Removing flat directions in standard model EFT fits: How polarized electron-ion collider data can complement the LHC
Radja Boughezal, Frank Petriello, Daniel Wiegand
Abstract
Effective field theory is used to characterize deviations from the Standard Model, but requires many measurements to explore the large parameter space. In this paper, the authors demonstrate how the upcoming Electron-Ion Collider at Brookhaven National Lab can improve constraints on four-fermion operators in the Standard Model effective field theory approach. Thanks to its expected polarization capabilities the EIC can help disentangle combinations of operators which the LHC can't resolve.
