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.
Recent findings from research we have been carrying out at the Large Hadron Collider (LHC) at Cern in Geneva suggest that we might be closing in on signs of undiscovered physics.

Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists in nature. Two principles ...

Neutrinos are extremely lightweight and electrically neutral particles that rarely interact with ordinary matter. Due to these rare interactions, neutrinos can travel across space almost entirely unaffected, carrying information ...
The NA62 Collaboration has dramatically reduced the uncertainty in its measurement of an extremely rare particle decay, in results just presented at the 2026 La Thuile conference.

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 ...
