Frequency spectra of cosmic ray air shower radio emission measured with LOPES
A. Nigl
AIMS: We wish to study the spectral dependence of the radio emission from cosmic-ray air showers around 100 PeV (1017 eV). METHODS: We observe short radio pulses in a broad frequen…
Direction identification in radio images of cosmic-ray air showers detected with LOPES and KASCADE
A. Nigl
AIMS: We want to understand the emission mechanism of radio emission from air showers to determine the origin of high-energy cosmic rays. Therefore, we study the geometry of the ai…
Neutrino-Mass Hierarchies and Non-linear Representation of Lepton-Flavour Symmetry
Th. Feldmann, Th. Mannel
Lepton-flavour symmetry in the Standard Model is broken by small masses for charged leptons and neutrinos. Introducing neutrino masses via dimension-5 operators associated to lepto…
Role of "Intrinsic Charm" in Semi-Leptonic B-Meson Decays
C. Breidenbach, T. Feldmann, T. Mannel +1
We discuss the role of so-called "intrinsic-charm" operators in semi-leptonic B-meson decays, which appear first at order 1/m_b^3 in the heavy quark expansion. We show by explicit…
Modelling light-cone distribution amplitudes from non-relativistic bound states
Guido Bell, Thorsten Feldmann
We calculate light-cone distribution amplitudes for non-relativistic bound states, including radiative corrections from relativistic gluon exchange to first order in the strong cou…
On the Decay of Soliton Excitations
H. Weigel
In field theory the scattering about spatially extended objects, such as solitons, is commonly described by small amplitude fluctuations. Since soliton configurations often break i…
