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.
The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists has carried out one of ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe capable of producing such ...

Axions are hypothetical light particles that could solve two different physics problems, as they could explain why some nuclear interactions don't violate time symmetry and are also promising dark matter candidates. Dark ...
A professor at the University of Cincinnati and his colleagues have figured out something two of America's most famous fictional physicists couldn't: how to theoretically produce subatomic particles called axions in fusion ...

Scientists search for "decaying" dark matter (DDM) because it offers unique signatures like specific X-ray or gamma-ray lines or neutrino signals not seen in normal matter, potentially revealing dark matter's particle nature, ...

There is a limit to how big we can build particle colliders on Earth, whether that is because of limited space or limited economics. Since size is equivalent to energy output for particle colliders, that also means there's ...
