Tabulation of astrophysical constraints on axions and Nambu-Goldstone bosons
Astrophysical constraints on the couplings of light and weakly coupled pseudoscalar particles (axions, Majorons, familons, ...) from considerations of various stellar objects are summarized. We tabulate the astrophysical bounds on the mass and the decay constant of Dine-Fischler-Srednicki-Zhitnitsky (DFSZ) axions and Kim-Shifman-Vainshtein-Zakharov (KSVZ) axions, on the triplet Majoron vacuum expectation value v/sub T/, and on the familon breaking scale. The lower bound of the Peccei-Quinn breaking scale in the KSVZ model is generally one order of magnitude weaker than that in the DFSZ model. The most stringent limit on v/sub T/<2 keV is obtained from considerations of Majoron emission from the cores of neutron stars. Bounds on the strength of the 1/r potential mediated by Gelmini-Roncadelli Majorons are also given.
