[Physics-grads-open] Physics and Astronomy Student Seminar (PASS)

[Pooyan Goodarzi]

Hi all,


We will continue our PASS talks this Monday with a talk by Nika about 
Supernovae and detection of Neutrinos with a Dark Matter detector. 
Please join us on *October 21st (Monday)* at *noon* (from 12:00 pm to 
1:00 pm) in the *Nebula Room* (PHYS 3027).


*Veronika Shalamova, PhD Student*

Monday, 12:00 pm, Conference Room (PHYS 3051)*

*Supernova neutrino detection with DarkSide-20k experiment*

(Or how particle physicists can study supernovae (and neutrinos!) using 
dark matter detectors)*

During a supernova explosion, a significant portion of its energy is 
released in the form of neutrinos. Neutrinos of all flavors escape the 
core well before any light. If detected, they can provide crucial 
information about stellar core collapse and its mechanisms. Future large 
scintillator detectors, designed for direct dark matter searches, will 
be sensitive to supernova neutrinos via coherent elastic 
neutrino-nucleus scattering (CEvNS), opening new avenues in the 
multimessenger approach to supernova physics.

The DarkSide-20k experiment shows great promise due to its ability to 
detect neutrinos through both the CEνNS and charge current (CC) 40Ar(νe, 
e)40K channels. The CEνNS channel provides a flavor-blind measurement of 
the neutrino signal, enabling the normalization of the total supernova 
neutrino flux, while the charge current channel offers a distinct energy 
spectrum and exclusively detects the electron neutrino component. Thus, 
neutrino detection via these two channels presents a unique opportunity 
to explore both supernovae and neutrino physics.*
