Abstract
From 21 independent Baryon Acoustic Oscillation (BAO) measurements we obtain the following sum of masses of active Dirac or Majorana neutrinos: , where and . This result may be combined with independent measurements that constrain the parameters Σm v , h, and Ω b h 2 . For and , we obtain at 95% confidence.
