Information on precautionary site access restrictions to Fermilab's Batavia site in response to coronavirus/COVID-19
We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics.
As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.

indico search will be reestablished in the next version upgrade of the software: https://getindico.io/roadmap/

Description

The hypothesis is of the existence of a fourth neutrino state comes from some experimental anomalies that cannot be explained with the present three lightest neutrinos. This demand the existence of sterile neutrinos. The sterile neutrino appears in many extensions of Standard Model, in the 3 + 1 model that considers three active neutrinos and one sterile state and also in Large Extra Dimensions (LED) models where some particles can travel through extra dimensions compacted in radius with magnitude from Planck scale, which are hidden from experiments, to few millimeters. LED models produce an infinite tower of sterile neutrinos. As the sterile neutrino states do not have any weak interaction, they can only be detected indirectly through their mixing with the active neutrinos and because of this, we want to study the neutrino oscillation physics when these LED sterile neutrinos are included. Then we will test the sensitivity of LED parameters based on the exclusion region of 3 + 1 model for the three LAr-TPC detectors located along the Booster Neutrino Beam (BNB) at Fermilab which are part of a Short Baseline Neutrino (SBN) program, that will perform the most sensitive search to date for sterile neutrinos at the eV mass-scale through both appearance and disappearance oscillation channels. We also investigated the capability of SBN to differentiate the LED model from the 3 + 1 neutrino model.
