Example Sentences

At times, the narratives feel disjointed and bogged down in arcane details and enigmatic concepts, for example, in a passage where Bobby discusses the theories of the physicist Steven Weinberg: “Still he figured that if you had these neutrino-nucleon collisions that spun off the W particle and gave you a lepton with the opposite charge you’d have to get a Z particle every once in a while. And since the Z carried no charge this meant that the neutrino coming in would stay a neutrino.”

From New York Times

The Z particle is electrically neutral, and an exchange of such particles is known as a neutral current.

From Washington Post

Smashing electrons into their antimatter counterparts, positrons, results in cleaner collisions that typically produce one Z particle and one Higgs boson at a time, says Bill Murray of The University of Warwick in Coventry, U.K.
