Disentangling SMEFT operators with future low-energy PVES experiments

TL;DR

Future low-energy PVES experiments like SoLID and P2 can complement LHC data by probing different SMEFT operator combinations and disentangling effects of various operator dimensions, enhancing our understanding of potential new physics.

Contribution

This paper demonstrates how upcoming PVES experiments can provide unique and complementary constraints on SMEFT operators beyond current collider data.

Findings

PVES data complements LHC bounds on SMEFT operators.

PVES helps disentangle effects of dimension-6 and dimension-8 operators.

Low-energy PVES experiments improve the resolution of operator effects.

Abstract

We study the potential of future Parity-Violating Electron Scattering (PVES) data to probe the parameter space of the Standard Model Effective Field Theory (SMEFT). We contrast the constraints derived from Drell-Yan data taken at the Large Hadron Collider (LHC) with projections of the planned PVES experiments SoLID and P2. We show that the PVES data can complement the bounds set by the LHC data in the dimension-6 operator space since it probes different combinations of operators than Drell-Yan. The lower characteristic energy of P2 and SoLID also helps disentangle effects of dimension-6 and dimension-8 operators that are difficult to resolve with LHC Drell-Yan data alone.
