Strange Quark Magnetic Moment of the Nucleon at Physical Point [PDF]

open access: yes, 2017
We report a lattice QCD calculation of the strange quark contribution to the nucleon's magnetic moment and charge radius. This analysis presents the first direct determination of strange electromagnetic form factors including at the physical pion mass ...

Quark Matter May Not Be Strange [PDF]

open access: yesPhysical Review Letters, 2018
If quark matter is energetically favored over nuclear matter at zero temperature and pressure then it has long been expected to take the form of strange quark matter (SQM), with comparable amounts of $u$, $d$, $s$ quarks. The possibility of quark matter with only $u$, $d$ quarks ($ud$QM) is usually dismissed because of the observed stability of ...

GW emission from merging strange quark star-strange quark planet systems [PDF]

open access: yesAIP Conference Proceedings, 2019
Strange quark matter (SQM) may be the true ground state of hadronic matter. The observed pulsars may actually be strange quark stars, rather than neutron stars. With such an SQM hypothesis, researchers have predicted the existence of hydrostatically stable sequence of strange quark stars, like strange quark dwarfs and even strange quark planets ...

Quark, pion and axial condensates in three-flavor finite isospin chiral perturbation theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We calculate the light-quark condensate, the strange-quark condensate, the pion condensate, and the axial condensate in three-flavor chiral perturbation theory ( $$\chi $$ χ PT) in the presence of an isospin chemical potential at next-to-leading order at

On the estimation of the strange quark mass from the experimental data on the light baryon octet

open access: yesЯдерна фізика та енергетика, 2018
Simple relations connecting the strange quark mass to the splittings of the light hyperon masses were obtained on the basis of the phenomenological quark model compatible with the present-day theory of strong interactions, i.e.

Transition temperature in QCD with physical light and strange quark masses [PDF]

open access: yes, 2006
We present results from a calculation of the transition temperature in QCD with two light and one heavier (strange) quark mass on lattices with temporal extent N_t =4 and 6. Calculations with improved staggered fermions have been performed with a strange

Strange Quark Stars — A Review [PDF]

open access: yesSymposium - International Astronomical Union, 2003
A pedagogical overview of strange quark matter and strange stars is presented. After a historical notation of the research and an introduction to quark matter, a major part is devoted to the physics and astrophysics of strange stars, with attention being paid to the possible ways by which neutron stars and strange stars can be distinguished in ...

Discriminating hadronic and quark stars through gravitational waves of fluid pulsation modes [PDF]

open access: yes, 2013
We investigate non-radial oscillations of hadronic, hybrid and pure self-bound strange quark stars with maximum masses above the mass of the recently observed massive pulsars PSR J1614-2230 and PSR J0348-0432 with $M \approx 2 M_{\odot}$.

Quark condensates and strange quark matter [PDF]

open access: yesPhysical Review C, 1997
Based upon recent studies on quark condensates, we investigate strange quark matter at zero temperature and find that the mass parametrization popularly used for u/d quarks with the mass-density-dependent model is just a first-order approximation to a more general formula, whereas the corresponding formula for s quarks has to be modified, which leads ...
