Standard Model

There are an array of experiments, like the Muon g-2 experiment at Fermilab, that are looking to see if an elusive fifth force might be at work.

Experiments that uncover the possibility of new forces, like the Muon g-2 experiment at Fermilab, might help researchers examine the trajectories of well-documented asteroids in hopes of detecting anomalies that could provide evidence of such a fifth force.

The deviant behavior of a tiny particle called the muon might point to undiscovered forms of matter and energy in the universe. Or it might not.

To address the lingering questions of the Standard Model of Physics, particle physicists have been planning the next-generation colliders. Fermilab could be the site of a future muon collider, but future colliders will be the efforts of the international physics community.

In the quest to understand the fundamental forces that govern our universe, the Standard Model of particle physics has long stood as the cornerstone. Recent experimental discrepancies like those from Fermilab’s Muon g-2 experiment, have stirred the physics community, suggesting that the muon’s behavior under magnetic fields might not fully align with Standard Model prediction.

Physicists on the CMS experiment announce the most elaborate mass measurement of a particle that is notoriously difficult to study and has captivated the physics community for decades.

Physicists from the Muon g-2 collaboration have measured the magnetic moment of the muon to unprecedented precision and the collaboration’s latest work has been published in Physical Review D. What is next for Muon g-2?

There are patterns seen in quarks and leptons that remain unexplained, but it can be hypothesized that quarks and leptons might be created of still smaller particles. Does the Standard Model allow for an even smaller layer of matter to exist?

The unusually large Muon has threatened the Standard Model for decades, but new data parks the particle inside the confines of established physics. The BMW Collaboration’s recently posted research suggests the difference between the muon’s predicted anomalous magnetic moment and that predicted by the Standard Model is not as large as previous findings suggested.

How are cosmology and particle physics connected? Observing the motions of stars and galaxies can reveal the influence of as-yet-undiscovered particles, while studying fundamental particles in the lab can tell us about the birth and evolution of the cosmos.
