Testing the new CP phase in a Supersymmetric Model with Q6 Family Symmetry by Bs Mixing
Kenji Kawashima, Jisuke Kubo, Alexander Lenz
The new contribution to the non-diagonal matrix element M_12 of the neutral B_s meson system is investigated in a supersymmetric extension of the standard model based on the discre…
mixing in the framework of the HQE revisited
M. Bobrowski, A. Lenz, J. Riedl +1
We reconsider the leading HQE contributions to the absorptive part of the mixing amplitude of neutral mesons by taking also corrections and subleading corrections…
The Nucleon Distribution Amplitudes and their application to nucleon form factors and the transition at intermediate values of
Alexander Lenz, Meinulf Göckeler, Thomas Kaltenbrunner +1
We compare a recent lattice determination of the nucleon distribution amplitudes with other approaches and models. We study the nucleon distribution amplitudes up to twist 6 in nex…
Electroproduction of the N*(1535) resonance at large momentum transfer
V. M. Braun, M. Göckeler, R. Horsley +11
We report on the first lattice calculation of light-cone distribution amplitudes of the N*(1535) resonance, which are used to calculate the transition form factors at large momentu…
How much space is left for a new family?
Markus Bobrowski, Alexander Lenz, Johann Riedl +1
We perform an exploratory study of the allowed parameter range for the CKM-like mixing of hypothetical quarks of a fourth generation. As experimental constraints we use the tree-le…
Threshold Pion Production at Large Momentum Transfers
V. M. Braun, D. Yu. Ivanov, A. Lenz +1
We consider threshold pion electroproduction on a proton target for photon virtualities in the region 1-10 GeV. The S-wave multipoles at threshold, and , are c…
