuclei are investigated in field theoretical models. The production in coherent p+A reactions is investigated by means of a resonance model. Results of exploratory calculations for associated strangeness production are presented for proton reactions on 40Ca. The target single particle wave functions are obtained from DDRH theory with density dependent Dira...
متن کاملCharmed Baryon Masses in Chiral Perturbation Theory ∗
The masses of the charmed baryons in the 6 representation of SU(3) obey an equal spacing rule at lowest order in SU(3) breaking, O(ms). We compute the corrections to this relation at order O(m s ) arising from meson loops using chiral perturbation theory combined with heavy quark symmetry and find them to be small. We also examine the hyperfine interaction responsible for the splitting between ...
متن کاملCharmed matter
In the near future experiments will be able to produce charmed hadrons almost at rest in the interior of an atomic nucleus. One of the most exciting perspectives is the possibility of studying charmonium in a dense medium. In the present communication we present results of a study that explores the possibility that J/Ψmight be bound in a large nucleus through the excitation of intermediate stat...

متن کاملSum rules for charmed baryon masses.
The measured masses of the three charge states of the charmed Σc baryon are found to be in disagreement with a sum rule based on the quark model, but relying on no detailed assumptions about the form of the interaction. This poses a significant problem for the charmed baryon sector of the quark model. Other relations among charmed baryon masses are also discussed. PACS numbers: 12.40.Yx., 14.20...
