Identify evidence for electroweak unification.
The discovery of intermediate vector bosons i.e W and Z particle presents the evidence of electro weak unification. The masses of particle W and Z is around 80 to 90 GeV and were the most massive particle before the discovery of Higgs Boson.

- Theorists have had spectacular success in predicting previously unknown particles. Considering past theoretical triumphs, why should we bother to perform experiments?choose the answer from the drop downLepton. and Baryon conservation: For the reaction, tell me the missing particle @k+h -→ 1° + ? OP+Pp+ ^° + ?
- (a) The most common decay mode of the Ξ− particle is Ξ− → Λ0 + π− . Using the quantum numbers in the table given above, show that strangeness changes by 1, baryon number and charge are conserved, and lepton family numbers are unaffected. (b) Is the decay K+ → μ+ + νμ allowed, given the quantum numbers in the table given above?Determine the electric charge, baryon number, strangeness quantum number, and charm quantum number for the following quark combinations: (a) uds; (b) cu bar; (c) ddd; and (d) d c bar. Explain your reasoning.What evidence is cited to support the contention that the gluon force between quarks is greater than the strong nuclear force between hadrons? How is this related to color? Is it also related to quark confinement?
- where does the piR/2 come from?You are working as an assistant for a physics professor. For an upcoming lecture, your professor asks you to prepare a presentation slide with the following two proposed reactions which might proceed via the strong interaction:(i) π- + p → K0 +Λ0(ii) π- + p → K0 + nOn the slide, the professor wishes for you to show the quark analysis of the reactions, and (a) identify which reaction is observed, and (b) explain why the other is not observed.1
