Indirect searches for BSM at the EIC

The next stage of searches for beyond-the-Standard Model (SM) physics will rely increasingly upon indirect probes of heavy new physics. The appropriate theoretical framework in which to formulate these searches is the SM Effective Field Theory (SMEFT), formed by adding higher-dimensional operators to the SM suppressed by a high energy scale below which heavy new fields are integrated out. Since the deviations induced by many classes of SMEFT operators grow with energy it is often assumed that the strongest probes of these effects will come from the LHC. We show in this talk that the LHC contains blind spots in its coverage of semi-leptonic four-fermion operators. We demonstrate that a future EIC, with the possibility of polarizing both electron and ion beams, will play a crucial role in covering these blind spots and making sure that the full parameter space of beyond-the-SM possibilities is investigated.
