Scaling study for 2 HEX smeared fermions: hadron and quark masses
Scaling study 2 HEX smeared fermions hadron
2011/1/6
The goal of this study is to investigate the scaling behaviour of our 2 HEX action. For this purpose, we compute the $N_f=3$ spectrum and compare the results to our 6 EXP action. We find a large scali...

Analysis of the $N_f=2+1$ lattice QCD results on the lowest-lying baryon masses using covariant ChPT
the $N_f=2+1$ lattice QCD results lowest-lying baryon masses
2011/1/6
We review recent progress in the understanding of low-energy baryon structure by means of chiral perturbation theory. In particular, we discuss the application of this formalism to the description of ...

Ordinary matter is described by six fundamental parameters: three couplings (gravitational, electromagnetic and strong) and three masses: the electron's ($m_e$) and those of the up ($m_u$) and down ($...

We present the results of the recent high precision lattice calculation of the average up/down, strange and charm quark masses performed by ETMC with Nf=2 twisted mass Wilson fermions. The analysis in...

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...

Two flavor QCD involves three independent mass parameters for which non-perturbative effects are not universal. This precludes matching lattice and perturbative results for non-degenerate quarks and e...
Strong coupling，charm- and bottom-quark masses from electron-positron annihilation
strong coupling quark masses
2010/5/7
The cross section for electron-positron annihilation into hadrons allows for a precise determination of the strong coupling constant and the charm- and bottom-quark masses. Recent theoretical and expe...
Effect of current quark masses on quark phase transitions in supernovae
quark phase transition current quark mass supernova
2009/8/14
The current quark mass model is adopted to study the phase transition of two-flavor quark matter to more stable three-flavor quark matter in the whole core of a supernova. It shows that the timescale ...

We introduce and summary our research progress on the effective masses of K meson in dense nuclear matter.
Masses of Charged Leptons and Gauge Mixing Parameters
Charged lepton masses mixing parameters Gauge models
2010/4/9
It is shown that the electroweak physics of the electron and the muon is based on the left-right gauge model with the mixing parameters 0.2254 and 0.2746. These mixing parameters are determined by the...
