Over the last decade, astrophysical observations of neutron stars — both as isolated and binary sources — have paved the way for a deeper understanding of the structure and dynamics of matter beyond nuclear saturation density. The mapping between astrophysical observations and models of dense matter based on microscopic dynamics has been poorly investigated so far. However, the increased accuracy of present and forthcoming observations may be instrumental in resolving the degeneracy between the predictions of different equations of state. Astrophysical and laboratory probes have the potential to paint to a new coherent picture of nuclear matter — and, more generally, strong interactions — over the widest range of densities occurring in the Universe. This book provides a self-contained account of neutron star properties, microscopic nuclear dynamics and the recent observational developments in multimessenger astronomy. It also discusses the unprecedented possibilities to shed light on long standing and fundamental issues, such as the validity of the description of matter in terms of pointlike baryons and leptons and the appearance of deconfined quarks in the high density regime.

It will be of interest to researchers and advanced PhD students working in the fields of Astrophysics, Gravitational Physics, Nuclear Physics and Particle Physics.

Key Features:

Written by world-leading experts in particle physics, this new book from Luciano Maiani and Omar Benhar, with contributions from the late Nicola Cabibbo, is based on Feynman’s path integrals. Key elements of gauge theories are described—Feynman diagrams, gauge-fixing, Faddeev-Popov ghosts—as well as renormalization in Quantum Electrodynamics. Quarks and QCD interactions are introduced. Renormalization group and high momentum behaviour of the coupling constants is discussed in QED and QCD, with asymptotic freedom derived at one-loop. These concepts are related to the Higgs boson and models of grand unification.

"… an excellent introduction to the quantum theory of gauge fields and their applications to particle physics. … It will be an excellent book for the serious student and a good reference for the professional practitioner. Let me add that, scattered through the pages, we can find occasional traces of Nicola Cabibbo''s style."—John Iliopoulos, CNRS-Ecole Normale Supérieure

" … The volume ends with an illuminating description of the expectation generated by the recent discovery of the Higgs boson, combined with the lack of evidence for super-symmetric particles in the mass range 0.6-1 TeV."—Arturo Menchaca-Rocha, FinstP, Professor of Physics, Mexico’s National Autonomous University, Former President of the Mexican Academy of Sciences, Presidential Advisor

"…The reader is masterfully guided through the subtleties of the quantum field theory and elementary particle physics from simple examples in Quantum Mechanics to salient details of modern theory."—Mikhail Voloshin, Professor of Physics, University of Minnesota

Authored by two of the most respected experts in the field of nuclear matter, this book provides an up-to-date account of developments in nuclear matter theory and a critical comparison of the existing theoretical approaches in the field.

It provides information needed for researchers working with applications in a variety of research fields, ranging from nuclear physics to astrophysics and gravitational physics, and the computational techniques discussed in the book are relevant for the broader condensed matter and quantum fluids community.

Questo libro si propone di fornire un''introduzione, allo stesso tempo accessibile e completa, alle stelle compatte. Dopo una prima parte dedicata alla fisica delle nane bianche, nella parte centrale del volume vengono analizzate la struttura e la dinamica delle stelle di neutroni. Particolare attenzione è rivolta ai modelli utilizzati per la descrizione della materia stellare a livello microscopico. Questi modelli sono altamente multidisciplinari, in quanto abbracciano campi di ricerca che vanno dalla fisica nucleare e delle particelle elementari alla fisica della materia condensata all''astrofisica. Tutti gli argomenti sono trattati con un approccio pedagogico, facendo riferimento allo sviluppo storico delle osservazioni astronomiche e degli studi teorici. Ampio spazio è dedicato alla discussione dell''impatto dei risultati sperimentali più recenti, come la rivelazione di onde gravitazionali, e dei dati senza precedenti che saranno disponibili nella nascente era dell''astronomia multimessaggera. Questo volume vuole offrire agli studenti di dottorato in fisica ed astrofisica delle solide basi per la loro futura carriera scientifica. I ricercatori già impegnati nei campi della fisica nucleare e delle particelle, così come nell''astrofisica a nella fisica gravitazionale, lo troveranno un utile strumento di consultazione.
