Beam-Normal Single-Spin Asymmetry in Pb at low energy: discrepancy resolved or new kinematic puzzle?
A. Esser, N. Kozyrev, K. Aulenbacher +17
A longstanding discrepancy between measured and predicted beam-normal single-spin asymmetries in elastic electron scattering off Pb has challenged our understanding…
The MESA physics program
