spec: Now the W boson is also understood to be a fundamental particle in its own right , and it can " couple " at a point in space and time ( called a vertex ) with two other particles whose charges add up to the W charge ( you also have to preserve other things like lepton and baryon number , but we do n't have to go into all of that for this answer ) . This report reviews and analyses current policy and practices regarding the quality of the literacy curriculum and assessment of secondary education in Botswana . But I ' ve dated men from a many different cities and can pretty much tell a man where he is from after a few minutes of conversation . The neutrino from this new generation can ’ t really be light because the number of neutrinos lighter than the Z bosons is measured from the decay rate of Z , and the experimental result is 3 + -0.01 or so . Quarks and leptons are assumed to be fundamental objects , and all their interactions are mediated by force carriers called bosons , with the Z boson being the heaviest carrier of the electroweak force . It should be noted that the officers of the Interfaith Dialogue Community be officially registered as full-time students at The University of Virginia . We choose the initial wave function to describe a condensate , where the N bosons are all in the same one-particle state . Coal is transported from the working sections to the surface via conveyor belts . The results , project scientists say , will be substantially increased accuracy of short-term weather predictions , improved tracking of severe weather events like hurricanes and advances in climate research . Chavez might retaliate against such actions by kicking U.S. oil companies out of Venezuela , but this would only increase the Venezuelan state 's international litigation costs . In this regard , with ASU pushing so hard and fast for new space , it may be falling victim to its own success . That 's because the Z0 boson is short-lived and decays to certain other particles ; the number of these particles influences the decay process .
