  1. 134. Precision measurements of fundamental properties of atomic particles
    Prof. Klaus Blaum (Max Planck Institut für Kernphysik)
    18/10/2016, 11:00
    Precision measurements of fundamental constants
    Oral
    This contribution will provide an overview on recent applications of precision measurements with cooled and stored ions in Penning traps. One the one hand, precision Penning-trap mass measurements provide indispensable information for atomic, nuclear and neutrino physics as well as for testing fundamental symmetries [1,2]. On the other hand, in-trap measurements of the bound-electron g-factor...

  2. 176. Fundamental weak interaction studies with electron beams
    Prof. Frank Maas (Helmholtz Institute Mainz, GSI and Mainz University)

    Low energy precision tests of the Standard Model
    Oral
    Sensitive tests of the standard model are possible through high precision determinations of the weak mixing angle using parity violation electron scattering. The precision which can be reached at very low Q^2 is comparable with the measurements obtained from LEP which are at present still the most precise determinations. Mass scales of new interactions upt to 50 TeV are tested. The...

  3. 139. Lepton flavour violation in RS models with a brane- or nearly brane-localized Higgs
    Dr Paul Moch (Universität Siegen)
    18/10/2016, 12:00
    Low energy precision tests of the Standard Model
    Oral
    We perform a comprehensive study of charged lepton flavour violation in Randall-Sundrum (RS) models in a fully 5D quantum-field-theoretical framework. We consider the RS model with minimal field content and a ``custodially protected'' extension as well as three implementations of the IR-brane localized Higgs field, including the non-decoupling effect of the KK excitations of a...

  4. 198. Neutron Lifetime Measurement at J-PARC/MLF/BL05
    Tatsuhiko Tomita (Kyushu University)
    18/10/2016, 12:20
    Fundamental physics and precision experiments with muons, pions, neutrons, antiprotons, and other particles
    Oral
    The neutron lifetime (880.3 ± 1.1 [sec] [Particle Data Group]) is one of the most important parameters for the Big Bang Nucleosynthesis, which predicts nucleosynthesis in the early universe. So far it has been measured by two different methods, penning trap and UCN bottle, and they got recent value 888.0 ± 2.1 [sec] and 879.6 ± 0.8 [sec] respectively. Although both methods decide the lifetime...
