Electric Dipole Moments in the Generic Supersymmetric Standard Model

The generic supersymmetric standard model is a model built from a supersymmetrized standard model field spectrum the gauge symmetries only. The popular minimal supersymmetric standard model differs from the generic version in having R-parity imposed by hand. We review an efficient formulation of the model and some of the recently obtained interesting phenomenological features, focusing on one-loop contributions to fermion electric dipole moments.Comment: 1+7 pages Revtex 3 figures incoporated; talk at NANP'0

In an Attempt to Introduce Long-range Interactions into Small-world Networks

Distinguishing the long-range bonds with the regular ones, the critical temperature of the spin-lattice Guassian model built on two typical Small-world Networks (SWNs) is studied. The results show much difference from the classical case, and thus may induce some more accurate discussion on the critical properties of the spin-lattice systems combined with the SWNs.Comment: 4 pages, 3 figures, 18 referenc

Difference in photosynthetic performance among three peach cultivars grown under low light conditions in greenhouses

The effects of low photosynthetic photon flux density (PPFD) on greenhouse grown peach trees (‘Qingfeng’: Prunus persica L. Batsch, ‘NJN76’: Prunus persica L. Batsch and ‘Maixiang’: P. persica var. nectarine) were investigated. Difference in photosynthesis rate (Pn) and stoma morphology among cultivars were studied. Furthermore, chlorophyll content, leaf thickness and photosynthesis enzyme activity were analyzed. Results showed that when PPFD was reduced to 80% of control, Pn decreased in all three cultivars. The reduced net photosynthesis rate was associated with decreased stoma density, stoma aperture and stoma conductance (Cs), as well as chlorophyll a (Chla) and b (Chlb) content in all cultivars; leaf mass per unit area (LMA) and thickness of upper and lower layers of leaf epidermis also declined. At 80% PPFD, the variation pattern of ribulose bisphosphate carboxylase (RuBPCase), Ca2+- adenosinetriphosphatase (Ca2+-ATPase) and Mg2+- adenosine triphosphatase (Mg2+-ATPase) activities, together with nicotinamide adenine dinucleotide phosphate (NADPH) content and photosynthetic O2 evolution rate among the three cultivars was the same as the pattern of LMA. Time course analysis showed that the net photosynthesis rate of ‘Maixiang’ was higher than that of the other two cultivars from 10:00 to 14:00. Though the parameters mentioned above decreased under shade in all the three cultivars, ‘Maixiang’ still had higher Pn than that of the other two cultivars. Our results indicated that ‘Maixiang’ is probably more suitable to grow in low PPFD than ‘Qingfeng’ and ‘NJN76’, especially in the early spring season in order to get higher market value.Key words: Prunus persica L., low light, photosynthesis, RuBPcase, Ca2+-ATPase, Mg2+-ATPase, NADPH content

A Detailed Analysis of One-loop Neutrino Masses from the Generic Supersymmetric Standard Model

In the generic supersymmetric standard model which had no global symmetry enforced by hand, lepton number violation is a natural consequence. Supersymmetry, hence, can be considered the source of experimentally demanded beyond standard model properties for the neutrinos. With an efficient formulation of the model, we perform a comprehensive detailed analysis of all one-loop contributions to neutrino masses.Comment: 27 pages Revtex, no figur
