Particle and high energy physics seeks to understand the fundamental constituents of matter and the interactions that govern them across the smallest distance scales and highest energies. The Standard ...

Dark matter particles could be mediators of the interaction between electrons and atomic nuclei, as shown by a study ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science’s most ...

Particle accelerators reveal the heart of nuclear matter by smashing together atoms at close to the speed of light. The high-energy collisions produce a shower of subatomic fragments that scientists ...

In the hunt for new physics beyond the Standard Model, scientists are now looking closely at an unusual class of particle interactions called neutral triple gauge couplings (nTGCs). These interactions ...

The elusive Higgs particle has the power to undo physics as we know it. The fact that it hasn't could have big implications about the nature of the universe. When you purchase through links on our ...

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

The muon mismatch was caused by calculation limits, not a new force. Improved methods bring theory and experiment into close ...

Quantum computers are beginning to become powerful tools for studying some of the most fundamental forces in the universe – and some of the trickiest to understand. Two experiments have used them to ...

A major obstacle in calculating the muon’s behavior is the strong force, the most powerful of the four fundamental forces, along with gravity, electromagnetism, and the weak force. It binds quarks ...
