Neutrino-Pair Exchange Long-Range Force Between Aggregate Matter

Understand

We study the long-range force arising between two neutral---of electric charge---aggregates of matter due to a neutrino-pair exchange, in the limit of zero neutrino mass.

• The conceptual basis for the construction of the effective potential comes from the coherent scattering amplitude at low values of t.
• This amplitude is obtained using the methodology of an unsubtracted dispersion relation in t at threshold for s, where (s, t) are the Lorentz invariant scattering variables.
• The ultraviolet behavior is irrelevant for the long-range force.
