Horava-Witten M-Theory offers new ways in achieving the quark and lepton mass hierarchies not naturally available in supergravity unified models. In previous work, based on a torus fibered Calabi-Yau manifold with a del Pezzo base dP 7 ,a three generation SU(5)model with Wilson line breaking to the Standard Model was constructed. It was seen that if the additional 5-branes clustered near the di...

M ar 2 00 6 Existence of closed G 2 - structures on 7 - manifolds

In this note we propose a new way of constructing compact 7-manifolds with a closed G 2-structure. As a result we find a first example of a closed G 2-structure on S 3 × S 4. We also prove that any integral closed G 2-structure on a compact 7-manifold M 7 can be obtained by embedding M 7 to a universal space (W 3(80+8.C 3 8) , h). MSC: 53C10, 53C42 Key words: closed G 2-structures, submanifolds...

We identified a set of four rephasing invariant parameters of the CKM matrix. They are found to exhibit hierarchies in powers of λ 2 , from λ 2 to λ 8. It is shown that, at the present level of accuracy, only the first three parameters are needed to fit all available data on flavor physics.

We present the evidence that crossover, fluctuation phenomena and possible Anderson transition are the precursors of quark matter formation.
