Limits on ν µ → ν τ oscillations and tau neutrino magnetic moment from neutrino-electron scattering Abstract If the tau neutrino has large magnetic moment it might be effectively used to search for ν µ −ν τ neutrino oscillations in neutrino-electron scattering in beam dump experiments. Using the present experimental limits on the magnetic moments of tau and muon neutrinos, limit on the probabil...

It is shown that the rare decays Z → ν ¯ νγ and Z → ν ¯ νγγ are useful to put model-independent bounds on neutrino-one-photon and neutrino-two-photon interactions. The results are then used to constrain the τ neutrino magnetic moment µ ντ and the double radiative decay ν j → ν i γγ. It is found that the decay Z → ν ¯ νγ gives a more stringent bound on µ ντ than that obtained from Z → ν ¯ νγγ; t...

As an application of the method used to obtain the result above, we will obtain the consistency of b = ω1 < s = κ where b is the bounding number, s is the splitting number and κ is an arbitrary regular cardinal. Suppose ν ≥ δ. Begin with a model of GCH and adjoin δ-many Cohen reals 〈rα : α ∈ δ〉 followed by ν-many Random reals 〈sξ : ξ ∈ ν〉. That is, if Vδ is the model obtained after the first δ ...

Let ν be a finite Borel measure on [0, 1]. Consider the L-spectrum of ν: τν(q) = lim infn→∞−n logb P Q∈Gn ν(Q) q (q ≥ 0), where Gn is the set of b-adic cubes of generation n (b integer ≥ 2). Let qτ = inf{q : τν(q) = 0} and Hτ = τ ′ ν(q τ ). When ν is a mono-dimensional continuous measure of information dimension D, (qτ , Hτ ) = (1, D). When ν is purely discontinuous, its information dimension i...

Let u be a solution to the Navier-Stokes equations in the unit disk with no-slip boundary conditions and viscosity ν > 0, and let u be a smooth solution to the Euler equations. We say that the vanishing viscosity limit holds on [0, T ] if u converges to u in L∞([0, T ];L). We show that a necessary and sufficient condition for the vanishing viscosity limit to hold is the vanishing with the visco...

We investigate the rare decay processes of the K mesons, K L,S → π 0 ν ¯ ν and K + → π + ν ¯ ν in LR model with lepton family number being well conserved. In these processes, scalar operators (¯ sd)(¯ ν τ ν τ), which are derived from box diagram in LR model, play an important role due to an enhancement factor M K /m s in the matrix element < π|¯ sd|K >. It is emphasized that the K L decay proce...

Received Day Month Year Revised Day Month Year We study a nonequilibrium model with up-down symmetry and a noise parameter q known as majority-vote model of M.J. Oliveira 1992 on opinion-dependent network or Stauffer-Hohnisch-Pittnauer networks. By Monte Carlo simulations and finite-size scaling relations the critical exponents β/ν, γ/ν, and 1/ν and points qc and U * are obtained. After extensi...

We present a nearly optimal (O(ν min(ν, n)n log n) time and O(n) space) algorithm that constructs a shortest path map with n isothetic roads of speed ν under the L1 metric. The algorithm uses the continuous Dijkstra method and its efficiency is based on a new geometric insight; the minimum in-degree of any nearest neighbor graph for points with roads of speed ν is Θ(ν min(ν, n)), which is first...

Dimensional continuation is employed to compute the energy loss rate for a non-relativistic particle moving through a highly ionized plasma. No restriction is made on the charge, mass, or speed of this particle, but it is assumed that the plasma is not strongly coupled in that the dimensionless plasma coupling parameter g = e 2 κ D /4πT is small, where κ D is the Debye wave number. To leading o...
