It just happened that it was the time between two significant dates: in 2011 the Nobel Prize was awarded “for the discovery of the accelerated expansion of the Universe through observations of distant Supernovae” and in 2013 the Nobel Prize was awarded for “the theoretical discovery of a mechanism that contributes to our understanding of the origin of the mass of subatomic particles”. Both these formulations left the questions about the explanations of these phenomena in the framework of the fundamental principles open. Our book is devoted to attempts to explain the observed long dis- tances to the Supernovae and the small value of the Higgs particle mass by the principles of affine and conformal symmetries and the vacuum postulate. Both these phenomena are described by quantum gravity in the form of joint irreducible unitary representations of the affine and con- formal symmetry groups. These representations were used in our book to classify physical processes in the Universe, including its origin from the vacuum. The representations of the Poincar´egroup were used in the same way by Wigner to classify particles and their bound states. We are far from considering our understanding of the “distant Super- novae” and the “origin of the mass of subatomic particles” to be conclu- sive, but we do not abandon hope that the present revised and enlarged English edition encourages a deeper and worthier investigation of these open questions in the future.

Pavlov December, 2013 Dubna Preface to the first Russian edition1 This monograph is based on papers published during last 25 years by the authors and lectures delivered by one of the authors (V.P.) at the universities of Graz (Austria), Berlin, Heidelberg, Rostock (Germany), New Delhi (India), Fairfield, the Argonne National Laboratory (USA), the physical faculty of Moscow State University and in the Joint Institute for Nuclear Research. The main goal of the authors is to bring readers into the interesting and intriguing problem of description of modern ex- perimental and observational data in the framework of ideas and methods elaborated until 1974 by the founders of the modern relativistic classical and quantum physics. The distinction of our approach from the stan- dard ones consists in using conformal symmetry: everywhere, from the horizon of the Universe to quarks, we use scale-invariant versions of mod- ern theories on the classical level with dimensionless coupling constants, breaking scale invariance only at the quantum level by normal ordering of products of field operators. The method of classification of novae data, obtained in the last fifteen years in cosmology and high–energy physics, essentially uses quantum theories and representations. From here the title of our book originated: “Principles of Quantum Universe”. Let us briefly present the content of the
