An overview of the role of the heaviest known elementary particle, in the context of the Higgs boson and the stability of the Universe.
The top quark, the heaviest elementary particle known, has a profound influence on electroweak physics. Its mass and interactions place it at the intersection of precision tests of the Standard Model (SM) and searches for physics beyond it (BSM). In this work, Marina Cobal e Laura Pintucci provide a comprehensive review of the role of the top-quark mass in electroweak interactions, highlighting theoretical developments, latest experimental measurements, and their implications for Higgs physics, vacuum stability, and possible new physics scenarios.
