Graduate Seminar - The Solar Neutrino Problem

Speaker

Paul Deguire

Abstract

Neutrinos, elementary particles involved in weak interaction reactions, play an important role in phenomena like nuclear fusion within stars, including our very own sun. The elusive nature of neutrinos makes the identification of the solar ones a remarkable challenge. The latter half of the 20th century witnessed monumental efforts in the development of neutrino detectors, leading to the spectacular confirmation of solar neutrinos reaching Earth. However, experimental results did not agree with theoretical predictions. Observatories observed only about one-third of the expected neutrino count, making the scientific community its understanding of the nature of neutrinos and the mechanisms governing their behavior and giving rise to the solar neutrino problem. In this presentation, I will provide a brief overview of neutrino physics, talking about the technics used to detect neutrinos and elaborating on the solar neutrino problem.

Everyone is welcome to join! We would love to see more undergrad students come out to learn about the exciting research being carried out in the department.
 
There will be snacks available throughout the talk in MacN 222, as well as refreshments available beforehand in the lunchroom on the 2nd floor of MacN. 
 
For those unable to attend in person, the talk will also be streamed live over teams at the following link:
