Superbursts from Strange Stars [PDF]

, 2005
Recent models of carbon ignition on accreting neutron stars predict superburst ignition depths that are an order of magnitude larger than observed. We explore a possible solution to this problem, that the compact stars in low mass X-ray binaries that ...

Enhancement of singly and multiply strangeness in p-Pb and Pb-Pb collisions at 158A GeV/c [PDF]

, 1999
The idea that the reduction of the strange quark suppression in string fragmentation leads to the enhancement of strange particle yield in nucleus-nucleus collisions is applied to study the singly and multiply strange particle production in p-Pb and Pb ...

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

, 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 ...

Strange Exotic States and Compact Stars [PDF]

, 2006
We discuss the possible appearance of strange exotic multi-quark states in the interior of neutron stars and signals for the existence of strange quark matter in the core of compact stars.

Strangeness counting in high energy collisions [PDF]

, 1998
The estimates of overall strange quark production in high energy e+e-, pp and ppbar collisions by using the statistical-thermal model of hadronisation are presented and compared with previous works.

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

, 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

Thermal Evolution and Light Curves of Young Bare Strange Stars [PDF]

, 2002
The cooling of a young bare strange star is studied numerically by solving the equations of energy conservation and heat transport for both normal and superconducting strange quark matter inside the star.

Strangeness in Astrophysics and Cosmology

, 2010
Some recent developments concerning the role of strange quark matter for astrophysical systems and the QCD phase transition in the early universe are addressed.

Non-perturbative structure of the polarized nucleon sea

, 2003
We investigate the flavour and quark-antiquark structure of the polarized nucleon by calculating the parton distribution functions of the nucleon sea using the meson cloud model. We find that the SU(2) flavor symmetry in the light antiquark sea and quark-

Light Quark Masses with Dynamical Wilson Fermions [PDF]

, 1997
We determine the masses of the light and the strange quarks in the $\bar{MS}$-scheme using our high-statistics lattice simulation of QCD with dynamical Wilson fermions. For the light quark mass we find $m^{light}_{\bar{MS}}(2 GeV) = 2.7(2) MeV$, which is
