Light Quark Masses from Lattice QCD
We present estimates of the masses of light quarks using lattice data. Our main results are based on a global analysis of all the published data for Wilson and Staggered fermions, both in the quenched approximation and with nf = 2 dynamical flavors. We find that the values of masses in the Wilson and Staggered formulations agree after extrapolation to the continuum limit for both the nf = 0 and...

متن کاملNeutron Star Masses, Radii and Equation of State
We are closing in on neutron stars both observationally and theoretically. Observationally, a number of masses (M) and a few radii (R) have been measured as well as a number of other properties. Theoretically, modern equation of states (EOS) are more reliable due to precision measurements of nucleon-nucleon interactions, detailed calculations of binding energies of light nuclei and nuclear matt...
متن کاملConstraints on Neutron Star Masses and Radii from Kilohertz QPOs
The frequencies of the highest-frequency kilohertz QPOs recently discovered in some sixteen neutron stars in low-mass X-ray binary systems are most likely orbital frequencies. If so, these QPOs provide tight upper bounds on the masses and radii of these neutron stars and interesting new constraints on the equation of state of neutron star matter. If the frequency of a kilohertz QPO can be estab...
متن کاملCompatibility of neutron star masses and hyperon coupling constants
It is shown that the modern equations of state for neutron star matter based on microscopic calculations of symmetric and asymmetric nuclear matter are compatible with the lower bound on the maximum neutron-star mass for a certain range of hyperon coupling constants, which are constrained by the binding energies of hyperons in symmetric nuclear matter. The hyperons are included by means of the ...
