Question

Answer the following about spontaneous symmetry breaking in particle physics, for 10 points each.

[10e] The W and Z types of these particles require a spontaneous symmetry breaking to explain their nonzero observed mass. One of these particles named for Higgs that imparts mass was discovered in 2012.

ANSWER: bosons [accept W boson or Z boson or Higgs boson]

[10h] For every symmetry that is spontaneously broken, one of these massless spin-zero bosons appears. Pions, which appear in chiral symmetry breaking, often are regarded as “pseudo-” these bosons.

ANSWER: Nambu–Goldstone bosons [or NGBs; accept pseudo-Nambu–Goldstone bosons]

[10m] The symmetries in spontaneous symmetry breaking imply that there are corresponding conservation laws, according to a theorem named for this mathematician.

ANSWER: Emmy Noether (“NUR-tur”) [or Amalie Emmy Noether; accept Noether’s theorem]
