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...

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...

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 ...
