We investigate gauge coupling unification in higher dimensional GUT models with split supersymmetry. We focus on 5d and 6d orbifold GUTs, which permit a simple solution to several problems of 4D GUTs as well as control over GUT scale threshold corrections. In orbifold GUTs, calculable threshold corrections can raise or lower the prediction for αs(MZ) in a way that depends on the location of Hig...

In previous studies we detected lower species richness and lower Hg sensitivity of the bacteria present in egested guts of Porcellio scaber (Crustacea, Isopoda) from chronically Hg polluted than from unpolluted environment. Basis for such results were further investigated by sequencing of 16S rRNA genes of mercury-resistant (Hgr) isolates and clone libraries. We observed up to 385 times higher ...

Gauge and Yukawa (for the third family) coupling unification seem to be the best predictions of the grand-unified theories (GUTs). In supersymmetric GUTs, one also expects that the sparticle masses unify at the GUT scale (for sparticles embedded in the same GUT multiplet). I show under what circumstances GUTs do not lead to sparticle mass unification. In particular, I give examples of SU(5) and...

Abstract We review proton decay in the SUSY SU(5) GUTs assuming mini-split breaking model. In model, squark and slepton masses are O(10(2 − 3)) TeV while gaugino O(1) TeV. As result, even minimal GUT is still viable present motivation of model discuss future prospects searches GUTs.

Maybe the biggest puzzle in grand unified theories (GUTs) is apparent large splitting of doublet and triplet Higgs masses. We suggest a novel mechanism to solve this puzzle, which relies on clockwork generate hierarchies from order-one numbers. The tension between gauge coupling unification proton lifetime minimal SU(5) GUTs also removed scenario, theory remains perturbative until Planck scale....

We review the theoretical and experimental status of minimal grand unified theories (GUTS), contrasting the failure of minimal non-supersymmetric SU(5) with the success of the minimal supersymmetric SU(5) and minimal supersymmetric Flipped SU(5)× U(1) models. We show that a reasonable value for the universal soft supersymmetry-breaking gaugino mass, 45GeV < m1/2 < 1TeV, and a 1−σ range of the o...

Selenium is both an essential and a toxic trace element, and the range of concentrations between the two is extremely narrow. Although tellurium is not essential and is only rarely found in the environment, it is considered to be extremely toxic. Several hypotheses have been proposed to account for the toxic effects of selenite and tellurite. However, these potential mechanisms have yet to be f...

This study was carried out to determine the palmitoylethanolamide (PEA) and arachidonoylethanolamide (AEA) or anandamide contents in selected fish wastes, treating wastes with highest PEA AEA different concentration of monoethanolamine (MEA) solution, incubation temperature time, as well ratio MEA solution waste further increase its contents.&#x0D; Based on results preliminary experiment, a fra...
