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.
Carnegie Mellon University's Professor Curtis Meyer and his research colleagues explore an uncharted world inside protons and neutrons. For the first time, researchers have provided measurements describing a maximum boundary ...

Amid the many mysteries of quantum physics, subatomic particles don't always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even communicate across vast distances ...

A key objective of many physics studies is to experimentally observe exotic phenomena beyond the Standard Model (SM) that are predicted by theoretical models. These include hidden valley models, which predict the existence ...
Particle physicists have been looking for so-called "sterile neutrinos" for a few decades now. They are a hypothesized particle that would have a tiny mass like the three known neutrinos but would not interact by the weak ...
Dark photons are hypothetical particles that resemble light particles (i.e., photons), but interact weakly with normal matter, which would make them impossible or very difficult to detect using conventional experimental methods. ...
A team led by Stevens professor Igor Pikovski has just outlined how to detect single gravitons, thought to be the quantum building blocks of gravity—and making that experiment real should be possible with quantum technology, ...

In a new study, scientists from Canada have proposed a solution to the final parsec problem of supermassive black hole (SMBH) mergers using self-interacting dark matter.
Despite its immense success in describing the fundamental building blocks of matter and their interactions, the Standard Model of particle physics is known to be incomplete. Experiments around the globe and in space are therefore ...

The Belle II experiment is a large research effort aimed at precisely measuring weak-interaction parameters, studying exotic hadrons (i.e., a class of subatomic particles) and searching for new physical phenomena. This effort ...
