Lattice QCD estimate of mixing parameters for heavy meson systems

The matrix elements of the two four-fermion operators relevant for the calculation of mixing in the D- D system have been obtained by a lattice QCD calculation in the quenched approximation at β =6.0. The resulting B -parameters are close to each other and not very different from one. The physical i...

description The matrix elements of the two four-fermion operators relevant for the calculation of mixing in the D- D system have been obtained by a lattice QCD calculation in the quenched approximation at β =6.0. The resulting B -parameters are close to each other and not very different from one. The physical implications are discussed, together with a possible extrapolation of the result to the more interesting B- B case.
