Predictions of Physical Observables from Minimal Neutrino Structures
Thomas Hambye
We find all possible seesaw textures which can describe in a natural way the currently observed neutrino oscillation pattern in terms of a minimum number of parameters. Natural her…
Tests of Leptogenesis at Low Energy
Thomas Hambye
The problem of testing leptogenesis from low energy experiments is discussed following three different perspectives. Firstly, we review the prospects that from low energy experimen…
epsilon'/epsilon in the 1/N_c Expansion
T. Hambye, P. H. Soldan
We present a new analysis of the ratio epsilon'/epsilon which measures the direct CP violation in K\toππdecays. We use the 1/N_c expansion within the framework of the effective chi…
Long-Distance 1/N_c Corrections to Density-Density Operators in K --> pi pi Decays
T. Hambye, P. Soldan
In this talk we discuss the general method to calculate loop corrections to Delta S=1 density-density operators in the 1/N_c approach. As a result we present the long-distance evol…
SM Higgs mass bounds from theory
Thomas Hambye, Kurt Riesselmann
The two-loop Higgs mass upper bounds are reanalyzed. Previous results for a cutoff scale few TeV are found to be too stringent. For GeV we find $M_H < 180 \p…
Test of the Equivalence Principle from K Physics
T. Hambye, R. B. Mann, U. Sarkar
A violation of the equivalence principle (VEP) in the Kaon system can, in principle, induce oscillations between and in a manner that need not violat…
