Event Category: 4D Seminar

Abs: Ill talk about the 4d generalization of recent work investigating operator bases in effective field theories. I’ll present some results from its application to the standard model EFT (like the above sequence for the number of independent operators at dimension 5, 6, 7, etc).

Abstract: We will present a general study of the class of supersymmetric grand unified theories- SaxiGUTs- where the unified and PQ symmetries are broken simultaneously. There has been little interest in SaxiGUTs since the discovery of the axion misalignment mechanism in 1983 that puts the PQ scale far below the GUT scale to avoid overclosure. However, for TeV-scale SUSY, the … Read More

We formulate an effective theory of structure formation (ETHOS) that enables cosmological structure formation to be computed in a vast array of microphysical model of dark matter physics. This framework maps the detailed microphysical theories of particle dark matter interactions into the physical effective parameters that shape the linear matter power spectrum and the self-interaction transfer cross section of non-relativistic … Read More
