We study linear torsional Alfvén waves in a magnetic flux tube with an arbitrary cross-section. assume that the equilibrium field is propagating z-direction Cartesian coordinates x,y, and z. The cross-section bounded by smooth closed curve. Both plasma are homogeneous outside this magnitude function of x y, while density product two functions: one dependent on z other y. As result, speed also e...

The non-relativistic cross section from Rayleigh scattering by hydrogen atoms in the ground state is calculated over a wide range of photon energies ($< 0.8$ keV). Evaluations are performed terms real and imaginary components atomic polarizability. sum intermediate states that characterizes this second-order radiative process using exact analytic expressions for oscillator strengths bound conti...

Accurate measurements of particles masses, couplings and widths are possible by measuring production cross sections near threshold. We discuss the prospects for performing such measurements at a high luminosity muon collider.

Results on the cross section measurement of Z boson pair–production at LEP 1,2 are presented. The more general case of neutral–current four–fermion production and the particular case of ZZ events enriched in b quarks are also discussed. All the results agree with the Standard Model predictions.

We demonstrate the use of high-speed, multiphoton absorption polymerization (MAP) for the fabrication of large-area microfluidic master structures. High-speed fabrication in SU8 without laser-induced damage is made possible by the use of a novel photoacid generator with a high two-photon-absorption cross-section. Master structures fabricated with MAP can be used to produce polydimethylsiloxane ...

Abstract We investigate fixed energy scattering from conical potentials having an irregular cross-section. The incident wave can be arbitrary non-trivial Herglotz wave. show that a large number of such local scatterers scatter all waves, meaning the far-field will always non-zero. In essence there are no waves for which these would seem transparent at any given energy. more specifically is coll...

These supplementary notes are provided in an educational spirit. Section 2 shows how the cross-product formula for computing columns of the Jacobian emerges from direct calculus. Section 5 extends to arbitrary Euler angles. Our work is not limited to homogeneous coordinates or Euler angles. However, these representations are well known and chosen merely to present to a wider audience. In fact o...

We present an updated analysis of astrophysical solutions, two-flavor MSW solutions, and vacuum oscillation solutions to the solar neutrino anomaly. The recent results of each of the five solar neutrino experiments are incorporated, including both the zenith angle (day-night) and spectral information from the Kamiokande experiment, and the preliminary SuperKamiokande results. New theoretical de...

Quantitative predictions for the energy and A dependence of the nuclear photoabsorption cross section and inelastic electron-nucleus scattering are given. In general each nucleon does not contribute equally to the total photon-nucleus cross section when coherent contributions of photoproduced hadrons are taken into account. At low energies (E Y N 1 BeV) the cross sections are proportional to nu...
