Top-quark physics in hadronic collisions

This article is devoted to the processes with participation of t-quark. The top quarks are one most amazing elementary particles. Predictions characteristics various interactions involving -quark have high theoretical accuracy, as well has large production cross section which makes it a unique laboratory for testing Standard Model and beyond. quark important objects in searches new effects. review includes main properties quark, complete analysis experimental measurements possibilities searching manifestations New physics beyond (SM). Interactions t-quarks described framework model-independent way gauge-invariant methods. Another distinctive feature study t-quark absence hadrons containing nature. So there opportunity fundamental  -quark without any hadronization Keywords: Higgs boson, Feynman diagram, model independent gauge invariant method, Form factor, partial width, Model.
