====== TF02: Effective field theory techniques ====== Co-Conveners: Patrick Draper (UIUC), Ira Rothstein (CMU) ====== Description====== Effective field theory (EFT) is a conceptual and analytic framework underpinning much of modern theoretical physics. EFT is a methodology which allows one to describe low energy physics while systematically accounting for the effects of high energy physics. EFTs have been developed to address a diverse range of fields, including QCD, Beyond the Standard Model physics, classical and quantum gravity, and condensed matter physics. This topical group will focus on the forefront of EFT research in the aforementioned fields as well as the theoretical limits imposed on EFTs when they are embedded in theories of quantum gravity. Subtopics to be explored: * SCET * SMEFT * Naturalness problems * Swampland/WGC * EFTs from amplitudes * Connections to CMT * Anomaly matching techniques * EFT for inflation * NRGR * EFT of Dark Matter ====== Submitted LOI ====== Here is the list of submitted LOIs to this topic. First index before "/" corresponds to the primary frontier used for the submission. {{url>https://www.snowmass21.org/docs/files/list.php?frontier=TF2 noborder 95%,600px}}
