Hypothetical particle physics models constitute a research area focused on constructing and analyzing theoretical frameworks that extend or modify the Standard Model to explain observed anomalies and unresolved phenomena. These models introduce new fields, symmetries, or spacetime structures, often incorporating entities such as supersymmetric partners, extra gauge bosons, axions, or particles arising from extra dimensions or composite dynamics. Research in this area emphasizes internal consistency (renormalizability, unitarity, anomaly cancellation), compatibility with precision measurements and collider bounds, and predictive power for phenomena such as dark matter, neutrino masses, baryogenesis, and flavor structure, using tools from quantum field theory, effective field theories, and numerical simulations.
One of the main goals of the LHC experiments is to look for signs of new particles, which could explain many of the unsolved mysteries in physics. Often, searches for new physics are designed to look for one specific type ...
