Standard Model Extensions

Standard Model Extensions are theoretical ideas that build upon the current framework of particle physics to address its limitations. The Standard Model explains fundamental particles and forces, but doesn't include gravity or account for dark matter and dark energy. Extensions introduce new particles, forces, or principles—like supersymmetry or extra dimensions—to solve these mysteries. These models aim to expand our understanding of the universe's fundamental workings, guiding experiments at high-energy colliders and other research methods to discover phenomena beyond the Standard Model.
