Jiří Hořejší Bücher

This monograph of Prof. Horejší is based on a series of his lectures which took place at Faculty of Mathematics and Physics of Charles University during 1990s. The author gives a thorough and easy-to-read account of the basic principles of the standard model of electroweak interactions, describes various theories of electromagnetic and weak interactions, and explains the gauge theory of electroweak interactions. Five appendices expound on some special techniques of the Standard Model, used in the main body of the text. Thanks to the author's pedagogical skills and professional erudition, the book can be read just with a preliminary knowledge of quantum field theory.

The material presented encompasses a two-semester course in quantum field theory taught by the author for over two decades at Charles University and Czech Technical University in Prague. It explores selected topics in relativistic quantum mechanics and quantum field theory, with a primary focus on quantum electrodynamics. Detailed discussions include Feynman diagrams, regularization, and renormalization methods, along with fundamental applications. The chosen topics aim to equip readers with the technical skills essential for further studies in theoretical particle physics. The text features numerous explicit calculations that are less common in other sources, reflecting the content of the author's lectures. While primarily intended for university students specializing in theoretical physics or nuclear and particle physics, the work is also valuable for any scientifically-minded reader interested in the foundations of modern physics. The book was published in collaboration with Karolinum Press of Charles University.

This book is based on the lecture course taught by the author for about three decades at Charles University. The author gives a thorough and easy-to-read account of the basic principles of the standard model of electroweak interactions, describes various theories of electromagnetic and weak interactions, and explains the gauge theory of electroweak interactions. The criterion of the tree-level unitarity is used throughout the text to check the gradual steps leading to the renormalizable electroweak theory. Five appendices expound on some special techniques of the Standard Model, used in the main body of the text. The book can be read with just a preliminary knowledge of quantum field theory. In comparison with the first edition of the book published more than 20 years ago, new passages concerning the Higgs boson are added, as well as some new problems and solutions.

Kniha poměrně podrobně popisuje cestu k současnému standardnı́mu modelu částicové fyziky, od objevů elektronu, atomového jádra a radioaktivity až po slavný Higgsův boson, který v nedávné době upoutal pozornost i širšı́ laické veřejnosti. Text má popularizačnı́ charakter a proto obsahuje jen naprosté minimum jednoduchých matematických formulı́. Je určen všem zájemcům o částicovou fyziku. Užitek z něj tak mohou mı́t napřı́klad studenti nejvyššı́ch ročnı́ků střednı́ch škol, studenti přı́rodovědných a technických oborů vysokých škol, středoškolštı́ učitelé matematiky a fyziky, badatelé v jiných oborech usilujı́cı́ o širšı́ rozhled po současné fyzice, ale jistě i mnozı́ dalšı́ zájemci o hlubšı́ poznánı́ struktury hmoty na současné úrovni.
