Baryon-Baryon Potentials on the Lattice [PDF]

Phys.Lett. B318 (1993) 507-510, 1993
The interaction of spatially extended heavy baryons is investigated in the framework of lattice QCD with dynamical quarks. It is shown that the expected dipole forces have a very short range and that the baryon-antibaryon interaction is more attractive than the baryon-baryon interaction. Sea quarks play a minor important role.

Baryon Operators and Baryon Spectroscopy [PDF]

Nuclear Physics B - Proceedings Supplements, 2006
The issues involved in a determination of the baryon resonance spectrum in lattice QCD are discussed. The variational method is introduced and the need to construct a sufficient basis of interpolating operators is emphasised.

Baryon-Baryon Interactions [PDF]

, 1994
After a short survey of some topics of interest in the study of baryon-baryon scattering, the recent Nijmegen energy dependent partial wave analysis (PWA) of the nucleon-nucleon data is reviewed. In this PWA the energy range for both pp and np is now 0 <

Soft-core baryon-baryon potentials for the complete baryon octet [PDF]

Physical Review C, 1999
SU(3) symmetry relations on the recently constructed hyperon-nucleon potentials are used to develop potential models for all possible baryon-baryon interaction channels.

Detecting a First-Order Transition in the QCD Phase Diagram with Baryon-Baryon Correlations [PDF]

Phys.Lett.B690:135-140, 2010, 2009
We suggest baryon-baryon correlations as an experimentally accessible signature for a first-order phase transition between a baryon-rich phase, like quarkyonic, and a baryon-suppressed hadronic phase in the QCD phase diagram. We examine the consequences of baryon-rich bubble formation in an expanding medium and show how the two-particle correlations ...

Strangeness S=-3 and -4 baryon-baryon interactions in chiral EFT [PDF]

, 2010
I report on recent progress in the description of baryon-baryon systems within chiral effective field theory. In particular, I discuss results for the strangeness S=-3 to -4 baryon-baryon systems, obtained to leading order.

Baryon Production in the String Fragmentation Picture [PDF]

Z.Phys. C75 (1997) 41-49, 1996
An improved version of the ``pop-corn'' model for baryon production in quark and gluon jets is presented. With a reduced number of parameters the model reproduces well both production rates for different baryon species and baryon momentum distributions. Predictions are presented for a set of baryon-antibaryon correlations.

Lattice QCD at finite baryon density using analytic continuation

EPJ Web of Conferences, 2018
We simulate lattice QCD with two flavors of Wilson fermions at imaginary baryon chemical potential. Results for the baryon number density computed in the confining and deconfining phases at imaginary baryon chemical potential are used to determine the ...

Hadron resonance gas with repulsive interactions and fluctuations of conserved charges

Physics Letters B, 2018
We discuss the role of repulsive baryon–baryon interactions in a hadron gas using relativistic virial expansion and repulsive mean field approaches. The fluctuations of the baryon number as well as strangeness-baryon correlations are calculated in the ...
