We identify the untwisted moduli of heterotic orbifold compactifications for the case, when the gauge twist is realized by a rotation. The Wilson lines are found to have both continuous and discrete parts. For the case of the standard Z3 orbifold we classify all possibilities of breaking the gauge group E(6)⊗SU(3) by nine of the eighteen Wilson moduli and by additional discrete Wilson lines. Ne...

I am honored to be the E. B. Wilson Award recipient for 2015. As we know, it was E. B. Wilson who popularized the concept of a "stem cell" in his book The Cell in Development and Inheritance (1896, London: Macmillan & Co.). Given that stem cell research is my field and that E. B. Wilson is so revered within the cell biology community, I am a bit humbled by how long it took me to truly grasp his...

Polarized forward–backward asymmetries in the Bs → l+l−γ decay are calculated using the most general, model independent form of the effective Hamiltonian, including all possible forms of interactions. The dependencies of the asymmetries on new Wilson coefficients are investigated. The detectability of the asymmetries at LHC is discussed.

Using the most general, model independent effective Hamiltonian, the branching ratio of the B → Kll decay, when K meson is longitudinally or transversally polarized, is presented. The dependence of the branching ratio on the new Wilson coefficients, when K meson is polarized, is studied. It is observed that the branching ratio is very sensitive to the vector and tensor type interactions, which ...

Computer systems are fully capable of providing customized interfaces for users. Every time we log on to an ecommerce website we have used before, the interface changes in order to fit our most probable interests. Some sophisticated vehicles adjust the seat position, rearview mirror orientation and other parameters to match the preferences of the drivers when they enter the car -provided that t...
