W boson

From Brookhaven National Laboratory, Feb. 12, 2018: Fermilab scientist Bo Jayatilaka is quoted in this article on ATLAS’s measurement of the mass of the W boson, a particle that plays a weighty role in a delicate balancing act of the quantum universe.

Scientists of the CDF collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced today (January 8, 2007) the world’s most precise measurement by a single experiment of the mass of the W boson, the carrier of the weak nuclear force and a key parameter of the Standard Model of particles and forces.
