Data Release for "First Measurement of Monoenergetic Muon Neutrino Charged Current Interactions" [Phys. Rev. Lett. 120, 141802 (2018)]


This is a simple website dedicated to allowing comparisons between theoretical predictions and the measurements of KDAR neutrinos made by MiniBooNE. Through the exact same procedure used in the full analysis, an input model is compared to the data and then given a corresponding χ2 value and probability. All comparisons made using this tool should be treated carefully, and any anomalies should be reported to the authors.


The input to the theory-data comparison is a single text file (.txt) which contains the model Tμ spectrum. The file should contain a single column of numbers specifying the model's bin contents in 1 MeV bins (i.e. at 0.5 MeV, 1.5 MeV, etc.). The comparison is shape-only (including endpoint) so the spectrum will be normalized appropriately by the program. An example file for the best fit beta distribution is linked here.

Files can be uploaded using this link. Results of the comparison will be printed in your browser after the file is uploaded.


Below are a few example text files for Tμ models which can be compared to the data:

Genie [C. Andreopoulos et al., Nucl. Instr. Meth. A 614 87 (2010).]
Martini et al. [M. Martini, M. Ericson, G. Chanfray, and J. Marteau, Phys. Rev. C 80 065501 (2009); M. Martini, M. Ericson, and G. Chanfray, Phys. Rev. C 84 055502 (2011).]
Nuance (kappa=1.0, MA=1.23) [D. Casper, Nucl. Phys. Proc. Suppl. 112 161 (2002).]
NuWro [C. Juszczak, Acta Phys. Pol. B 40 2507 (2009); T. Golan, C. Juszczak, and J. Sobczyk, Phys. Rev. C 86 015505 (2012).]
Singh et al. (MA=1.2) [F. Akbar, M. Sajjad Athar, and S.K. Singh, arXiv:1708.00321 [nucl-th] (2017).]

A number of plots comparing these models to the best fit results with stat-only errors for the corresponding end points are shown below. The shaded red region represents the 1σ (χ2min+3.53) stat-only allowed region from our measurement, in consideration of 3 parameters (shape and endpoint). The models and data are normalized appropriately.

98 MeV end point

102 MeV end point

114 MeV end point
