Advancements in Higgs Boson Measurement: Unprecedented Precision and Rare Interactions Explored

Physicists using the Large Hadron Collider have obtained the most precise measurement yet of the mass of the Higgs boson, the elusive particle that gives other fundamental particles their mass. The researchers combined several mass measurements based on the particle's decay with more precise calibrations, resulting in a Higgs boson mass of 125.11 gigaelectronvolts (GeV) with an uncertainty of 0.11 GeV. This measurement helps refine our understanding of the Higgs boson's properties and its interactions with other particles, while also providing an opportunity to test predictions of the Standard Model of Particle Physics and potentially detect deviations that could hint at new phenomena beyond our current understanding.
