Alexis A. Aguilar-Arevalo

Since January of 2009 I am working at the Instituto de Ciencias Nucleares of the U.N.A.M. in Mexico City.

From January to December of 2008 I worked on the PIENU experiment as a post-doc in the TRIUMF laboratory located in Vancouver B.C., Canada.

From June of 2003 to December of 2007 I conducted my research at Fermilab as a graduate student with Columbia University working on the MiniBooNE experiment.

I graduated on December 20 of 2007, and my Ph.D. degree was awarded by Columbia University on February of 2008.

Background ( full CV, abridged CV )

  • Ph.D from Columbia University . Ph.D. Thesis: An Improved Neutrino Oscillations Analysis of the MiniBooNE Data
  • Undergraduate and Masters degree from the Universidad Nacional Autonoma de Mexico
  • Undergraduate Thesis: "Oscilaciones de neutrinos : el experimento DAR en LSND" (1999)
  • MiniBooNE:

    The MiniBooNE neutrino oscillations experiment was designed to confirm or refute the antinumu->antinue oscillations signal observed by the LSND experiment, conducted at the Los Alamos National Laboratory from 1993 through 1998. The LSND signal would have important implications for the Standard Model if due to two-neutrino oscillations, requiring the existence of at least one non interacting neutrino (sterile).

    Excerpt from the abstract of the 2013 anti-nue appearence paper (with updated nue appearance results):

    ... "An event excess of 78.4+-28.5 events (2.8 sigma) is observed in the energy range 200 < EnuQE < 1250 MeV. If interpreted in a two-neutrino oscillation model, numubar->nuebar, the best oscillation fit to the excess has a probability of 66% while the background-only fit has a chi2 probability of 0.5% relative to the best fit. The data are consistent with antineutrino oscillations in the 0.01 < Delta m^2 < 1.0 eV^2 range and have some overlap with the evidence for antineutrino oscillations from the Liquid Scintillator Neutrino Detector." ... "The neutrino mode running also shows an excess at low energy of 162.0+-47.8 events (3.4 sigma), but the energy distribution of the excess is marginally compatible with a simple two neutrino oscillation formalism."

    Excerpt from the abstract of the 2010 anti-nue appearence paper (using an anti-numu beam):

    ... "An excess of 20.9+-14.0 events is observed in the energy range 475 MeV< EnuQE < 1250 MeV, which when constrained by the observed anti-numu events, has a probability for consistency with the background-only hypothesis of 0.5%. On the other hand, fitting for antinumu->antinue oscillations, the best fit point has a chi^2 probability of 8.7%. The data are consistent with antinumu->antinue oscillations in the 1.0 eV^2 Delta m^2 range and with the evidence for antineutrino oscillations from the Liquid Scintillator Neutrino Detector at Los Alamos National Laboratory."

    The MiniBooNE Collaboration
    Phys. Rev. Lett. 105, 181801 (2010)

    Excerpt from the abstract of the First Results paper (using a numu beam):

    ..."With two largely independent analyses, we observe no significant excess of events above background for reconstructed neutrino energies above 475 MeV. The data are consistent with no oscillations within a two neutrino appearance-only oscillation model."
