摘要

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 Σmv, h, and Ωbh2 . For?? and , we obtain at 95% confidence.
