SUMMARY:Prospects for the Detection of Solar Neutrinos in DARWIN via Elast

DESCRIPTION:The DARWIN observatory\, a proposed experiment that would util
 ize tens of tonnes of liquid xenon to directly detect dark matter\, will a
 dditionally exhibit sensitivity to solar neutrinos via elastic electron sc
 attering. DARWIN will have the potential to measure the fluxes of five sol
 ar neutrino components: pp\, 7Be\, 13N\, 15O and pep. A high-statistics ob
 servation of pp neutrinos would allow us to infer the values of the weak m
 ixing angle and the electron-type neutrino survival probability\, in the e
 lectron recoil energy region from a few keV up to 200 keV. An observation 
 of pp and 7Be neutrinos would constrain the neutrino-inferred solar lumino
 sity down to 0.2%. A combination of all flux measurements would distinguis
 h between the high (GS98) and low metallicity (AGS09) solar models with 2.
 1-2.5σ significance\, independent of external measurements from other exp
 eriments. Finally\, the neutrino capture process on 131Xe may be observabl
 e with a target depleted of 136Xe
