Massive charged-current coefficient functions in deep-inelastic scattering at NNLO and impact on strange-quark distributions [PDF]

open access: yes, 2017
A bstractWe present details on calculation of next-to-next-to-leading order QCD corrections to massive charged-current coefficient functions in deep-inelastic scattering.

Medium effects in strange quark matter and strange stars [PDF]

open access: yesNucl.Phys. A616 (1997) 659-679, 1996
We investigate the properties of strange quark matter at zero temperature including medium effects. The quarks are considered as quasiparticles which acquire an effective mass generated by the interaction with the other quarks of the dense system. The effective quark masses are derived from the zero momentum limit of the dispersion relations following ...

Strange Quark Stars in Binaries: Formation Rates, Mergers, and Explosive Phenomena [PDF]

open access: yes, 2017
Recently, the possible coexistence of a first family composed of “normal” neutron stars (NSs) with a second family of strange quark stars (QSs) has been proposed as a solution of problems related to the maximum mass and to the minimal radius of these ...

Searching for Strange Quark Matter Objects in Exoplanets [PDF]

open access: yes, 2017
The true ground state of hadronic matter may be strange quark matter (SQM). Consequently, observed pulsars may actually be strange quark stars, but not neutron stars.

Collective modes in strange and isospin asymmetric hadronic matter [PDF]

open access: yesPhys.Lett. B603 (2004) 13-20, 2004
We study the propagation of non-strange and strange meson modes in hadronic matter considering both isospin and strangeness mixings induced by quantum fluctuations in the medium. Baryons are described using the Quark Meson Coupling model extended to include interactions of strange quarks.

NEUTRINO-DRIVEN EXPLOSION OF A 20 SOLAR-MASS STAR IN THREE DIMENSIONS ENABLED BY STRANGE-QUARK CONTRIBUTIONS TO NEUTRINO–NUCLEON SCATTERING [PDF]

open access: yes, 2015
Interactions with neutrons and protons play a crucial role for the neutrino opacity of matter in the supernova core. Their current implementation in many simulation codes, however, is rather schematic and ignores not only modifications for the correlated

An Interview With Peter Rousseeuw

open access: yesInternational Statistical Review, EarlyView.
Summary Peter J. Rousseeuw is a statistician known mainly for his work on robust statistics and cluster analysis. Among his creations are least trimmed squares regression, the minimum covariance determinant estimator, the partitioning around medoids clustering method and the silhouettes graphical display.

Models Of Strange Stars With A Crust And Strange Dwarfs [PDF]

open access: yesAstrofiz. 47 (2004) 223-236, 2004
Strange quark stars with a crust and strange dwarfs consisting of a compact strange quark core and an extended crust are investigated in terms of a bag model. The crust, which consists of atomic nuclei and degenerate electrons, has a limiting density of ro_ cr=ro_drip=4.3*10^11g/cm^3.

Strange Dwarfs: A Review on the (in)Stability

open access: yesUniverse
White dwarfs are the remnants of stars not massive enough to become supernovae. This review explores the concept of strange dwarfs, a unique class of white dwarfs that contain cores of strange quark matter.

Lattice calculation of the leading strange quark-connected contribution to the muon g − 2 [PDF]

open access: yes, 2016
A bstractWe present results for the leading hadronic contribution to the muon anomalous magnetic moment due to strange quark-connected vacuum polarisation effects. Simulations were performed using RBC-UKQCD’s Nf = 2 + 1 domain wall fermion ensembles with
