Neutrino lasing in the Sun

Butler, Malcolm; Malaney, R. A.; Starkman, G. D. (American Physical Society, 1994-06-01)

Applying the phenomenon of neutrino lasing in the solar interior we show how the rate for the generic neutrino decay process [nu] [right arrow] fermion + boson can in principle be enhanced by many orders of magnitude over ...
Neutrino-deuteron scattering in effective field theory at next-to-next-to-leading order

Butler, Malcolm; Chen, Jiunn-Wei; Kong, Xinwei (American Physical Society, 2001-03)

We study the four channels associated with neutrino-deuteron breakup reactions at next-to-next-to-leading order in effective field theory. We find that the total cross section is indeed converging for neutrino energies up ...
