Description

Third generation quarks, in particular the heavy top quark, can be a rivileged way to access physics beyond the Standard Model (BSM). Vector-like quarks, those decay involve third-generation quarks, appear in BSM theories aiming at solving the hierarchy problem. BSM models also predict new resonances that decay preferably into heavy quarks. The seminar resents newest results from this search program along with some of its crucial elements, as the reconstruction and identification of top quarks and the understanding of the SM top quark production.
