IFT POSTEN - DATO

IFT POSTEN – 15.02.2008

Fra Instituttledelsen

I dag overleverer Dieter Röhrich og resten av utvalget sin rapport med råd om hvordan Norge bør forholde seg til kjernekraft basert på Thorium. Dette vil forhåpentligvis føre til en god og spennende debatt om både kjernekraft spesielt og energispørsmål generelt den nærmeste tiden, og forhåpentligvis også vil der bli et sterkt fokus på den grunnleggende kompetanseoppbygging som er nødvendig på universitetene i forhold til dette temaet!

I dag er det også liste over siste registrerte 4 ukers publikasjonsresultater fra IFT, to kjernefysikk og to romfysikkartikler samt åtte BABAR artikler. Fra nå av gjengis også sammendrag!

Jan Petter.

Bjorken expansion with gradual freeze out
Author(s): Magas VK, Csernai LP, Molnar E
Source: INTERNATIONAL JOURNAL OF MODERN PHYSICS E-NUCLEAR PHYSICS Volume: 16 Issue: 7--8 Pages: 1890-1895 Published: 2007

Abstract: The freeze out of the expanding systems, created in relativistic heavy ion collisions, will be discussed. We combine kinetic freeze out equations with Bjorken type system expansion into a unified model. Such a model is a more physical generalization of the earlier simplified non-expanding freeze out models. We shall see that the basic freeze out features, pointed out in the earlier works, are not smeared out by the expansion.

Three-body continuum energy correlations in Borromean halo nuclei. III. Short-range external fields
Author(s): Danilin BV, Vaagen JS, Rogde T, et al.
Source: PHYSICAL REVIEW C Volume: 76 Issue: 6 Article Number: 064612 Published: 2007

Abstract: Energy correlations in transitions from the bound state to the three-body continuum of Borromean halo nuclei are considered. A core+n+n three-body cluster model which reproduces the experimentally known properties of He-6 and Li-11 has been used to study the low-lying resonances and soft modes. An analysis of the correlated responses in He-6 shows that in the case of the narrow three-body 2(1)(+) resonance the transition energy correlations are the same as in the intrinsic correlated structure in 3 -> 3 scattering. They differ significantly for wide 2(2)(+),1(1)(+) resonances, and also for the soft dipole and monopole modes, where, due to the transition operators, the intertwining of the ground state and the three-body continuum plays a significant role.

A comparison of the probability distribution of observed substorm magnitude with that predicted by a minimal substorm model
Author(s): Morley SK, Freeman MP, Tanskanen EI
Source: ANNALES GEOPHYSICAE Volume: 25 Issue: 11 Pages: 2427-2437 Published: 2007

Abstract: We compare the probability distributions of substorm magnetic bay magnitudes from observations and a minimal substorm model. The observed distribution was derived previously and independently using the IL index from the IMAGE magnetometer network. The model distribution is derived from a synthetic AL index time series created using real solar wind data and a minimal substorm model, which was previously shown to reproduce observed substorm waiting times. There are two free parameters in the model which scale the contributions to AL from the directly-driven DP2 electrojet and loading-unloading DP1 electrojet, respectively. In a limited region of the 2-D parameter space of the model, the probability distribution of modelled substorm bay magnitudes is not significantly different to the observed distribution. The ranges of the two parameters giving acceptable (95% confidence level) agreement are consistent with expectations using results from other studies. The approximately linear relationship between the two free parameters over these ranges implies that the substorm magnitude simply scales linearly with the solar wind power input at the time of substorm onset.

Loss of relativistic electrons: Evidence for pitch angle scattering by electromagnetic ion cyclotron waves excited by unstable ring current protons
Author(s): Sandanger M, Soraas F, Aarsnes K, et al.
Source: JOURNAL OF GEOPHYSICAL RESEARCH-SPACE PHYSICS Volume: 112 Issue: A12 Article Number: A12213 Published: 2007

Abstract: During geomagnetic storms the flux of radiation belt electrons can increase, decrease, or stay constant, depending on the competition between acceleration and loss mechanisms. We focus on loss of relativistic electrons. We use low-altitude polar-orbiting spacecraft and analyze fluxes of tens to hundreds of keV protons and relativistic (> 1.5 MeV) electrons during a moderate geomagnetic storm, with a long-lasting recovery phase (4-5 d). Using data from four local times, we find that the loss of relativistic electrons is confined within the anisotropic proton zone and that a spatially limited loss of relativistic electrons is spatially collocated with increased loss of protons. The proton pitch angle distributions within these peaks are consistent with moderate to strong pitch angle scattering due to electromagnetic ion cyclotron (EMIC) waves. The loss of relativistic electrons collocated with protons is found at all four local times considered (0300, 0700, 1400, 1700 MLT). Since anisotropic proton distributions can under certain conditions generate EMIC waves, we find strong indications that the observed relativistic electrons are scattered into the atmospheric loss cone by EMIC waves. EMIC wave scattering is less efficient at high equatorial pitch angles but very efficient near the loss cone, thereby controlling the loss rate of relativistic electrons to the atmosphere. Our observations in and near the loss cone support theoretical work suggesting that EMIC waves can cause scattering loss to the atmosphere of relativistic electrons over the course of a geomagnetic storm.

Store kollaborasjoner:

Abstract: BaBar kollaborasjonen publiserer stadig nye data om elementærpartiklenes egenskaper. Sammen med Belle eksperimentet i Japan har vi et helt unikt datasett som muligjør et vell av studier både av B-mesoner, og også av andre partikler, slik som tau-leptonet, der disse kollaborasjonene nå også sitter på verdens største datamateriale.

Denne gangen rapporteres to studier av tau-leptonet (det tyngste ’elektronet’), og det er satt nye stringente grenser for brudd på leptontall, en bevaringslov i vår standardmodell, slik at de grensene gir føringer for hvordan fysikk utover standardmodellen må se ut.

Videre har BaBaR publisert nye resultater på CP-brytende prosesser i B-henfall, og produsert målinger og grenser for henfall i forskjellige kanaler. Alle disse målingene er med og bestemmer parametrene i CKM miksematrisen, som stadig får forbedret presisjon.
