Neutrino Mass Matrix and Hierarchy

We build a model to describe neutrinos based on strict hierarchy, incorporating as much as possible, the latest known data, for $\Delta_{sol}$ and $\Delta_{atm}$, and for the mixing angles determined from neutrino oscillation experiments, including that from KamLAND. Since the hierarchy assumption is a statement about mass ratios, it lets us obtain all three neutrino masses. We obtain a mass matrix, $M_\nu$ and a mixing matrix, $U$, where both $M_\nu$ and $U$ are given in terms of powers of $\Lambda$, the analog of the Cabibbo angle $\lambda$ in the Wolfenstein representation, and two parameters, $\rho$ and $\kappa$, each of order one. The expansion parameter, $\Lambda$, is defined by $\Lambda^2 = m_2/m_3 = \surd (\Delta_{sol}/\Delta_{atm}) \approx$ 0.16, and $\rho$ expresses our ignorance of the lightest neutrino mass $m_1, (m_1 = \rho \Lambda^4 m_3$), while $\kappa$ scales $s_{13}$ to the experimental upper limit, $s_{13} = \kappa \Lambda^2 \approx 0.16 \kappa$. These matrices are similar in structure to those for the quark and lepton families, but with $\Lambda$ about 1.6 times larger than the $\lambda$ for the quarks and charged leptons. The upper limit for the effective neutrino mass in double $\beta$-decay experiments is $4 \times 10^{-3} eV$ if $s_{13} = 0$ and $6 \times 10^{-3} eV$ if $s_{13}$ is maximal. The model, which is fairly unique, given the hierarchy assumption and the data, is compared to supersymmetric extension and texture zero models of mass generation.Comment: 8 pages, LaTex, This paper updates an earlier version by incorporating KamLAND dat

Crossing-symmetric rising Regge trajectories

Corrections due to the exchange of the resonances lying on the leading crossed-channel Regge trajectory are calculated for a linearly rising Regge trajectory in a single-channel, single-trajectory model. The corrections are small, and the equations force no restriction on the slope or intercept of the trajectory. The integral equations for the Regge parameters are derived, and detailed numerical results for the ρ trajectory are given. A method for determining the slope of the trajectory is proposed

Neutrino oscillations in matter of varying density

We consider two-family neutrino oscillations in a medium of continuously-varying density as a limit of the process in a series of constant-density layers. We construct analytic expressions for the conversion amplitude at high energies within a medium with a density profile that is piecewise linear. We compare some cases to understand the type of effects that depend on the order of the material traversed by a neutrino beam.Comment: 10 page

Complex Regge poles in the cut j plane: Pion-nucleon charge-exchange scattering

The structure of the pole-cut combination in πN charge-exchange scattering for t<~0 is represented by a pair of complex poles. Excellent fits to the πN charge-exchange differential cross section, polarization, and total cross-section difference σt(π-p)-σt(π+p) are obtained for the two examples considered, Imα=gsqrt[-t] and Imα=g. The phases of the residues are allowed to vary and a zero in ImA′(-) (the "crossover" zero) is obtained

On Neutrinos and Fermionic Mass Patterns

Recent data on neutrino mass differences are consistent with a hierarchical neutrino mass structure strikingly similar to what is observed for the other fermionic masses.Comment: 8pages, 2figure

On neutrino masses and leptonic mixing

Using recent data on neutrino oscillations, we argue that a hierarchical solution for neutrino masses in a three-family context is possible, and that the masses of the tau and mu neutrinos are very nearly determined within that possibility. We also examine the predictions of a model that determines neutrino and charged lepton mass matrices as well as its consistency with data.Comment: 13 pages, 6 figures, technical change to pdf, figures include

Neutrino propagation in matter and CP violation

We point out that the dependence on the order of the matter through which neutrinos pass can provide a window into CP violation in the neutrino sector. This allows for study of CP in the neutrino sector without the necessity of making a comparison between the behavior of neutrinos and that of antineutrinos.Comment: 10 pp, including three figures; added references, fixed typo

Alu-repeat–induced deletions within the NCF2 gene causing p67- phox –deficient chronic granulomatous disease (CGD)

Mutations that impair expression or function of the components of the phagocyte NADPH oxidase complex cause chronic granulomatous disease (CGD), which is associated with life-threatening infections and dysregulated granulomatous inflammation. In five CGD patients from four consanguineous families of two different ethnic backgrounds, we found similar genomic homozygous deletions of 1,380 bp comprising exon 5 of NCF2 , which could be traced to Alu-mediated recombination events. cDNA sequencing showed in-frame deletions of phase zero exon 5, which encodes one of the tandem repeat motifs in the tetratricopeptide (TPR4) domain of p67- phox . The resulting shortened protein (p67Δ5) had a 10-fold reduced intracellular half-life and was unable to form a functional NADPH oxidase complex. No dominant negative inhibition of oxidase activity by p67Δ5 was observed. We conclude that Alu-induced deletion of the TPR4 domain of p67- phox leads to loss of function and accelerated degradation of the protein, and thus represents a new mechanism causing p67- phox –deficient CGD.
