We study the muon anomalous magnetic moment (g − 2) μ in the context of the reduced minimal 3-3-1 model recently proposed in the literature. In particular, its spectrum contains a doubly charged scalar (H ±± ) and gauge boson (U ±± ), new singly charged vectors (V ± ) and a Z boson, each of which might give a sizeable contribution to the (g − 2) μ . We compute the 1-loop contributions from all these new particles to the (g − 2) μ . We conclude that the doubly charged vector boson provides the dominant contribution, and by comparing our results with the experimental constraints we derive an expected value for the scale of SU(3) L ⊗ U (1) N symmetry breaking v χ ∼ 2 TeV. We also note that, if the discrepancy in the anomalous moment is resolved in the future without this model then the constraints will tighten to requiring v χ 3.7 TeV with current precision, and they will entirely rule out the model if the expected precision is achieved by the future experiment at Fermilab.

“…The extra matter on other branes, therefore, behaves exactly as Dark Matter (taking into account present bounds on direct and indirect Dark Matter searches, from which only very tight upper bounds on nongravitational cross-sections of Dark Matter particles with SM ones can be derived, see for example Ref. [24] for a recent review).…”

We consider a five-dimensional model with geometry M = M 4 × S 1 , with compactification radius R. The Standard Model particles are localized on a brane located at y = 0, with identical branes localized at different points in the extra dimension. Objects located on our brane can orbit around objects located on a brane at a distance d = y/R, with an orbit and a period significantly different from the standard Newtonian ones. We study the kinematical properties of the orbits, finding that it is possible to distinguish one motion from the other in a large region of the initial conditions parameter space. This is a warm-up to study if a SMlike mass distribution on one (or more) distant brane(s) may represent a possible dark matter candidate. After using the same technique to the study of orbits of objects lying on the same brane (d = 0), we apply this method to the detection of generic deviations from the inverse-square Newton law. We propose a possible experimental setup to look for departures from Newtonian motion in the micro-world, finding that an order of magnitude improvement on present bounds can be attained at the 95% CL under reasonable assumptions.

“…Strain and cultivation : The alternarlactam‐producing fungus, identified by Dr. Y. C. Song as Alternaria sp. HG1 according to its macro‐ and micro‐graphic morphological characteristics,27 was isolated from inside the fresh Carex aridula leaves collected in November 2001 from the suburb of Nanjing, China. The fresh mycelia grown on PDA plates were incubated into 1000 mL flasks preloaded with each 400 mL potato dextrose broth followed by shaking at 140 rpm at 25 °C for 5 d. After that, the liquid culture (10 mL) was transferred into each of 400 bottles containing millet medium,28 before hatched quietly at 25 °C for 30 d. At the end of the solid‐substrate fermentation, a total of 40 L fermented material was harvested, dehydrated, and then pulverized into dry powder (ca.…”

(-)-Alternarlactam [(-)-1], a new promising cytotoxin against two human cancer cell lines, was isolated from an endophyte culture and synthesized (along with (+)-1) from readily available starting materials. The absolute configuration, chirality-activity relevance and self-aggregation of (-)-1 were assigned by a combination of synthetic, spectroscopic and computational approaches. The full characterization of the new fungal cytotoxin may provide valuable information in the discovery of new antitumor agents.
