First observation of pair of W particles
First observation of a pair of W particles. Electronic display of an event recorded in 1996 at the DELPHI detector at CERN,the particle physics laboratory near Geneva. An electron & positron,accelerated to high energy in CERN's LEP collider,have entered the detector from left & right to annihilate at centre. Their energy materialises as two W particles,a W-plus & a W-minus. Each W decays to a quark & an antiquark which in turn initiates a jet of particles,producing the 4 jets that spray out through the detector (shown in cut- away in pink,purple & blue). The W particles are gauge bosons which,together with the neutral Z particle,are carriers of the weak nuclear force
