A low α s and its consequences for unified model building
نویسندگان
چکیده
We review various ways of obtaining consistency between the idea of supersymmetric grand unification and an apparent low value of αs ∼ 0.112 indicated by several low energy experiments. We argue that to reconcile the low value of αs with the predictions of supersymmetric GUTs, we need to go beyond the standard minimal supersymmetric GUT scenario and invoke new physics either at 1011 − 1012 GeV, or at the GUT scale.

A Unified Approach for Design of Lp Polynomial Algorithms
By summarizing Khachiyan's algorithm and Karmarkar's algorithm forlinear program (LP) a unified methodology for the design of polynomial-time algorithms for LP is presented in this paper. A key concept is the so-called extended binary search (EBS) algorithm introduced by the author. It is used as a unified model to analyze the complexities of the existing modem LP algorithms and possibly, help ...
متن کاملPetrophysical and durability tests on sandstones for the evaluation of their quality as building stones using Analytical Hierarchy Process (AHP)
Due to their widespread availability, sandstones are commonly used as a natural stone for buildings, monuments and sculptures. In thecurrent study, nine sandstone samples from the Upper Red Formation (specified by the letters A, B, C, CG, S, S1, Sh, Tr and Min)were studied from a petrophysical point of view and their durability was evaluated. Then, their suitability as building stones wasassess...
متن کاملA comprehensive unified model of structural and reduced form type for defaultable fixed income bonds
The aim of this paper is to generalize the comprehensive structural model for defaultable fixed income bonds (considered in R. Agliardi, A comprehensive structural model for defaultable fixed-income bondsو Quant. Finance 11 (2011), no. 5, 749--762.) into a comprehensive unified model of structural and reduced form models. In our model the bond holders receive the deterministic co...
متن کاملDesigning and Validating the Service-Oriented University Model from the Standpoint of Higher Education Experts
Service orientation is a pivotal factor and a strategic direction for the university to keep with changes and perceptions of social needs. Accordingly, the main purpose of this study is to develop a model for the service-oriented university within the framework of service provision to the community. This research was conducted using a qualitative approach based on the grounded theory method. Th...
متن کاملSimulation of Smoke Emission from Fires in High-Rise Buildings Using the 3D Model Generated from 2-Dimensional Cadastral Data
Having a 3-Dimensional model of high-rise buildings can be used in disaster management such as fire cases to reduce casualties. The fundamental dilemma in 3D building modeling is the unavailability of suitable data sources. However, available cadastral 2D maps could be used as low-cost and attainable resources for 3D building modeling. Smoke will be a great threat to people's health during a f...
