Written by two of the most prominent leaders in particle physics, Relativistic Quantum Mechanics: An Introduction to Relativistic Quantum Fields provides a classroom-tested introduction to the formal and conceptual foundations of quantum field theory.

Luciano Maiani, born in 1941, is emeritus professor of theoretical physics

at the University of Rome, \La Sapienza", and author of more than two hundred

scienti_c publications on the theoretical physics of elementary particles.

He, together with S. Glashow and J. Iliopoulos, made the prediction of a new

family of particles, those with \charm", which form an essential part of the

uni_ed theory of the weak and electromagnetic forces. He has been president

of the Italian Institute for Nuclear Physics (INFN), Director-General of

CERN in Geneva and president of the Italian National Council for Research

(CNR). He promoted the development of the Virgo Observatory for gravitational

wave detection, the neutrino beam from CERN to Gran Sasso and at

CERN directed the crucial phases of the construction of the Large Hadron

Collider. He has taught and worked in numerous foreign institutes. He was

head of the theoretical physics department at the University of Rome, \La

Sapienza", from 1976 to 1984 and held the chair of theoretical physics from

1984 to 2011. He is a member of the Italian Lincean Academy and a Fellow

of the American Physical Society.

Omar Benhar, born in 1953, is an INFN research director and teaches gauge

theories at the University of Rome, \La Sapienza". He has worked extensively

in the USA as visiting professor, at the University of Illinois and the Old

Dominion University, as well as associate scientist at the Thomas Je_erson

National Accelerator Facility. Since 2013, he has served as an adjunct professor

at the Centre for Neutrino Physics of Virginia Polytechnic Institute and

State University. He is the author of more than a hundred scienti_c papers

on the theory of many-particle systems, the structure of compact stars and

electroweak interactions of nuclei.
