百科解釋
In particle physics, V was a generic name for heavy, unstable subatomic particles that decay into a pair of particles, thereby producing a characteristic letter V in a bubble chamber or other particle detector. Such particles were first detected in cosmic ray interactions in the atmosphere in the late 1940s and were first produced using the Cosmotron particle accelerator at Brookhaven National Laboratory in the 1950s.
