Résumé fourni par la source

Utilizing the 2012 transversely polarized proton data from the Relativistic Heavy Ion Collider at Brookhaven National Laboratory, the forward η -meson transverse single-spin asymmetry ( A N ) was measured for p ↑ + p collisions at s = 200 GeV as a function of Feynman-x ( x F ) for 0.2 < | x F | < 0.8 and transverse momentum ( p T ) for 1.0 < p T < 5.0 GeV / c . Large asymmetries at positive x F are observed ( ⟨ A N ⟩ = 0.086 ± 0.019 ), agreeing well with previous measurements of π 0 and η A N , but with reach to higher x F and p T . The contribution of initial-state spin-momentum correlations to the asymmetry, as calculated in the collinear twist-3 framework, appears insufficient to describe the data.
