  T2K Neutrino Oscillation Analysis
VALOR fitting group T2K outputs:
T2K collected data in several periods with different conditions and proton-on-target (POT) exposures, both in neutrino-enhanced Forward Horn Current (FHC) and antineutrino-enhanced Reversed Horn Current (RHC) modes: Run 1 (01-06/2010, FHC: 0.323x1020 POT), Run 2 (10/2010-03/2011, FHC: 1.108x1020 POT), Run 3 (03-06/2012, FHC: 1.579x1020 POT), Run 4 (10/2012-05/2013, FHC: 3.560x1020 POT), Run 5 (05-06/2014, FHC: 0.242x1020 POT and RHC: 0.506x1020 POT), Run 6 (10/2014-06/2015, FHC: 0.190x1020 POT and RHC: 3.505x1020 POT), Run 7 (02-05/2016, FHC: 0.480x1020 POT and RHC: 3.460x1020 POT), and Run 8 (10/2016-04/2017, FHC: 7.170x1020 POT).

  DUNE Sensitivity and Optimization Studies
VALOR fitting group DUNE outputs:
VALOR provides a sensitive joint 3-flavour oscillation and systematics constraint fit for DUNE, and produced the first-ever realistic sensitivity calculations from an end-to-end analysis using full event simulation and reconstruction. The analysis considers several DUNE Near and Far detector event samples. O(50) event samples are used in the latest version of the analysis, constraining O(500) neutrino flux and interaction systematic parameters and providing a realistic DUNE oscillation sensitivity simulation.

  SBN sterile neutrino oscillation analysis
VALOR fitting group SBN outputs:
VALOR provides a joint sterile neutrino oscillation and systematics constraint fit for SBN considering all measured exclusive channels from all three SBN LArTPC detectors (SBND, MicroBooNE, ICARUS). We're also exploring use of VALOR for neutrino interaction cross-section measurements using folded distributions and we're prototyping such analyses for SBND.
