“…The average of the total π ± , independent of if a neutrino was produced or not, distributions were used for the π 0 prediction because of the tuning of BooNEG4Beam's π ± distributions. Taking the average of π + and π − is consistent with the expected π 0 distribution [85,86]. For off-target 90% of the total pions are generated in the steel beam dump.…”

This work would not have been completed without the help and support of several people. My wife, Holly, has been supportive throughout the entire process, while my children, David and Samuel, have been a huge motivation, always ready to entertain me during much needed breaks. The teaching and encouragement I received while under the leadership of my professors at Abilene Christian University formed the bedrock of my success in graduate school. Thank you. I am thankful Rex Tayloe took a chance on me: helped me get into Indiana University, was willing to be my advisor, and allowed my work schedule to be flexible once my children were born. Rex, Robert Cooper, and Lance Garrison helped me get my feet wet at IU and tought me how to work in/with a small collaboration. Rex, Robert, and Richard Van de Water encouraged me to make this analysis my own, not adhearing to what others had invision the analysis would be. I am thankful for their guidence and many productive conversations. I am thankful for Ranjan Dharmapalan's hard work in getting this analysis started, as an extension to his thesis, and helping me get up to speed. Much apparition goes out to Zarko Pavlovic in his continue work on the MiniBooNE computers. None of the current MiniBooNE analyses can be done without his hard work. This analysis is an accumulation of over a decade of work by a large number of people: the MiniBooNE collaboration, Fermilab Accelerator Division, and the neutrino group at Los Alamos to name a few. Their work in building/understanding the Booster Neutrino Beamline and MiniBooNE detector for the oscillation and cross section analyses allowed this analysis to be completed. I am thankful for collaborators like Byron Roe, Bill Louis, and Mike Shaevitz who still contribute and phone-in to detailed analyses meetings. This work could not have been completed with out the efforts of Patrick deNiverville iv and Brian Batell. I am so thankful for their work in developing the dark matter generator and being willing to answer my questions. v Remington Tyler Thornton SEARCH FOR LIGHT DARK MATTER PRODUCED IN A PROTON BEAM DUMP Cosmological observations indicate that our universe contains dark matter (DM), yet we have no measurements of its microscopic properties. Whereas the gravitational interaction of DM is well understood, its interaction with the Standard Model is not. Direct detection experiments, the current standard, search for a nuclear recoil interaction and have a low-mass sensitivity edge of order 1 GeV. A path to detect DM with mass below 1 GeV is the use of accelerators producing boosted low-mass DM. Using neutrino detectors to search for low-mass DM is logical due to the similarity of the DM and neutrino signatures in the detector. The MiniBooNE experiment, located at Fermilab on the Booster Neutrino Beamline, has produced the first proton beam-dump light DM search results. Using dark matter scattering from nucleons 90% confidence limits were set over a large parameter space and, to allow tests of other theories, a model independent DM r...

“…Table II gives the total number of π ± per POT as well as the breakdown by material in the beam line for both off-target and neutrino running simulated by BooNEG4Beam. The simulated π 0 distribution was chosen as the average of the π + and π − distributions which has been shown to be in good agreement with actual π 0 distributions [42][43][44]. Neutrino-mode charged- pions are generated evenly in beryllium, steel, and concrete.…”

A search for sub-GeV dark matter produced from collisions of the Fermilab 8 GeV Booster protons with a steel beam dump was performed by the MiniBooNE-DM Collaboration using data from 1.86 × 10 20 protons on target in a dedicated run. The MiniBooNE detector, consisting of 818 tons of mineral oil and located 490 meters downstream of the beam dump, is sensitive to a variety of dark matter initiated scattering reactions. Three dark matter interactions are considered for this analysis: elastic scattering off nucleons, inelastic neutral pion production, and elastic scattering off electrons. Multiple data sets were used to constrain flux and systematic errors, and time-of-flight information was employed to increase sensitivity to higher dark matter masses. No excess from the background predictions was observed, and 90% confidence level limits were set on the vector portal and leptophobic dark matter models. New parameter space is excluded in the vector portal dark matter model with a dark matter mass between 5 and 50 MeV c −2 . The reduced neutrino flux allowed to test if the MiniBooNE neutrino excess scales with the production of neutrinos. No excess of neutrino oscillation events were measured ruling out models that scale solely by number of protons on target independent of beam configuration at 4.6σ. arXiv:1807.06137v2 [hep-ex]

“…Alongside the charged mesons, FTNEs also produce the neutral pseudoscalar mesons π 0 and η. The π 0 is produced in quantities similar to those of the π þ and π − , while the η is produced at a rate suppressed by a factor of 20 to 30 [55,56]. The a and the γ 0 could be produced in radiative decays of the pseudoscalar mesons through the diagram shown in Fig.…”

Implications of the dark axion portal for the muon g−2 , B factories, fixed target neutrino experiments, and beam dumps

The dark axion portal is a recently introduced portal between the standard model and the dark sector. It connects both the dark photon and the axion (or axionlike particle) to the photon simultaneously through an anomaly triangle. While the vector portal and the axion portal have been popular venues to search for the dark photon and axion, respectively, the new portal provides new detection channels if they coexist. The dark axion portal is not a result of the simple combination of the two portals, and its value is not determined by the other portal values; it should be tested independently. In this paper, we discuss implications of the new portal for the leptonic g − 2, B factories, fixed target neutrino experiments and beam dumps. We provide the model-independent constraints on the axion-photon-dark photon coupling and discuss the sensitivities of the recently activated Belle-II experiment, which will play an important role in testing the new portal.
