The basic problem in formulating a quantum theory of gravity was already recognized ... the problem was confirmed explicitly in the first Feynman-diagram calculations of the radiative corrections ...

The Standard Model is a gauge theory that describes the strong, weak, and electromagnetic forces, and it has specific ...

This book presents a comprehensive and coherent account of the theory of quantum fields on a lattice, an essential technique for the study of the strong and the electroweak interactions of elementary ...
