Nucleon strange quark content from two-flavor lattice QCD with exact chiral symmetry
Nucleon strange quark content two-flavor lattice QCD exact chiral symmetry
2011/1/13
Strange quark content of the nucleon hN|¯ss|Ni is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginspar...
The state of the art in dibaryons with strangeness is reviewed, including the K−pp dibaryon which signals the onset of ¯K –nuclear binding. A new type of strange dibaryons is highlighted, w...
