Flavor Changing Neutral Higgs Bosons in a Supersymmetric Extension based on a Family Symmetry
Naoko Kifune, Jisuke Kubo, Alexander Lenz
A supersymmetric extension of the standard model based on the discrete family symmetry is considered, and we investigate flavor-changing neutral current (FCNC) processes, esp…
The Theoretical status of -mixing and lifetimes of heavy hadrons
Alexander Lenz
In this talk we review the theoretical status of the lifetime ratios of heavy hadrons and of the B-mixing quantities , and . While and suffer from l…
Unparticle physics effects in B_s mixing
Alexander Lenz
We investigate unparticle effects in B_s mixing. In particular we discuss the possibility of reproducing the experimental result of ΔM_s, while having large effects on the mixing p…
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…
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…
Some comments on the missing charm puzzle
Alexander Lenz
In this talk we summarize the status of theoretical predictions for the average number of charm quarks in a B-hadron decay.
