VIRTUAL INPA SEMINAR – Gioacchino Ranucci (INFN) Italy
July 24, 2020 @ 12:00 pm - 1:00 pm
Speaker: Gioacchino Ranucci (INFN) Italy
Title: First detection of solar neutrinos from the CNO cycle with Borexino
Abstract: The liquid scintillator detector Borexino reported recently the direct observation of neutrinos produced in the carbon-nitrogen-oxygen (CNO) fusion cycle in the Sun. This is the first experimental evidence of the existence of such reaction sequence in a star. The CNO solar neutrino interaction rate is 7.2 +3.0 −1.7 counts per day per 100 tons of target at 68% C.L., corresponding to a flux of neutrinos on Earth of 7.0 +3.0 −2.0 ×108 cm−2 s −1. The absence of CNO signal is disfavored at 5.0σ. In this seminar, I will describe the technological effort to stabilize the detector and understand the background, which is at root of this achievement, together with the main features of the analysis procedure exploited to extract the CNO signal.
