The most non-trivial of the established microscopic theories of physics is QCD the theory of the strong interaction. A critical link between theory and experiment is provided by the methods of perturbative QCD, notably the well-known factorization theorems. Giving an accurate account of the concepts, theorems, and their justification, this book is a systematic treatment of perturbative QCD. As …
Heavy ion collision experiments recreating the quark–gluon plasma that filled the microseconds-old Universe have established that it is a nearly perfect liquid that flows with such minimal dissipation that it cannot be seen as made of particles.
The electroweak theory unifies two basic forces of nature the weak force and electromagnetism. This achievement is comparable to Maxwell’s unification of electricity and magnetism. The theory made numerous predictions that have been confirmed by experiments.
