Abstract
Due to its large mass and unique phenomenology the top quark is well suited for searches for new physics, both from and with the top quark. The existence of a light scalar, the Higgs boson, in the Standard Model motivates searches for light top partners. Supersymmetry and Composite Higgs Models are presented as two examples for BSM models in which light top partners naturally emerge.
Furthermore, couplings of Axion-Like Particles (ALPs) to fermions are proportional to the fermion mass which motivates to single out the ALP-top coupling $c_t$. Constraints on $c_t$ from direct and indirect collider searches are presented and compared. Finally, models for 4F operators in the Standard Model Effective Field Theory are discussed and the special features of top-quark operators are pointed out.
