Herald Fritzsch Libri

Today it is known that the atomic nuclei are composed of smaller constituents, the quarks. A quark is always bound with two other quarks, forming a baryon or with an antiquark, forming a meson. The quark model was first postulated in 1964 by Murray Gell-Mann — who coined the name “quark” from James Joyce's novel Finnegans Wake — and by George Zweig, who then worked at CERN. In the present theory of strong interactions — Quantum Chromodynamics proposed by H Fritzsch and Gell-Mann in 1972 — the forces that bind the quarks together are due to the exchange of eight gluons.On the 50th anniversary of the quark model, this invaluable volume looks back at the developments and achievements in the elementary particle physics that eventuated from that beautiful model. Written by an international team of distinguished physicists, each of whom have made major developments in the field, the volume provides an essential overview of the present state to the academics and researchers.

Murray Gell-Mann, a Nobel Prize-winning physicist, is renowned for his groundbreaking contributions to elementary particle physics, particularly the introduction of quarks. His collaborative work with H. Fritzsch on Quantum Chromodynamics has significantly advanced the understanding of fundamental forces and particles. This book delves into Gell-Mann's theories, exploring their impact on modern physics and how they reshaped our comprehension of the universe's building blocks.

This book provides the readers with a broad introduction to the field of particle physics through fictional discussions between three prominent physicists -- Albert Einstein, Issac Newton, and Murray Gell-Mann -- together with a modern physicist.Matter is composed of quarks and electrons. The forces between quarks are generated by exchanges of gluons and are so strong that they result in the confinement of quarks in atomic nuclei, whereas the forces between electrons and atomic nuclei are generated by exchanges of photons, and the forces between quarks and electrons (or any other leptons) are generated by exchanges of weak bosons.The book is suitable for non-experts in physics.

Exploring the origins and implications of fundamental physical constants, this book features an imaginative dialogue among Isaac Newton, Albert Einstein, and a contemporary physicist. Through their conversation, readers are introduced to key concepts in atomic, nuclear, and particle physics, as well as astrophysics and cosmology. The narrative not only elucidates the nature of constants like the speed of light and Newton's gravity but also engages with profound questions about their constancy over time and space, making complex topics accessible and entertaining.

Neutrino physics is explored through the implications of neutrino oscillations, highlighting their small mass and mixing with charged leptons. The book compiles insights from prominent researchers, addressing critical questions such as the nature of neutrino masses—whether Dirac or Majorana—and the significance of oscillation experiments. Topics include CP-violation in leptons, texture zero mass matrices, and the role of neutrinos in astrophysics and cosmology, reflecting discussions from a recent conference on the state of this intriguing field.

Focusing on the foundations of particle physics, this book delves into the Standard Model, which explains the behavior of electrons and quarks through quantum field theories. It begins with classical and relativistic mechanics before exploring classical scalar fields, electrodynamics, and quantum mechanics. The text further elaborates on the quantization processes for scalar, spinor, and vector fields, providing a comprehensive understanding of the underlying principles that govern the dynamics of matter in the universe.

The book presents an imaginative dialogue among five prominent physicists, including Heisenberg, Feynman, and Newton, exploring the complexities of quantum physics. Through the moderation of Adrian Haller, the discussions delve into the origins of quantum theory, its significance in atomic physics, and its impact on everyday life. The format of questions and answers makes complex concepts accessible to non-physicists, offering insights into the contrasting views of these scientific giants on the nature of reality.

Murray Gell-Mann's groundbreaking contributions to physics are meticulously compiled in this volume, showcasing key concepts such as the strangeness quantum number, the renormalization group, and the quark model. His pivotal work on the SU(3) symmetry and quantum chromodynamics (QCD) is highlighted, alongside important collaborations with notable physicists like Feynman. Additionally, the collection includes Gell-Mann's reflections on the evolution of particle physics during the mid-20th century, making it an essential resource for understanding his impact on the field.
