Exploring the SMEFT at dimension eight with Drell-Yan transverse momentum measurements
Radja Boughezal, Y. S. Huang, Frank Petriello
Abstract
Effective field theories (EFTs) are used to parameterize searches for new physics in a largely model-independent way. Here, the authors study Drell-Yan processes at the LHC including terms up to dimension 8 in the EFT expansion. They find that these higher-dimension operators can be probed in the future and are potentially important in distinguishing different models.
