Update on Fermion Mass Models with an Anomalous Horizontal U(1) Symmetry
P. H. Chankowski, K. Kowalska, S. Lavignac +1
We reconsider models of fermion masses and mixings based on a gauge anomalous horizontal U(1) symmetry. In the simplest model with a single flavon field and horizontal charges of t…
Supersymmetry (at large tan beta) and flavour physics
P. H. Chankowski, J. Rosiek
Recent development in exploring flavour dynamics in the supersymmetric extension of the Standard Model is reviewed. Emphasis is put on possible interesting effects in b-physics ari…
Neutrino Unification
P. H. Chankowski, A. Ioannisian, S. Pokorski +1
Present neutrino data are consistent with neutrino masses arising from a common seed at some ``neutrino unification'' scale . Such a simple theoretical ansatz naturally leads…
Haggling over the fine-tuning price
P. H. Chankowski, J. Ellis, M. Olechowski +1
We amplify previous discussions of the fine-tuning price to be paid by supersymmetric models in the light of LEP data, especially the lower bound on the Higgs boson mass, studying…
ALEPH Four-Jet Excess, and Parity Violation
P. H. Chankowski, D. Choudhoury, S. Pokorski
We review briefly the indications for some relatively light superpartners based on the ~ ~anomaly and discuss the dependence of the potential increase in on the assumpti…
Precision tests of the MSSM
P. H. Chankowski, S. Pokorski
We present the results of a first global fit to the electroweak observables in the MSSM. The best fit selects either very low or very large values of ~ ~and, correspondingly…
Precision Tests of the MSSM
P. H. Chankowski, S. Pokorski
The LEP data and the measurement of confirm the electro weak symmetry breaking by the Higgs mechanism with (2--3)\% accuracy. For the Higgs boson mass, fits to the present da…
Universality in Decays and Constraints on the Slepton Masses
P. H. Chankowski, R. Hempfling, S. Pokorski
The leptonic decays are calculated at the 1-loop level in the Minimal Supersymmetric Standard Model. The deviation from the universality is studied as a function of t…
