Enhancement of lepton flavor violation in a model with bi-maximal mixing at the grand unification scale

We study phenomenological predictions in the scenario with the quasi-degenerate relation among neutrino Dirac masses, m_D1 simeq m_D2 < m_D3, assuming the bi-maximal mixing at the grand unification scale in supersymmetric standard models with right-handed neutrinos. A sufficient lepton number asymmetry can be produced for successful leptogenesis. The lepton flavor violating process mu to e gamma can be enhanced due to the Majorana phase, so that it can be detectable at forthcoming experiments. The processes tau to e gamma and tau to mu gamma are suppressed because of the structure of neutrino Dirac masses, and their branching ratios are smaller than that of mu to e gamma.Comment: 15 pages, 5 figure

Agent for preventing and ameliorating aging of skin

PROBLEM TO BE SOLVED: To obtain the subject new cosmetic by compounding a phosphorylated polysaccharide having humectant action and collagen-producing performance as an active component. SOLUTION: This cosmetic contains a compound of the formula (Glc is glucose residue; Gal is galactose residue; Rha is rhamnose residue; (m) is 0-3; (n) is 1,000-5,000) as an active component. The component of the formula can be produced by hydrolyzing actinase E of defatted milk, treating the defatted milk with ultrafiltration membrane, sterilizing the filtrate to obtain a culture medium, aseptically pipetting the sterilized medium into a jar fermenter, inoculating a precultured liquid, culturing at 20 deg.C and pH5.5 using NH3 water as a neutralizing agent, subjecting the cultured product to centrifugal separation after culture to recover the supernatant, adding an equal amount of CH3 OH, recovering the produced precipitate, dissolving the precipitate in 0.2N saline water, repeating the precipitation operation with CH3 OH, subjecting the treated precipitate to electrophoresis, recovering the component impregnated into the gel and purifying the recovered fraction by ion-exchange chromatography to obtain purified polysaccharide. It is necessary to compound a cosmetic with &gt;=0.001wt.% of the compound of the formula.</p

Phase effects from the general neutrino Yukawa matrix on lepton flavor violation

We examine contributions from Majorana phases to lepton flavor violating processes in the framework of the minimal supersymmetric standard model with heavy right-handed neutrinos. All phases in the complex neutrino Yukawa matrix are taken into account in our study. We find that in the scenario with universal soft-breaking terms sizable phase effects can appear on the lepton flavor violating processes such as $\mu \to e \gamma$, $\tau \to e \gamma$, and $\tau \to \mu \gamma$. In particular, the branching ratio of $\mu \to e \gamma$ can be considerably enhanced due to the Majorana phases, so that it can be much greater than that of $\tau \to \mu \gamma$.Comment: 14 pages, 4 eps figures, revtex

Scanning electron microscopy of myeloma cells

The surface structure of myeloma cells was examined by scanning electron microscopy. The cells were collected from the pleural effusion of a multiple myeloma patient and purified by Conray-Ficoll gradient sedimentation. The cell size ranged from 8 mu to 12 mu in diameter and the microvilli were from 0.8 mu to 1.2 mu in length. The surfaces of the majority of the observed myeloma cells were more villous than lymphocytes.</p

Search for Lepton Flavor Violation in the Higgs Boson Decay at a Linear Collider

We discuss possibility of direct search for lepton flavor violation (LFV) in Yukawa interaction by measuring the branching ratio for the decay of the lightest Higgs boson ($h^0$) into a $\tau$-$\mu$ pair at a linear collider. We study the significance of the signal process, $e^+e^- \to Z^\ast \to Z h^0 \to Z \tau^\pm \mu^\mp$, against the backgrounds such as $e^{+}e^{-} \to Z \tau^{+}\tau^{-} \to Z \tau^{\pm}\mu^{\mp}+$ missings. After taking appropriate kinematic cuts, the number of the background event is considerably reduced, so that the signal can be visible when the branching ratio of $h^0 \to \tau^\pm \mu^\mp$ is larger than about $10^{-4}$. In a Minimal Supersymmetric Standard Model scenario, the effective coupling of $h^0 \tau^\pm \mu^\mp$ can be generated at loop level due to the slepton mixing. When supersymmetric mass parameters are larger than TeV scales, the branching ratio can be as large as several times $10^{-4}$. Therefore, the signal can be marginally visible at a LC. In the general two Higgs doublet model, the possible maximal value for the branching ratio of $h^0 \to \tau^\pm \mu^\mp$ can reach to a few times $10^{-3}$ within the available experimental bound, so that we can obtain larger significance.Comment: 14 pages 3 figures, REVTEX4, version accepted for publication in Physics Letters
