Triple

Target class: low-energy effective theory
Context triple: [Type I supergravity, instanceOf, low-energy effective theory]

• A. electroweak theory
  Electroweak theory is a unified quantum field theory that describes the electromagnetic and weak nuclear forces as different manifestations of a single SU(2)×U(1) gauge symmetry, spontaneously broken via the Higgs mechanism.
• B. weak interaction theory
  Weak interaction theory is the framework in particle physics that describes how particles change flavor via the weak nuclear force, mediated by W and Z bosons and responsible for processes like beta decay.
• C. regularization scheme in quantum field theory
  A regularization scheme in quantum field theory is a systematic procedure for modifying divergent integrals or sums—typically by introducing an auxiliary parameter or cutoff—so that they become finite and mathematically well-defined while preserving as much of the theory’s symmetry and structure as possible.
• D. nonperturbative effect
  A nonperturbative effect is a physical phenomenon that cannot be captured by any finite-order expansion in a small parameter (such as a coupling constant) and instead arises from intrinsically non-linear or exponentially suppressed contributions, like instantons or tunneling.
• E. theory in field theory chosen
  A theory in field theory is a specific, mathematically formulated model that assigns fields and their dynamics to spacetime, defining how physical quantities evolve and interact according to a chosen set of principles and equations.
• F. None of above.
