- Abstract
- <jats:title>Abstract</jats:title> <jats:p>The Borexino liquid scintillator neutrino observatory has a unique capability to perform high-precision solar neutrino observations thanks to its exceptional radiopurity and good energy resolution (5% at 1 MeV). A comprehensive study of the pp-chain neutrinos was presented that includes the direct measurements of <jats:sup>7</jats:sup>Be, pp and pep neutrino fluxes with the highest precision ever achieved (down to 2.8% in the <jats:sup>7</jats:sup>Be component), the <jats:sup>8</jats:sup>B with the lowest energy threshold, the best limit on CNO neutrinos and the first Borexino limit on hep neutrinos. These results are important to validate the MSW-LMA oscillation paradigm across the full solar energy range and to exclude possible Non-Standard neutrino Interactions (NSIs). In particular the effects of neutrino-flavor-diagonal Neutral-Current (NC) interactions that modify the <jats:italic>v<jats:sub>e</jats:sub>e</jats:italic> and <jats:italic>v<jats:sub>τ</jats:sub>e</jats:italic> couplings while preserving their chiral and flavor structures, have been investigated. At detection, the shape of the electron-recoil spectrum is affected by changes in the <jats:italic>v<jats:sub>e</jats:sub>e</jats:italic> and <jats:italic>v<jats:sub>τ</jats:sub>e</jats:italic> couplings, quantified by the parameters <jats:inline-formula> <jats:tex-math> <?CDATA ${\varepsilon }_{e}^{L/R}$?> </jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:msubsup> <mml:mi>ε</mml:mi> <mml:mi>e</mml:mi> <mml:mrow> <mml:mi>L</mml:mi> <mml:mo>/</mml:mo> <mml:mi>R</mml:mi> </mml:mrow> </mml:msubsup> </mml:mrow> </mml:math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="JPCS_1468_1_012192_ieqn1.gif" xlink:type="simple" /> </jats:inline-formula> and <jats:inline-formula> <jats:tex-math> <?CDATA ${\varepsilon }_{\tau }^{L/R}$?> </jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:msubsup> <mml:mi>ε</mml:mi> <mml:mi>τ</mml:mi> <mml:mrow> <mml:mi>L</mml:mi> <mml:mo>/</mml:mo> <mml:mi>R</mml:mi> </mml:mrow> </mml:msubsup> </mml:mrow> </mml:math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="JPCS_1468_1_012192_ieqn2.gif" xlink:type="simple" /> </jats:inline-formula>. New bounds to all four parameters were obtained, quite stringent compared to the global ones. In particular, the best constraint to-date on <jats:inline-formula> <jats:tex-math> <?CDATA ${\varepsilon }_{e}^{L}$?> </jats:tex-math> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mrow> <mml:msubsup> <mml:mi>ε</mml:mi> <mml:mi>e</mml:mi> <mml:mi>L</mml:mi> </mml:msubsup> </mml:mrow> </mml:math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="JPCS_1468_1_012192_ieqn3.gif" xlink:type="simple" /> </jats:inline-formula> was achieved. A comprehensive summary of all the recent results on solar neutrinos from Borexino is reported in the present paper.</jats:p>
