Talk presentation
Naturalness arguments for weak-scale supersymmetry favour supersymmetric partners of the third generation quarks with masses not too far from those of their Standard Model counterparts. Real and virtual production of third generation squarks via decay of a gluino can be significant if the mass of the gluino does not exceed the TeV scale. The talk presents recent ATLAS results from searches for...

Higgs and New Physics
Talk presentation
In this talk, the latest results from CMS on searches for new physics in final states with four W bosons and multiple b-quarks are presented using up to 20/fb of data from the 8TeV LHC run of 2012. This final state is of special importance in the context of the search for third generation squarks in gluino or sbottom cascade decays. The four W final state is reconstructed in a variety of final...

Higgs and New Physics
Talk presentation
The recent discovery of a Higgs boson in the mass range of about
$m_H=126$~GeV has also an impact on further new physics searches.
Based on the recent LHC results and the currently still negative results for Supersymmetry or other beyond Standard Model Physics, one has to develop strategies for finding hints for new physics at future colliders.
Recently strong activities in Japan towards...
