Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

VIRTUAL INPA SEMINAR – Zara Bagdasarian (UC Berkeley)

April 3, 2020 @ 12:00 pm - 1:00 pm

Speaker: Zara Bagdasarian (UC Berkeley)

Title: Borexino. Sun. Earth. Neutrinos

Abstract:

Borexino experiment is a 280-ton liquid scintillator detector located at a 3800 m w.e. depth in the Laboratori Nazionali del Gran Sasso (Italy). In more than 12 years of data taking, Borexino has demonstrated how its unprecedented radio-purity led to exploring a wide range of neutrino physics questions in previously poorly explored low energy range.
In 2018-2020, Borexino published a comprehensive study of pp-chain solar neutrinos, which sets new milestones in the solar neutrino measurement precision. These neutrinos are the products of the pp-chain of nuclear fusion reactions generating more than 99% of the Sun’s energy. We use the gathered data as a two-fold tool to explore both neutrino and solar physics questions.
Moreover, Borexino is one of only two detectors in the world who have measured geoneutrinos. The results, published in 2020, feature increased statistics and the new elaborate analysis. With this update, we have now been able to access 53 geoneutrino events – almost twice as many as in the result published by the collaboration in 2015. The geological interpretations of this measurement will also be discussed in the talk.
