Cosmo: Wednesday, 21/02/2024, 11:00
Paolo Creminelli (ICTP, Trieste)
Positivity Constraints on Lorentz-breaking EFTs
 
The coefficients of the operators of an effective field theory (EFT) are constrained to satisfy certain inequalities, under the (mild) assumption that the UV completion satisfies general requirements of causality and unitarity. I discuss the extension of these ideas to theories where the Lorentz symmetry is spontaneously broken, as it happens in cosmology and condensed matter physics. I explain why the use of the S-Matrix run into immediate problems. Constraints can be derived using dispersive arguments for the 2-point function of conserved currents and applied to models of interest in high-energy and condensed matter.

Cosmo: Wednesday, 28/02/2024, 11:00
Harry Desmond (ICG, Portsmouth)
Four ways of looking at the Radial Acceleration Relation
 
The radial acceleration relation (RAR) is a strong correlation of late-type galaxy dynamics, seeming to describe a mysterious link between baryonic and total dynamical mass. Its properties are so striking that it has even been argued to manifest a new law of gravity in galaxies, the so-called Modified Newtonian Dynamics (MOND). I will describe four recent works analysing the RAR in novel ways. The first (arXiv:2303.11314) marginalises over the galaxy parameters upon which the RAR variables depend, revealing an extremely small intrinsic scatter of 0.034 dex. The second (arXiv:2301.04368) applies a technique called symbolic regression to generate and score all possible functional forms for the RAR, suggesting the data is insufficient to infer Newtonian and deep-MOND limits with statistical confidence. The third (arXiv:2305.19978) uses machine learning to present evidence that the RAR is fundamental: it has no residual correlations, is the tightest projection of galaxies' dynamical parameter space and is uniquely capable of explaining all other dynamical correlations. The last (arXiv:2401.04796) shows that under a “classic” MOND interpretation, the RAR is inconsistent with planetary ephemerides and the kinematics of local wide binaries. I close with an abortive attempt to tie this all together.
