Effective Field Theories
Three lectures in which I give an introduction to effective field theories in particle physics.
متن کاملEffective Field Theories
These lectures introduce some of the basic ideas of effective field theories. The topics discussed include: relevant and irrelevant operators and scaling, renormalization in effective field theories, decoupling of heavy particles, power counting, and naive dimensional analysis. Effective Lagrangians are used to study the ∆S = 2 weak interactions and chiral perturbation theory.
متن کاملEffective Field Theories
An effective field theory (EFT) of a physical system is a theory of the dynamics of the system at energies small compared to a given cutoff. For some systems, low-energy states with respect to this cutoff are effectively independent of ("decoupled from") states at high energies. Hence one may study the low-energy sector of the theory without the need for a detailed description of the high-energ...
متن کاملInterpreting Effective Field Theories
An effective field theory (EFT) is a theory of the dynamics of a physical system at energies small compared to a given cut-off. Low-energy states with respect to this cut-off are effectively independent of states at high energies; hence one may study the low-energy dynamics without the need for a detailed description of the high-energy dynamics. Many authors have suggested that, because of the ...
متن کاملDescribing Nuclear Matter with Effective Field Theories
Nuclear forces have been studied in depth over the past fifty years, leading to excellent phenomenological descriptions. A recent resurgence of interest in this field has been fueled by the promise of systematic results from an effective field theory (EFT) analysis [1]. EFT techniques adapted to many-body systems may give new insight into the properties of nuclei and their connection to QCD. Th...
