U (1)
What is the most appropriate transformation for physics according to the text?
Transformations with very small parameters
Which statement best describes the algebraic representation associated with a Lie group?
It involves the study of explicit realizations of the group's action.
In a physical theory with symmetry, what do we study according to the text?
The representations of internal symmetries

Which theory deals with the interaction of charged matter coupled to Aµ (photon)?
Quantum Electrodynamics (QED)
Which theory includes the free propagator of the photon?

In which theory are the Dirac and Weyl equations used to describe free Dirac fields?
Standard Model of Electroweak Interactions
What is the significance of the Large Hadron Collider (LHC) in relation to the Standard Model of electroweak interactions?
It has proven the existence of the Higgs particle, a key component of the Standard Model.
What is the primary achievement of the Standard Model of electroweak interactions?
It accurately describes known experimental facts with high precision.
What is the significance of unification at the electroweak energy scale MW?
