Charmed states and flavour symmetry breaking

EPJ Web of Conferences, 2018
Extending the SU(3) flavour symmetry breaking expansion from up, down and strange sea quark masses to partially quenched valence quark masses allows an extrapolation to the charm quark mass.

Determining the strange and antistrange quark distributions of the nucleon

, 2011
The difference between the strange and antistrange quark distributions, $\delta s(x)=s(x)-\sbar(x)$, and the combination of light quark sea and strange quark sea, $\Delta (x)=\dbar(x)+\ubar(x)-s(x)-\sbar(x)$, are originated from non-perturbative ...

DYNAMICAL STABILITY OF STRANGE QUARK STARS [PDF]

International Journal of Modern Physics D, 2011
The necessary and sufficient condition for dynamical stability is worked out for the sequences of relativistic star models which correspond to the well-defined and causal values of adiabatic sound speed, [Formula: see text], at the center. On the basis of the conditions obtained in this study, we show that the mass–radius (M-R) relation corresponding ...

Strange quark matter in a chiral SU(3) quark mean field model

, 2002
We apply the chiral SU(3) quark mean field model to investigate strange quark matter. The stability of strange quark matter with different strangeness fraction is studied.

CLS 2+1 flavor simulations at physical light-and strange-quark masses

EPJ Web of Conferences, 2018
We report recent efforts by CLS to generate an ensemble with physical lightand strange-quark masses in a lattice volume of 192 × 963 at β = 3:55 corresponding to a lattice spacing of 0:064 fm.

The Phase Diagram of High Temperature QCD with Three Flavors of Improved Staggered Quarks

, 2003
We report on progress in our study of high temperature QCD with three flavors of improved staggered quarks. Simulations are being carried out with three degenerate quarks with masses less than or equal to the strange quark mass, $m_s$, and with ...

Quark-Antiquark Condensates in the Hadronic Phase

, 2005
We use a hadron resonance gas model to calculate the quark-antiquark condensates for light (up and down) and strange quark flavors at finite temperatures and chemical potentials.

Seismic search for strange quark nuggets

Physical Review D, 2006
Bounds on masses and abundances of Strange Quark Nuggets (SQNs) are inferred from a seismic search on Earth. Potential SQN bounds from a possible seismic search on the Moon are reviewed and compared with Earth capabilities. Bounds are derived from the data taken by seismometers implanted on the Moon by the Apollo astronauts.

Hawking-Unruh Hadronization and Strangeness Production in High Energy Collisions

Advances in High Energy Physics, 2014
The thermal multihadron production observed in different high energy collisions poses many basic problems: why do even elementary, e+e- and hadron-hadron, collisions show thermal behaviour?
