New physics study changes understanding of the forces of the universe

A group of physicists has conducted the most precise measurement to date of the electroweak interaction, showing a discrepancy of about 1% with established theories. The results, published in Physical Review D, indicate that one of the fundamental forces is stronger than previously thought, challenging the completeness of the Standard Model and opening the path to the search for new physics.

A group of physicists has conducted the most precise measurement to date of the electroweak interaction, the results of which were published in the prestigious journal Physical Review D. Using an advanced method of lattice quantum chromodynamics, the scientists determined that the actual values exceed previous calculations by about 1%. In the scale of fundamental physics, this discrepancy is enormous and challenges the completeness of the modern Standard Model. The obtained data indicate that one of the main forces of the universe is stronger than previously assumed. These new high-precision measurements are critically important for future experiments at particle accelerators, including the Large Hadron Collider. Scientists hope that the refined data will help discover new elementary particles and phenomena that will push physics beyond its usual limits, in particular to explain the nature of dark matter, which accounts for about 85% of all mass in the universe.
