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.
Physicists at UC Santa Barbara have extended the search for evidence of microscopic black holes produced at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN). The formation of these ...

Dark matter is one of the oldest open problems in physics. It makes up most of the matter in the universe and shapes how galaxies form and move, yet no one has ever directly detected it. Physicists have proposed dozens of ...

For decades, a theory in physics has postulated the existence of a mirror world whose interaction with our own reality is extremely feeble. The particles in this mirror universe are also thought to be candidates for dark ...

It's been said that a finely tuned ear knows the size and shape of a piano by merely listening to the instrument's notes. An international team of physicists has now devised an analogous approach to detect the universe's ...

What if the Higgs boson found in 2012 is not alone but is the only sibling we have encountered so far? Scientists at CERN discovered the particle that year, and it was a major discovery because it explained how other particles ...

Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?
