Question
One term in this theory includes a 48-dimensional column vector of quark and lepton fields. For 10 points each:
[10e] Identify this theory, whose Lagrangian contains Yukawa terms which generate particle masses via spontaneous symmetry breaking in its Higgs term. This theory, named for its ubiquity in particle physics, also describes the strong and electroweak interactions.
ANSWER: the Standard Model of particle physics
[10h] The Standard Model’s Yukawa term typically includes this common shorthand in QFT, in which one adds a term represented by these two letters to ensure the masses are real numbers.
ANSWER: + h.c. [accept plus the Hermitian conjugate; accept conjugate transpose; prompt adjoint; prompt transjugate; prompt on dagger]
[10m] The Standard Model Lagrangian also contains a term proportional to the full contraction of a generalization of this quantity. In classical electromagnetism, this quantity represented by F mu nu is given by the exterior derivative of the four-potential.
ANSWER: field strength tensor [accept electromagnetic field strength tensor; accept gauge field strength tensor; accept Faraday tensor; accept Maxwell bivector; prompt on electromagnetic field tensor or electromagnetic tensor alone]
