Record Precision Achieved in Measuring Higgs Boson's Mass at Large Hadron Collider

The ATLAS experiment at CERN has achieved a record precision measurement of the Higgs boson's mass, reporting a value of 125.11 billion electronvolts with minimal uncertainty. This measurement, derived from a combination of diphoton and four-lepton channels, is crucial for understanding the fundamental structure of the Universe and testing the Standard Model. The advanced calibration techniques and powerful reconstruction algorithms used in the analysis contributed to this unprecedented level of precision.
