Field Theory: A Modern Primer

This book presents recent advances in perturbative relativistic field theory in a straightforward manner, covering topics from building action functionals and the Lorentz/Poincaré groups to path integrals, fermions, gauge symmetries like Yang-Mills and gravity, and perturbative evaluations.

It includes detailed chapters on Feynman path integrals, φ⁴ theory, QED, and Yang-Mills theory with asymptotic freedom, aimed at students specializing in high-energy physics.
