Simple relation for Bs mixing. (2011)
Journal Article
Lenz, A. (2011). Simple relation for Bs mixing. Physical Review D, 84(3), https://doi.org/10.1103/physrevd.84.031501

We reinvestigate a simple relation between the semileptonic CP asymmetry assl, the decay rate difference ΔΓs, the mass difference ΔMs and Sψϕ extracted from the angular analysis of the decay Bs→ψϕ, which is regularly used in the literature. We find t... Read More about Simple relation for Bs mixing..

Triangle relation of dark matter, EDM and CP violation in B0 mixing in a Sspersymmetric Q6 model. (2011)
Journal Article

We consider a recently proposed supersymmetric model based on the discrete Q6 family group. Because of the family symmetry and spontaneous CP violation, the electric dipole moment, the CP violation in the mixing of the neutral mesons, and the dark ma...

Fourth generation Majorana neutrinos. (2011)
Journal Article
Lenz, A., Pas, H., & Schalla, D. (2011). Fourth generation Majorana neutrinos. Physical Review D, 85(7), https://doi.org/10.1103/physrevd.85.075025

We investigate the possibility of a fourth sequential generation in the lepton sector. Assuming neutrinos to be Majorana particles and starting from a recent—albeit weak—hint for a nonzero admixture of a fourth generation neutrino from fits to weak l...

Journal Article
Lenz, A., Nierste, U., Charles, J., Descotes-Genon, S., Jantsch, A., Kaufhold, C., …T'Jampens, S. (2011). Anatomy of new physics in B-B¯¯¯ mixing. Physical Review D, 83(3), Article 036004. https://doi.org/10.1103/physrevd.83.036004

We analyze three different new physics scenarios for ΔF=2 flavor-changing neutral currents in the quark sector in the light of recent data on neutral-meson mixing. We parametrize generic new physics contributions to Bq−B¯¯¯q mixing, q=d, s, in terms... Read More about Anatomy of new physics in B-B¯¯¯ mixing..
