title = "Cosmological concordance or chemical coincidence ? Deuterated molecular hydrogen abundances at high redshift",
abstract = "We report two detections of deuterated molecular hydrogen (HD) in QSO absorption-line systems atz > 2. Toward J2123-0500, we find N(HD) = 13.84 ± 0.2 for a sub-Damped Lyman Alpha system (DLA) with metallicity ≃0.5Z",
