Discovered in 1995 by CDF and D0, the top quark is the heaviest known
elementary particle until today. Due to its short lifetime and its high
mass, the top quark is an interesting particle to study. In this talk we
will present the latest measurements related to top quark production, such
as the cross section of ttbar and single top. Some searches for new
particles with signatures similar...

This talk will show several highlights of top quark properties measurements, like for example the top quark mass, top quark width and ttbar spin correlations. Furthermore, a selection of beyond the SM top quark searches, in context with top properties measurements, will be presented.

Theory
We present the first direct determination of the running top-quark mass based on the total cross section of top-quark pair-production as measured at the Tevatron.
Our theory prediction for the cross section includes various next-to-next-to-leading order QCD contributions, in particular logarithmically enhanced terms near threshold, the Coulomb corrections at two loops and all explicitly...

We present the latest results on the production of WW, WZ, Wgamma,
Zgamma and ZZ events at the Fermilab Tevatron Collider. The results
are based on the analyses of ~1 -- 5/fb of data collected in ppbar collisions
at sqrt{s}=1.96~TeV by CDF and DO experiments during the Tevatron
Run II. Analyses of the diboson production processes provide crucial
test of the Standard Model, directly...

The Fermilab Tevatron Collider experiments have now each collected almost
7 fb-1 of data, and are steadily increasing their sensitivity to physics
beyond the standard model. In this talk, recent results from searches
in final states containing leptons will be described.

Over 15 years of data taking at the HERA ep collider about 1 fb-1 was gathered in the H1 and ZEUS experiments for neutral and charge current deep inelastic processes at the center-of-mass energy of 320 GeV. This allows to provide the precise determination of the parton distribution functions in the proton and study of the EW effects using data from high Q2, where the contribution from W, Z...

Soft walls are alternative solutions (to RS ones) to the hierarchy problem in warped extra dimensions. Soft walls are generic models where extra scalars are propagating in the bulk and back react on the metric. They replace IR brane by a curvature singularity. Soft walls can provide very peculiar and unambiguous phenomenological features since KK modes (separated from the zero mode by a mass...

We give a general formulation of semi-direct gauge mediation of supersymmetry breaking where the messengers
interact with the hidden sector only through a weakly gauged group. We discuss the resulting MSSM gaugino masses and sfermion squared masses. We comment on how such mechanism can successfully be combined with other mediation schemes.

The experimental signatures of supersymmetric extensions of the Standard Model, such as the Minimal Supersymmetric Standard Model (MSSM), depend on the actual spectrum of superpartners, which in turn is determined by the mechanism responsible for the breaking of supersymmetry and for its mediation to the MSSM. An attractive possibility, known as gauge mediation, is that supersymmetry breaking...

The presence of all R-parity conserving dimension-five and -six
effective operators in the MSSM is analyzed in a model independent way,
with emphasis on their implications to the Higgs sector and to LHC supersymmetry searches.
