One of the fundamental forces is stronger than we thought

The electroweak force, which combines the electromagnetic and weak nuclear forces, may be stronger than previously thought, a discovery that could lead to the identification of new particles. This finding, made by Alessandro Conigli and his team at Johannes Gutenberg University Mainz in Germany, could help resolve several mysteries plaguing our current understanding of particle physics.

The electroweak force plays a role in different processes at various energy levels, such as radioactive decay, and when charged objects interact. However, at extremely high energies and temperatures, such as those found in early stages of the universe and in particle colliders, the two forces combine and become one.

Conigli and his colleagues meticulously calculated several properties of the electroweak force with unprecedented precision, using a technique called lattice quantum chromodynamics (QCD). This technique involves analyzing quantum pairs of virtual particles and their antimatter counterparts to determine how they affect the strength of the electroweak force at different energy levels.

When comparing the newly calculated values to previous calculations using a different method called phenomenological methods, the team discovered a discrepancy of approximately 1 percent. While this may seem small, halving the errors in their calculations significantly improves the accuracy of the results.

This level of precision is crucial for understanding several unexplained phenomena in particle physics and could aid the search for particles beyond the standard model, which currently explains all known forces and particles. The study's findings are particularly valuable for upcoming particle colliders, such as the proposed Future Circular Collider.

These colliders will surpass the precision of existing experiments, and having a solid theoretical foundation will be essential for interpreting the experimental measurements. Conigli believes that this work could potentially be a game-changer in the field, emphasizing the importance of building increasingly sophisticated colliders to further our understanding of the universe.
