Particle Physics

Europe’s Future Circular Collider, a proposed successor to the Large Hadron Collider, has a clear scientific case but faces uncertainty in its construction. The project is highlighted as a potential revolution in particle physics, though its realization remains unconfirmed.

The article discusses the uncertainty among physicists about the exact number of elementary particles in particle physics. Experiments at the Large Hadron Collider involve smashing protons to break them into elementary particles, though the precise count remains unclear.

Mark Thomson has become the new chief at CERN as particle physics faces deep unknowns and must make tough decisions about its future.

Physicists have discovered a new clue that string theory could be more than just a mathematical fantasy, as simple physics rules naturally produced the telltale fingerprints of string theory. Researchers began with basic rules about particle behavior at extreme energies and found that the equations led to string theory. This finding suggests that string theory may be rooted in physical reality.

A study published in Nature on 08 April 2026 reports a high-precision calculation of the strong coupling constant αs using lattice QCD simulations. This model-free approach significantly reduces theoretical uncertainty and enhances precision tests in particle physics.
