KamLAND-Zen 800 releases first results at TAUP 2019

10/7/2019

 
Picture
Aobo Li presents the first KamLAND-Zen 800 results at TAUP 2019 in Toyama, Japan.  He incorporated the first independent Bayesian analysis framework into the first result and we are working to improve KamLAND-Zen's sensitivity to neutrinoless double beta decay using deep learning inside this framework.

ACED delivers precision neutron capture cross section results

5/30/2019

 
The Argon Capture Experiment at DANCE (ACED) measured the cross section for neutrons capturing on argon, a reaction that is expected to happen frequently when neutrons are produced by neutrino interactions in the DUNE experiment.

SNO+ turns out first physics from water phase!

3/5/2019

 
SNO+ has been taking data with a pure water detector since May 2017.  Results have recently been published in Physical Review D for a very low background measurement of solar neutrinos (https://arxiv.org/abs/1812.03355) and a search for a special kind of nucleon decay that would indicate new physics beyond the Standard Model (https://arxiv.org/abs/1812.05552).

Zach Collins Successfully Defends Senior Thesis

Zach studied how supernova neutrinos could interact in the DUNE detector and also made predictions for interactions in a small prototype.  Job well done, Zach!

SNO+ begins search for "invisible" mode of nucleon decay

5/1/2017

 
Picture
The SNO+ detector, recently filled with ultra pure water, is searching for neutrons that spontaneously decay into three neutrinos.  The neutrinos coming from this decay would leave the detector undisturbed (they're invisible to us).  However, the disappearance of the neutron from an oxygen nucleus will often emit several gamma rays, which would readily be seen inside SNO+.  This special type of nucleon decay is one of the dominant modes predicted by particle physics models with Universal Extra Dimensions.

SNO+ event display lights up the night

3/1/2017

 
Picture
After years of hard work by many people, the SNO+ detector comes to life.  This is a 3D map of all the photomultiplier tubes in SNO+.  The colors indicate how many photons were seen by each photomultiplier (red = high, blue = low).  A ring-shaped image, like the one recorded here, is typically produced when a neutrino from the atmosphere interacts in the water-filled volume of the detector.
