The CKM Phase in Heterotic Orbifold Models
We consider properties of the CKM phase in the heterotic orbifold models. We find that at the renormalizable level the CKM phase vanishes identically for the prime orbifolds, whereas it can be non-zero for some non-prime orbifolds. In particular, we study in detail the Z6-I orbifold which allows for a non-trivial CKM phase and analyze the modular properties of the corresponding Jarlskog invaria...
متن کاملMultistage models for carcinogenesis.
The multistage model is tested on several human and animal data sets. It fits in some cases but not in others. With human lung cancer data, there is a drop in risk for ex-smokers quite different from the predictions of the model. The results are not conclusive but are compatible with the view that the multistage model provides a family of curves that often fit cancer incidence data, but may not...
متن کاملMultistage models of carcinogenesis.
The simple multistage model of carcinogenesis is outlined. It provides a satisfactory explanation of the power law for the age incidence of many forms of epithelial carcinoma, for the effects in human populations of changing exposures to supposed carcinogenic agents, and for many of the observed effects of applied carcinogens in animal experiments. In particular, the evidence on the effects of ...
متن کاملCKM Matrix in Models with Dynamical Mass Generation
We investigate the quark flavor mixing in the charged current sector in models of the electroweak symmetry breaking (EWSB) with dynamical mass generation. Using the Lehmann-Symanzik-Zimmermann (LSZ) reduction formula, we calculate the Cabibbo-Kobayashi-Maskawa (CKM) matrix out of the quark self-energies with an arbitrary momentum dependence. We show that depending on the particular model of the...
متن کاملCarcinogenesis in transgenic mouse models.
Background: Safe and effective weight control strategies are needed to stem the current obesity epidemic. The objective of this one-year study was to document and compare the macronutrient and micronutrient levels in the foods chosen by women following two different weight reduction interventions. Methods: Ninety-six generally healthy overweight or obese women (ages 25–50 years; BMI 25– 35 kg/m...
