This introductory text begins with a review of the Standard Model, followed by the basics of heavy quark spin-flavor symmetry and its application to the classification of states, decays and ...

It all started with a Big Bang – and now scientists are on a quest to unravel the mystery behind the birth of the universe.

The maximal densities of the current quarks: strange (s), charm (c), bottom (b), and top (t) resulted in the range (0.8 - 4.2) × 1018 kg/m3, as values which could be specific to possible quark stars, ...

quark stars and hybrid stars. The author discusses in depth the theory underpinning our understanding of these objects (general relativity and the thermodynamics of dense matter) but also presents ...

When NASA's Voyager 2 spacecraft flew by Uranus in 1986, it provided scientists' first—and, so far, only—close glimpse of this strange, sideways-rotating outer planet. Alongside the discovery ...

The perspectives offered by these discoveries could revolutionize nuclear physics and pave the way for new experiments to unlock the secrets of matter. A quark is an elementary particle that makes up ...

Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and space ...

Astronomy and planetary science are the study of objects and phenomena that occur beyond the Earth’s atmosphere. This includes investigating stars and their interaction with each other and the ...
