Erratum: Vacuum stability of the effective Higgs potential in the minimal supersymmetric standard model [Phys. Rev. D90, 035025 (2014)]

Autor: Guillaume Chalons, Ulrich Nierste, Markus Bobrowski, Wolfgang Hollik

Publikováno v: Physical Review D. 92

The parameters of the Higgs potential of the Minimal Supersymmetric Standard Model (MSSM) receive large radiative corrections which lift the mass of the lightest Higgs boson to the measured value of 126 GeV. Depending on the MSSM parameters, these ra

Charm mixing in the Standard Model

Autor: Alexander Lenz, Markus Bobrowski

Publikováno v: Proceedings of Science (PoS), 2010, Vol.ICHEP2010, pp.193 [Peer Reviewed Journal]

In this talk we report on a study on the mixing of neutral charmed mesons and argue that, at the present stage, a CP violating weak phase of the order of some per mille can not be excluded in the Standard Model. It is shown how some, seemingly reason

How large can the SM contribution to CP violation in $D^0-\bar D^0$ mixing be?

Autor: J. Rohrwild, Alexander Lenz, Johann Riedl, Markus Bobrowski

We investigate the maximum size of CP violating effects in $D$-mixing within the Standard Model (SM), using Heavy Quark Expansion (HQE) as theoretical working tool. For this purpose we determine the leading HQE contributions and also $\alpha_s$ corre

How much space is left for a new family of fermions?

Autor: Juergen Rohrwild, Alexander Lenz, Johann Riedl, Markus Bobrowski

Publikováno v: Physical Review D. 79

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-level determinations of the 3x3 Cabibbo-Kobayashi-Maskawa (CKM) elements
