65. Update on the $hep$ solar neutrino limit from the three-phase SNO dataset

Dr Karin Gilje (University of Alberta)

01/11/2018, 18:00

poster

The spectrum of solar neutrinos from the $pp$ chain has been studied in depth by a variety of underground detectors. However, neutrinos from the $hep$ reaction (${}^3$He $+$ $p^{+}$ $\to$ ${}^4$He $+$ $e^{+}$ + ${\nu }_e$) remain unobserved due to the small theoretical branching ratio ($2\times {10}^{-7}$ per $pp$ termination). The SNO detector has a unique sensitivity to neutrino energies...

52. Neutron detection in the water phase of SNO+ experiment

Dr Yang Zhang (University of Alberta)

01/11/2018, 18:03

poster

Efficient detection of neutrons in water is important because of its physics applications. For example, neutron detection could enable the detection of neutrinos via inverse beta decay or help suppress neutron-accompanied backgrounds. However, observing neutrons in pure water Cherenkov detectors is a challenging task due to the low energy of the 2.2 MeV gamma emitted upon capture. SNO+ is a...

70. LEGEND: The Large Enriched Germanium Experiment for Neutrinoless Double-Beta Decay

Micah Buuck (University of Washington - Seattle)

01/11/2018, 18:06

poster

The lepton number violating process of neutrinoless double-beta decay could result from the physics beyond the Standard Model needed to generate the neutrino masses. Taking different approaches, the current generation of ${}^{76}$Ge experiments, the MAJORANA DEMONSTRATOR and GERDA, lead the field in both the ultra-low background and energy resolution achieved. The next generation of...

49. Energy Reconstruction in NOvA with Regression Convolutional Neural Networks

Prof. Jianming Bian (UC Irvine)

01/11/2018, 18:09

poster

NOvA is a long-baseline accelerator neutrino oscillation experiment. It uses the upgraded NuMI beam from Fermilab and measures electron neutrino appearance and muon neutrino disappearance at its Far Detector in Ash River, Minnesota. NOvA aims to resolve the mass hierarchy, the CP violation and the octant of theta23. We will focus on the development and application of deep learning to the...

72. R&D on Water-based Liquid Scintillator for the Theia experiment

Dr Vincent Fischer Fischer (University of California at Davis)

01/11/2018, 18:12

poster

Recent developments in the field of liquid scintillator chemistry and fast-timing photosensors paved the way for a new generation of large-scale detectors, such as Theia, capable of tackling a broad range of physics issues. Water-based Liquid Scintillator (WbLS) is a novel detection medium that combines the advantages of pure water, including low attenuation, accurate direction reconstruction,...

68. HALO-1kt: A massive helium and lead observatory for supernova neutrinos

Dr Matthew Geske (Gonzaga University)

01/11/2018, 18:18

poster

HALO-1kt is a supernova neutrino observatory which would leverage 1000 tonnes of lead from the decommissioned OPERA experiment to create a low cost and low maintenance neutrino detector. It is to be sited at LNGS, and is intended to operate as a scaled up version of the original HALO. Due to its sensitivity to ${\nu }_e$, it is complementary to water Cherenkov and liquid scintillator-based...

63. Model-independent reconstruction of full flavor supernova neutrino spectra in future large liquid-scintillitor detectors

Dr Huiling Li (Institute of High Energy Physics)

01/11/2018, 18:21

poster

The fortunate observation of neutrino events from the SN1987A explosion in the Large Magellanic Cloud is a milestone in both neutrino physics and neutrino astronomy. The sparse data, however, can't provide us the accurate energy spectra of supernova neutrinos. Currently many worldwide neutrino detectors runnning or under construction have better detection capbilities of core collapse...

54. Search for Supernova Neutrinos with the LVD Experiment

Dr CARLO FRANCESCO VIGORITO (UNIVERSITY and INFN , Torino, Italia)

01/11/2018, 18:24

poster

The Large Volume Detector (LVD) is continuously taking data since 1992 at the INFN Gran Sasso National Laboratory (Italy). The experiment, 1 kton of liquid scintillator organized in 840 counters, is sensitive in the neutrino channels to burst expected from a gravitational stellar collapse. Full detection probability is foreseen in the case of an unexpected event in the Milky Way, d<25 kpc....

62. The Central Detector of JUNO

Mr Yatian Pei (The Institute of High Energy Physics (IHEP))

01/11/2018, 18:27

poster

Jiangmen Underground Neutrino Observatory (JUNO) is an experiment under construction in Southern China. It aims to determine the neutrino mass hierarchy, to measure precisely the oscillation parameters by detecting reactor neutrinos from nuclear power plants, to observe supernova neutrinos, to study the atmospheric, solar neutrinos and geo-neutrinos, and to perform exotic searches. As the...

57. Detection of electron anti-neutrino at Jinping

Mr Jinjing Li (Tsinghua University)

01/11/2018, 18:33

poster

The China Jinping Underground Laboratory (CJPL) with the lowest cosmic-ray muon flux and the lowest reactor neutrino flux of any laboratory is ideal to carry out low-energy neutrino experiments for solar neutrino, geo-neutrino and supernova neutrino physics studies. At present, a 1-ton prototype for Jinping Neutrino Experiment of which the target material is liquid scintillator is deployed in...
