An Introduction to Quantum Field Theory
by Mrinal Dasgupta
Publisher: University of Manchester 2008
Number of pages: 48
Presently, all observational evidence points to the fact that Quantum Field Theory (QFT) provides a good description of all known elementary particles, as well as for particle physics beyond the Standard Model for energies ranging up to the Planck scale. The scope of these lectures is to provide an introduction to the formalism of Quantum Field Theory.

An introduction to functional integral techniques and how they can be applied in practice. Though we focus on particle physics and cosmology applications, we emphasize that these techniques can be equally applied to other nonequilibrium phenomena.

The book presents a rigorous treatment of the first principles of the algebraic and analytic core of quantum field theory. The authors address readers interested in fundamental mathematical physics and who have the training of a graduate student.

We describe Feynman's path integral approach to quantum mechanics and quantum field theory from a functional integral point of view, where focus lies in Euclidean field theory. Gaussian measure and the construction of the Wiener measure are covered.
