Tests of the Higgs properties at the next colliders
We discuss the tests of the fundamental properties of the Standard Model
Higgs boson that can be performed in the next round of experiments.Comment: 8 pages, 4 figures. Talk presented at PLC2005 Warsaw and Kazimierz

Implications of the Higgs discovery for the MSSM
The implications of the discovery of the Higgs boson at the LHC with a mass
of approximately 125 GeV are summarised in the context of the minimal
supersymmetric extension of the Standard Model, the MSSM. Discussed are the
implications from the measured mass and production/decay rates of the observed
particle and from the constraints in the search for the heavier Higgs states at
the LHC.Comment: 21 pages, 27 figures. Review to appear in a special issue of EPJC and
extended version of talks given at various recent conference
Supersymmetry Effects on High-Precision Electroweak Observables
I summarise the virtual effects of the new particles predicted by
supersymmetric extensions of the Standard Model on the high-precision
electroweak observables measured at LEP/SLC, the Tevatron and CLEO. I will then
discuss in some details the two-loop SUSY-QCD corrections to the
parameter.Comment: Latex, 18 pages, 6 figures, sprocl.sty included. Lecture given at X

SUSY-QCD Corrections to Higgs Boson Production at Hadron Colliders
We analyze the next-to-leading order SUSY-QCD corrections to the production
of Higgs particles at hadron colliders in supersymmetric extensions of the
Standard Model. Besides the standard QCD corrections due to gluon exchange and
emission, genuine supersymmetric corrections due to the virtual exchange of
squarks and gluinos are present. At both the Tevatron and the LHC, these
corrections are found to be small in the Higgs-strahlung, Drell-Yan-like Higgs
pair production and vector boson fusion processes.Comment: 11 pages, latex, 3 figures, numerical analysis extended, one figure

On the Minimization of Convex Functionals of Probability Distributions Under Band Constraints
The problem of minimizing convex functionals of probability distributions is
solved under the assumption that the density of every distribution is bounded
from above and below. A system of sufficient and necessary first-order
optimality conditions as well as a bound on the optimality gap of feasible
candidate solutions are derived. Based on these results, two numerical
algorithms are proposed that iteratively solve the system of optimality
conditions on a grid of discrete points. Both algorithms use a block coordinate
descent strategy and terminate once the optimality gap falls below the desired
tolerance. While the first algorithm is conceptually simpler and more
efficient, it is not guaranteed to converge for objective functions that are
not strictly convex. This shortcoming is overcome in the second algorithm,
which uses an additional outer proximal iteration, and, which is proven to
converge under mild assumptions. Two examples are given to demonstrate the
theoretical usefulness of the optimality conditions as well as the high
efficiency and accuracy of the proposed numerical algorithms.Comment: 13 pages, 5 figures, 2 tables, published in the IEEE Transactions on
Signal Processing. In previous versions, the example in Section VI.B
contained some mistakes and inaccuracies, which have been fixed in this
