Teaching about the birth of synchrotron light: the role of Frascati and a missed opportunity

Journal of Synchrotron Radiation, Volume 31, Issue 4, Page 987-998, July 2024.
A collection of personal reminiscences illuminates many widely unknown facts about the first steps of synchrotron radiation research; in particular, the events that brought Frascati close to world leadership in this domain.The users of synchrotron light are now tens of thousands throughout the world.

Stellar model with non-zero strange quark mass ( $$m_s\ne 0$$ m s ≠ 0 ) and Mak–Harko density profile admitting observational results

European Physical Journal C: Particles and Fields
This article describes the configuration of strange quark stars composed of three flavour quarks in hydrostatic equilibrium considering the energy density profile of Mak and Harko and non-zero strange quark mass ( $$m_s\ne {0}$$ m s ≠ 0 ).

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.

String breaking by light and strange quarks in QCD

Physics Letters B, 2019
The energy spectrum of a system containing a static quark anti-quark pair is computed for a wide range of source separations using lattice QCD with Nf=2+1 dynamical flavours.

Strange quarks in quenched twisted mass lattice QCD

, 2006
Two twisted doublets, one containing the up and down quarks and the other containing the strange quark with an SU(2)-flavor partner, are used for studies in the meson sector.

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 ...

A Three-Flavor AdS/QCD Model with a Back-Reacted Geometry

, 2007
A fully back-reaction geometry model of AdS/QCD including the strange quark is described. We find that with the inclusion of the strange quark the impact on the metric is very small and the final predictions are changed only negligibly.Comment: 10 pages,

Strange quark matter and compact stars [PDF]

Progress in Particle and Nuclear Physics, 2005
Astrophysicists distinguish between three different types of compact stars. These are white dwarfs, neutron stars, and black holes. The former contain matter in one of the densest forms found in the Universe which, together with the unprecedented progress in observational astronomy, make such stars superb astrophysical laboratories for a broad range of

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.

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.
