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.
