Analysis of Running Coupling Constant Unification in String Theory

We use recently obtained 2-loop string coupling constants to analyze a class of string models based on orbifold compactification. Assuming weak coupling at the string scale and single-scale unification leads to restrictions on the spectrum of massive (between the string scale and the weak scale) matter supermultiplets and/or on the Kac-Moody algebra level.Comment: 12 page

One-loop Correction and the Dilaton Runaway Problem

We examine the one-loop vacuum structure of an effective theory of gaugino condensation coupled to the dilaton for string models in which the gauge coupling constant does not receive string threshold corrections. The new ingredients in our treatment are that we take into account the one-loop correction to the dilaton K\"ahler potential and we use a formulation which includes a chiral field $H$ corresponding to the gaugino bilinear. We find through explicit calculation that supersymmetry in the Yang-Mills sector is broken by gaugino condensation. The dilaton and $H$ field have masses on the order of the gaugino condensation scale independently of the dilaton VEV. Although the calculation performed here is at best a model of the full gaugino condensation dynamics, the result shows that the one-loop correction to the dilaton K\"ahler potential as well as the detailed dynamics at the gaugino condensation scale may play an important role in solving the dilaton runaway problem.Comment: 19 page

A New Interpretation of Quantum Physics Based On a New Definition of Consciousness

Although quantum physics has led to the most accurate predictions to date about the nature of matter and the universe, a metaphysical interpretation of its non-deterministic and subjective nature still remains an ongoing debate. In this work, we will review the nature of the debate and propose a new way to address the controversies about the non-deterministic and subjective nature of quantum physics. In our previous work, we have shown that everything is made of information, energy and matter. We propose to define spirit or soul as the content of information, spiritual heart as the receiver of information, and mind as the processor of information. In this paper, we show that the intrinsic uncertain and non-deterministic nature of quantum physics can be explained by the insights from these definitions. Information relates to the possibilities and potentialities of an object. Information is intrinsically uncertain and non-deterministic. Since quantum physics is the fundamental physics theory describing the information, energy and matter of everything, quantum physics has intrinsic an uncertain and non-deterministic nature. We further demonstrate that the process of quantum measurement can be interpreted as the role played by soul, spiritual heart and mind in the manifestation of physical phenomena. We conclude that our insight that everything is made of information, energy and matter and the definition of soul, spiritual heart and mind provides a simple metaphysical interpretation of quantum physics. They can help us understand and resolve the two controversies about quantum physics
