“…Their published result [13] confirmed the previous observations from IMB and Kamioka and came at a time when disappearance theories were gaining momentum as an explanation for both the solar neutrino problem and the atmospheric neutrino anomaly. A thorough review of the anomaly is given in Reference [14].…”

Aaron Michael McGowan 333 wordsObservation of deficit in NuMI neutrino-induced rock and non-fiducial muons in MINOS Far Detector and measurement of neutrino oscillation parameters Marvin pushed me quickly through the graduate curriculum and sent me to Argonne, where I could be close to the daily operations of our experiment. Most of all, Marvin understood my plight of falling in love with my best friend from college, who went on to medical school in Manhattan. He made our long-distance relationship possible, and has rendered me nearly as much relationship advice as guidance for my analysis.My advisor away from the university halls, Maury Goodman, for the painstaking (painful?) editing of this document and for daily filling the gap that exists in public transportation between Fermilab and Argonne. Maury helped me to boil problems down to simple arguments, making it clear to me when I was fixated on a second-order effect. I also thank Sharon Goodman, for providing delicious home-cooked dinners on occasion as a break from the weary road of ramen noodles.All MINOS collaborators who came before me. I came into MINOS roughly twelve years after it formed. It goes without saying that none of the work in this dissertation would be possible without the years of dedicated service that have gone into this experiment by the past and present members of our collaboration.The mine crew: Bill Miller, Jerry Meier, Dave Saranen, Eileen Amos, Doug Wiermaa, Brian Anderson, and Curt Lerol, for introducing me to the way of life in the north country, half a mile underground.The Minnesota Department of Natural Resources and the Soudan Underground Mine i State Park for hosting our experiment. Pete Border, Leon Mualem, and Keith Ruddick, for introducing me to the clumsy art of experimentation and preparing me for research in a no-nonsense way.The neutrino group at Argonne: Juergen Reichenbacher, Tom Fields, Dave Ayres, Dave Reyna, and Phil Schreiner, for suggestions for this analysis and providing feedback on my presentations.My friends in Dorm 6: Dan, Allison, Jim, and Rebekah, for introducing me to karaoke night and more free food than a grad student could wish for. I've never seen so many ribs cooked in one kitchen. Thanks for the euchre and hospitality.All of Young MINOS, for the support, sounding board, and several evenings spent in diversion from the life that is graduate school.My classmates from the Twin Cities: Pearl Sandick, Matt Fritts, Scott Thaller, Marie Lopez del Puerto, Charlie Blackwell, Beth Lusczek, Jason Haupt, Abe DeBenedetti, Hannes Hubmayr, Mun Chan, Brian Batell, and Nate Lindquist, for trips to the Village Wok, for bearing with me the huge burritos late at night, and for Poor Man's Black Velvet parties. You guys got me through two years of endless problem sets.The older, wiser Minnesota students who helped me along the path: Ben Speakman, Emily Maher, Sujeewa Kumaratunga, Dipu Rahman, Jeremy Gogos, Bernie Becker, and Erik Beall.My friends from AEP, Pete, Tom, Erin, Punit, Sergei. I kept the crafts in line, it was ...

“…The reconstruction accuracy is pretty poor below 1 GeV. To take the measurement error into account, the neutrino direction generated is smeared [25,26] according to the law 40 o / (E ν to get the outgoing lepton direction, while for the lepton momentum a flat random generation between 0.25×E ν and E ν is used. The S.K.…”

The first AMS flight in June 1998 on board of the space shuttle Discovery at an altitude of approximately 380 km unveiled unexpected features of the cosmic rays spectra below the Earth geomagnetic cut-off. In addition to a secondary flux of particles at all latitude, a ring of high energy particles (up to 6 GeV) and an anomalous ratio e+/e-as high as 4 was observed near the geomagnetic equator. This paper describes a simulation of the interaction of primary cosmic rays with atmosphere in which the effect of the Earth magnetic field is included. Using the GEANT3 package for the tracking of particles with the GFLUKA associated package for the physics of interactions, this simulation reproduces quite well the AMS experimental results and the CAPRICE muon data at ground level. The predictions of this model for the flux of atmospheric neutrino are compared with the Super-Kamiokande results and with the results of other atmospheric neutrino models.

“…The atmospheric ν e flux, observed by SuperKamiokande [17], does not show any distance or energy dependent suppression. The observed angular and energy dependence agrees with the expected one.…”

Neutrino suppression and extra dimensions: A minimal model

We study flavor neutrinos confined to our four-dimensional world coupled to one "bulk" state, i.e., a Kaluza-Klein tower. We discuss the spatial development of the neutrino disappearance, the possibility of resurgence and the effective flavor transitions induced in this mechanism. We show that even a simple model can produce an energy independent suppression at large distances, and relate this to experimental data.
