We describe and test a method known in the literature as low mode averaging to improve Euclidean two-point functions in lattice QCD using the low-lying eigenmodes of the Wilson-Dirac operator D. The c...

Heavy-Quark Mass and Heavy-Meson Decay Constants from QCD Sum Rules
Heavy-Quark Mass Heavy-Meson Decay Constants
2011/1/7
We present a sum-rule extraction of heavy-meson decay constants from the two-point correlator of heavy-light pseudoscalar currents. Our main concern is to control the uncertainties of the decay consta...
Calculation of $\rho$ meson decay width from the PACS-CS configurations
meson decay width the PACS-CS configurations
2011/1/6
We present preliminary results on the $\rho$ meson decay width from $N_f=2+1$ full QCD configurations generated by PACS-CS Collaboration. The decay width is estimated from the $P$-wave scattering phas...

We introduce and summary our research progress on the effective masses of K meson in dense nuclear matter.
Feasibility study for the measurement of Bc meson mass and lifetime with the general purpose detector at the LHC
Bc mass lifetime LHC general purpose detector
2009/7/31
In this paper a feasibility study of the Bc meson to measure its mass and lifetime is described with the general purpose detector at the LHC. The study solely concentrated on the J/ψπ+, J/ψ→μ+μ－ deca...
