===== Description=====
The Understanding Experimental Neutrino Anomalies topical group will cover and discuss ideas on sterile neutrino oscillations, including experiments or theoretical models on 3+1 and 3+N scenarios, as well as other conventional and BSM Physics that can explain current short-baseline anomalies or alter disappearance/appearance neutrino oscillation probabilities.


===== Topics=====
The topics covered and discussed in the group include, but are not limited to:

Phenomenology: 
	* 3+N Sterile Neutrino Mixing
	* Neutrino Decay
	* Large Extra-Dimensions
	* PMNS Non-Unitarity Tests
	* NSI
	* Hidden Neutrinos

Experimental Signatures:
	* Muon Neutrino/Antineutrino Disappearance
	* Electron Neutrino/Antineutrino Disappearance
	* Electron Neutrino/Antineutrino Appearance
	* NC Disappearance 

Source/Baseline Types:
	* Accelerator Long-Baseline Experiments
	* Accelerator Short-Baseline Experiments
	* Atmospheric Neutrinos
	* MeV-scale Reactor
	* MeV-scale Radiological
	* Cosmological and Astrophysical 

===== Meetings and Communication  =====
  * Meetings will be via Indico.   An Indico link will be setup with presentation slides and actions items for the meetings
  *  General Neutrino Frontier calendar meetings are found in [[https://snowmass21.org/frontiermeetings/ | here ]].

===== LOI Submission=====
Between April 1, 2020 to August 31, 2020, we are requesting submission of Letters of Interest (LOIs) related to the Sterile Neutrino Physics topics listed above.
   * Please follow this  [[https://snowmass21.org/loi| link]] for instructions on how to submit an LOI.
   * When uploading your LOI, please make sure to select "FRONTIERS IN NEUTRINO PHYSICS (NF)” as the Primary Category, and "NF02" (Sterile Neutrinos) as the topic. 

We look forward to receiving your feedback and LOI!
