Lifetimes and oscillations of heavy mesons
Alexander Lenz
We review the theoretical status of the lifetime ratios and and of the mixing quantities , and . We show that the ratio $Δ…
Theoretical update of Bs-Bs-bar mixing
Alexander Lenz, Ulrich Nierste
We update the theory predictions for the mass difference $\dm_s$, the width difference $\dg_s$ and the CP asymmetry in flavour-specific decays, , for the \bbs syste…
Deep Inelastic Pion Electroproduction at Threshold
V. M. Braun, D. Yu. Ivanov, A. Lenz +1
We consider the cross section of the deep inelastic pion electroproduction on a proton target at threshold for Q^2 in the region 5-10 GeV^2. The corresponding amplitudes are descri…
Nucleon Form Factors in QCD
V. M. Braun, A. Lenz, M. Wittmann
We calculate the electromagnetic and the axial form factors of the nucleon within the framework of light cone sum rules (LCSR) to leading order in QCD and including higher twist co…
Higher-Twist Distribution Amplitudes of the K Meson in QCD
Patricia Ball, V. M. Braun, A. Lenz
We present a systematic study of twist-3 and twist-4 light-cone distribution amplitudes of the K meson in QCD. The structure of SU(3)-breaking corrections is studied in detail. Non…
