An application of the variational analysis to calculate the meson spectral functions
application of the variational analysis calculate the meson spectral functions
2011/1/13
We present a new method to calculate meson spectral functions (SPFs) on the lattice based on
a variational method. Because, on a finite volume lattice, the meson SPFs have discrete spectra
only, a s...
Calculation of $\rho$ meson decay width from the PACS-CS configurations
Calculation $\rho$ meson decay width e PACS-CS configurations
2011/1/13
We present preliminary results on the r meson decay width from Nf = 2+1 full QCD configurations
generated by PACS-CS Collaboration. The decay width is estimated from the P-wave scattering phase shift...
