A kind of prediction from superstring model building
نویسنده
چکیده
Assuming that the Standard Model of particle physics arises from the E8×E8 Heterotic String Theory, we try to solve the discrepancy between the unification scale predicted by this theory (≈ gGUT × 5.27 · 1017 GeV) and the value deduced from LEP experiments (≈ 2 · 1016 GeV). A crucial ingredient in our solution is the presence at low energies of three generations of supersymmetric Higgses and vector-like colour triplets. As a by-product our analysis gives rise to a strategy which might be useful when constructing realistic models.

Application of Genetic Programming to Modeling and Prediction of Activity Coefficient Ratio of Electrolytes in Aqueous Electrolyte Solution Containing Amino Acids
Genetic programming (GP) is one of the computer algorithms in the family of evolutionary-computational methods, which have been shown to provide reliable solutions to complex optimization problems. The genetic programming under discussion in this work relies on tree-like building blocks, and thus supports process modeling with varying structure. In this paper the systems containing amino ac...

Model building is one of the most important characteristics of human beings. According to a classification, there are three kinds of models. The first type are omdels which are unique to every individual person and every body has his own models. Another kind of models are those which are general. Theories arise from this kind of models. The third kind are modols for model building and deals wit...

We review the possibility that the Supersymmetric Standard Model arises from orbifold constructions of the E8×E8 Heterotic Superstring, and the phenomenological properties that such a model should have. In particular, trying to solve the discrepancy between the unification scale predicted by the Heterotic Superstring (≈ gGUT × 5.27 · 10 17 GeV) and the value deduced from LEP experiments (≈ 2 · ...
متن کاملPrediction of ultimate strength of shale using artificial neural network
A rock failure criterion is very important for prediction of the ultimate strength in rock mechanics and geotechnics; it is determined for rock mechanics studies in mining, civil, and oil wellborn drilling operations. Also shales are among the most difficult to treat formations. Therefore, in this research work, using the artificial neural network (ANN), a model was built to predict the ultimat...
