Description
In this talk we show that inclusive single-spin asymmetries (SSAs) with transversely
polarized electrons or protons at a future electron ion collider (EIC) are sensitive to new physics
contributions to electroweak dipole operators of electrons and quarks. We use the Standard Model
Effective Field Theory (SMEFT) to parameterize possible heavy new physics contributions to these
couplings. We show that new physics scales at or beyond the TeV-scale can be probed assuming
realistic EIC run parameters, and that the transverse spin asymmetries are sensitive to
combinations of the dipole couplings complementary to other measurements such as anomalous
magnetic or electric dipole moments.
