Abstract

We present a precise measurement of the deuteron longitudinal spin asymmetry A₁^d and of the deuteron spin-dependent structure function g₁^d at Q² < 1 (GeV / c)² and 4 × 10^-5 < x < 2.5 × 10^-2 based on the data collected by the COMPASS experiment at CERN during the years 2002 and 2003. The statistical precision is tenfold better than that of the previous measurement in this region. The measured A₁^d and g₁^d are found to be consistent with zero in the whole range of x.

The statistical precision is tenfold better than that of the previous measurement in this region. The measured A1d and g1d are found to be consistent with zero in the whole range of x.

AB - We present a precise measurement of the deuteron longitudinal spin asymmetry A1d and of the deuteron spin-dependent structure function g1d at Q2 < 1 (GeV / c)2 and 4 × 10-5 < x < 2.5 × 10-2 based on the data collected by the COMPASS experiment at CERN during the years 2002 and 2003. The statistical precision is tenfold better than that of the previous measurement in this region. The measured A1d and g1d are found to be consistent with zero in the whole range of x.
