Abstract The present research proceeding aims at investigating/exploring/sharpening the phenomenological consequences of string theory and holography in particle physics and cosmology. We rely on and elaborate on the recently proposed framework whereby four-dimensional quantum field theories describe all interactions in Nature, and gravity is an emergent and not a fundamental force. New gauge fields, axions, and fermions, which can play the role of right-handed neutrinos, can also emerge in this framework. Preprint: UWThPh 2021-8

General Relativity (GR) and the Standard Model (SM) of particle physics are two enormously successful frameworks for our understanding the fundamental laws of nature. However, these theoretical schemes are widely disconnected, logically independent and unrelated in scope. Yet, GR and SM at some point must intersect, producing claims about phenomena that should be reconciled. Be it as it may, both schemes share a common basic ground: symmetry under local Lorentz transformations. Here, we will focus on the consequences of assuming this feature from the beginning to combine geometry, matter fields and gauge interactions. We give a rough description of how this could be instrumental for the construction of a unified scheme of gravitation and particle physics.

The three-flavor neutrino oscillation paradigm is well established in particle physics thanks to the crucial contribution of accelerator neutrino beam experiments. In this paper, we review the most important contributions of these experiments to the physics of massive neutrinos after the discovery of θ 13 and future perspectives in such a lively field of research. Special emphasis is given to the technical challenges of high power beams and the oscillation results of T2K, OPERA, ICARUS, and NO ν A. We discuss in detail the role of accelerator neutrino experiments in the precision era of neutrino physics in view of DUNE and Hyper-Kamiokande, the program of systematic uncertainty reduction and the development of new beam facilities.

The Standard Model

The existence of magnetic monopoles is predicted by many theories of particle physics beyond the standard model. However, in spite of extensive searches, there is no experimental or observational sign of them. I review the role of magnetic monopoles in quantum field theory and discuss their implications for particle physics and cosmology. I also highlight their differences and similarities with monopoles found in frustrated magnetic systems.

The known weakness of Gravity in particle physics is a delusion caused by underestimation of the role of spin. Spin of elementary particles is extremely high and exceeds mass on 20-22 orders (in unit’s c = G = m = k = 1). The caused by spinning gravity framedragging distorts space much stronger than mass, that shifts the usual effective scale of gravitational interaction from Planck to Compton distances. We show that compatibility between gravity and quantum theory can be achieved without modifications of the Einstein equations, by using a model of super-bag a no perturbative particle like solution to supersymmetric system of the Landau-Ginzburg (Higgs) field equations. Super-bag generates a free from gravity Compton zone for quantum theory. Shape of the bag is defined unambiguously by spinning Kerr-Newman solution. For parameters of an electron (charge e, spin J, and mass m) super-bag forms a thin superconducting disk of Compton radius coupled with circular string along its perimeter. The supersymmetric LG (Higgs) model is naturally upgraded to Wess-Zumino super-QED model, forming a bridge to perturbative formalism of conventional QED.

Science Part

The first major theme of the book is introduced. This is that science does not present a ladder or tower of explanation, but a network of mutually interacting and informing ideas. The digital computer is invoked to introduce the concept of low-level and high-level language. The role of symmetry and symmetry principles in physics is discussed at length. It is argued, in agreement with Anderson, that symmetry is central to fundamental physics, but, more importantly, it is shown that what symmetry offers is a subtle constraining influence that is not the same as cause and effect, but is nevertheless central to the concept of explanation and understanding. It is argued that the laws of thermodynamics and the laws of particle physics are in a relationship of mutual consistency with neither able to render the other superfluous. Numerous examples are invoked.

As the pool of fundamental data available to astronomers continues to increase, the question of how best to promote the necessary cross-discipline interaction becomes increasingly important. Commission 14 has traditionally played an important role in this activity, by publishing triennial reports in the IAU Proceedings, as well as by responding to more specific requests for data. We are fortunate in having the support for these activities of some energetic Working-Groups and Chairmen, whos contributions to the present report are very gratefully acknowledged. With the expansion of available data it is appropriate that these reports take on more and more the form of references to review articles and other more specific data bases. The question of whether the field of activity of the Commission should be enlarged was discussed at Patras and will be reviewed again at the Delhi meeting. One possibility is to include nuclear processes and fundamental particle physics. On the other hand a rationale for limiting the scope of our activities might be the direct application to astronomical observations. Astronomical theorists are usually better placed to access the fundamental data themselves. The interaction between fundamental physics and astronomy will in general take two forms. There is the essential service role of making data available in a usable form. However, we should surely aim to stimulate the other very profitable mode, in which the two disciplines are brought together to form real scientific collaborations, in order to research the problems of astronomy.
