A wave equation for free fermions is proposed based on the structure of dual theory bosons. Its formal properties preserve role played by Virasoro algebra. Additional Ward-like identities, compatible with equation, are shown to exist. solutions lie linear trajectories. In particular, parent be doubly degenerate, but these different sheets cut $j$ plane.

We generalize the classical action-at-a-distance theory between point particles to include one-dimensionally extended objects (strings) in space-time. build parametrization-invariant couplings which lead equations of motion for strings each others' influence. The direct coupling area elements world sheets is considered detail, from we define an antisymmetric adjunct field. find that, a given interaction, nature forces depends on type involved, that is, open- vs closed-ended. Our can be...

This paper is a review of the present status neutrino mass physics, which grew out an APS sponsored study neutrinos in 2004. After discussion knowledge masses and mixing some popular ways to probe new physics implied by recent data, it summarizes what can be learned about interactions as well nature beyond Standard Model from various proposed experiments. The intriguing possibility that may at heart our understanding long standing puzzle cosmology, i.e. origin matter–antimatter asymmetry...
Three problems in hypothetical unified theories of electromagnetic, weak, and strong interactions are discussed here. First, the problem embedding color any simple gauge group is solved, a complete classification where fermion restricted to ${1}^{c}$, ${3}^{c}$, ${\overline{3}}^{c}$ $\mathrm{S}{\mathrm{U}}_{3}^{c}$ given. Generalizations also indicated. Second, an unbroken ${\mathrm{U}}_{1}$ generated by electric charge embedded into each above assignments analyzed. Third, general...
In this paper we present a comprehensive analysis of the running all couplings standard model to two loops, including threshold effects. Our purpose is twofold---to determine what these parameters may indicate for physics and provide template study its extensions up Planck mass.
Members of the IS3 family insertion sequences are found in a wide range bacteria. At least 10 members this carry two major open reading frames: small upstream frame (0 phase), and longer downstream -1 phase. The shows significant similarity at amino acid level. A highly conserved region also exhibits notable with integrase (endonuclease) domain retroviruses. Although overall transposition mechanism sequence retroviral elements is certainly different, groups may share additional common...
We present a supersymmetric standard model with three gauged Abelian symmetries of type commonly found in superstrings. One is anomalous; the other two are ${E}_{6}$ family symmetries. It has vacuum which only these broken by stringy effects. reproduces all observed quark and charged lepton Yukawa hierarchies value Weinberg angle. predicts massive neutrinos, mixing that can explain both small angle MSW effect atmospheric neutrino anomaly. The Cabibbo expressed terms gauge couplings at...

We run all the couplings of minimal supersymmetric (SUSY) extension standard model, taking account Yukawa sector. After identifying scale at which gauge unify, we place bounds on top-quark mass by requiring equality bottom-quark and \ensuremath{\tau} that scale. For ${\mathit{M}}_{\mathrm{SUSY}}$=1 TeV, ${\mathit{M}}_{\mathit{b}}$=4.6 GeV, find 139\ensuremath{\le}${\mathit{M}}_{\mathit{t}}$\ensuremath{\le}194 remarkably satisfy \ensuremath{\rho}-parameter bound. Furthermore, using SUSY...
In this paper we summarize the minimal supersymmetric standard model as well renormalization group equations of its parameters. We proceed to examine feasability when breaking supersymmetry is parametrized by soft terms suggested supergravity theories. such models, electroweak symmetry exact at tree level and broken spontaneously one loop order. make additional assumption that GUT-inspired relation $m_b=m_\tau$ be valid scale where gauge coupling constants unify, which constrains value top...
The large neutrino mixing angles have generated interest in finite subgroups of SU(3), as clues towards understanding the flavor structure standard model. In this work, we study mathematical simplest non-Abelian subgroup, Δ(3n2). Using simple techniques, derive its conjugacy classes and character table, build irreducible representations, their Kronecker products, invariants.
