The different ground state energies of N-pion and M-kaon systems for N+M <=12 are studied in lattice QCD. These energies are then used to extract the various two- and three- body interactions that occur in these systems. Particular…

The QCD phase transition is studied on 32^3x8 quenched lattices. One expects from simple arguments that the quenched chiral condensate should diverge as the chiral limit is approached. Previous studies have not been able to observe this…

Non-perturbative lattice studies of QCD in the chiral thermodynamic regime, where chiral symmetry is spontaneously broken, require to deal with almost quark zero modes in a theoretically clean and computationally efficient way. We discuss…
