With the advent of the LHC machine, we expect our vision of the world at microscopic scales to be dramatically transformed by major discoveries which will solve the shortcomings of the Standard Model of particle physics.
Supersymmetry (Susy) naturally solves some of these shortcomings by associating with each Standard Model particle a partner having the same gauge interactions. The lightest supersymmetric partner of the top quark (stop1), benefitting from a large mixing between the chiral Susy partners of the top quark, might be the lightest squark, whose discovery would be an opening to the Susy world.
During this seminar, I will review phenomenological arguments ranging from the Higgs to the Dark Matter sector as motivations for searching the stop1 at the LHC. Finally, I will present a strategy for a coherent stop1 search versus the stop1 mass, which is as model independent as possible
