  2010 AUG 31 - (VerticalNews.com) -- According to recent research published in the International Journal of Modern Physics a, "We present a complete and minimal catalogue of MSSM gauge invariant monomials. That is, the catalogue of Gherghetta, Kolda and Martin is elaborated to include generational structure for all monomials."

  "Any gauge invariant operator can be built as a linear combination of elements of the catalogue lifted to nonnegative integar powers. And the removal of any one of the monomials would deprive the catalogue of this feature. It contains 712 monomials, plus 3 generations of right-handed neutrinos if one extends the model to the vMSSM," wrote A. Basboll and colleagues, University of Sussex ...read more

  2010 AUG 31 - (VerticalNews.com) -- According to a study from Japan, "A dynamical mechanism for symmetry breaking is investigated under the circumstances with the finite curvature, finite size and nontrivial topology."

  "A four- and eight-fermion interaction model is considered as a prototype model which induces symmetry breaking at GUT era," wrote M. Hayashi and colleagues, Hiroshima University.

  The researchers concluded: "Evaluating the effective potential in the leading order of the 1/N-expansion by using the dimensional regularization, we explicitly calculate the phase boundary which divides the symmetric and the broken phase in a weakly curved space-time and a. at space-time with nontrivial topology, RD-1 circle times S-1. ...read more

  2010 AUG 31 - (VerticalNews.com) -- According to recent research from the United States, "Ever since its discovery the notion of Berry phase has permeated through all branches of physics. Over the past three decades it was gradually realized that the Berry phase of the electronic wave function can have a profound effect on material properties and is responsible for a spectrum of phenomena, such as polarization, orbital magnetism, various (quantum, anomalous, or spin) Hall effects, and quantum charge pumping. ...read more
