چکیده
I discuss the latest progress in calculating baryon-baryon interactions with lattice QCD. The latest results from the NPLQCD collaboration for nucleon-nucleon scattering along with preliminary calculations of hyperon-nucleon scattering are presented.

Nuclear force in Lattice QCD
We perform the quenched lattice QCD analysis on the nuclear force (baryon-baryon interactions). We employ 203 ×24 lattice at β = 5.7 (a ≃ 0.19 fm) with the standard gauge action and the Wilson quark action with the hopping parameters κ = 0.1600,0.1625,0.1650, and generate about 200 gauge configurations. We measure the temporal correlators of the two-baryon system which consists of heavy-light-l...
متن کاملMeson-Meson and Meson-Baryon Interactions in Lattice QCD
We study the meson-meson and meson-baryon interactions in lattice QCD. The simulation is performed on 203 × 24 lattice at β = 5.7 using Wilson gauge action and Wilson fermion at the quenched level. By adopting one static quark for each hadron as “heavy-light meson" and “heavy-light-light baryon", we define the distance r of two hadrons and extract the inter-hadron potential from the energy diff...
متن کاملSome Remarks on the Baryon-Meson Couplings in the 1/Nc Expansion
The original results for the baryon-pion couplings in the large Nc QCD can be understood in a simpler way in the Hartree-Fock picture. The large Nc relation and its 1/Nc correction between the heavy baryonmeson coupling and the light baryon-meson coupling are emphasized. Application to the baryon-ρ meson interactions is straightforward. The implications of recent experimental result for the str...
متن کاملStatic potential in baryon
The baryon static potential is calculated in the framework of field correlator method and is shown to match the recent lattice results. The effects of the nonzero value of the gluon correlation length are emphasized. 1. The static potential is a key quantity in the calculations of spectra and wave functions of baryons in the potential models [1], as well as in the QCD string approach [2]. On th...
متن کاملThe QCD Mixed Phase: Shaken, not Stirred
If the phase transition from quark matter to hadron gas is first order, matter at the appropriate temperatures and densities can exist as a mixed phase consisting of plasma droplets in equilibrium with a surrounding hadronic fluid. If formed in ion collisions, this mixed phase can produce large event-by-event fluctuations as the system hadronizes. Extraordinary baryon fluctuations [1] can accom...
