02:04:24 asimina arvanitaki: theta dot is very large — is there any back reaction from decay to plasmons? 02:29:01 David Tanner: Are all three couplings linked: -photon, -electron -nucleon? So if I pick a mass, I can look at any of these for either a detection or a limit? 02:32:04 Gray Rybka: perhaps a neutrino mass scale measurement would point to an axion mass then? 02:34:36 asimina arvanitaki: this is the paper I am talking about 02:34:42 asimina arvanitaki: https://arxiv.org/pdf/1607.01786.pdf 02:34:49 asimina arvanitaki: there are always tachyonic modes
