The E815 (NuTeV) neutrino experiment has performed a search for a 33. 9 MeV/c(2) weakly interacting neutral particle produced in pion decay. Such a particle may be responsible for an anomaly in the timing distribution of neutrino interactions in the KARMEN experiment. E815 has searched for this particle's decays in an instrumented decay region; no evidence for this particle was found. The search is sensitive to pion branching ratios as low as 10(-13).

Fermilab Upgrades and a Future Muon Program

Robert Bernstein

Fermilab Roadmap as described in the Fermilab Steering Group Report of August 2007 and of the Intensity Frontier science program described in the P5 report of May 2008. The primary elements of that research program to be supported by Project X include: (1) A neutrino beam for long baseline neutrino oscillation experiments. A new 2 megawatt proton source with proton energies between 50 and 120 GeV would produce intense neutrino beams, directed toward a large detector located in a distant underground laboratory. (2) Kaon and muon based precision experiments running simultaneously with the neutrino program. These could include a world leading muon-to-electron conversion experiment and world leading rare kaon decay experiments. (3) A path toward a muon source for a possible future neutrino factory and, potentially, a muon collider at the Energy Frontier. This path requires that the new proton source have significant upgrade potential beyond the initial uses. This paper suggests that an implementation of Project X based on a CW linac can be part of a continuous synergistic transition from a muon physics program in the 'Booster era' to the Neutrino Factory and Muon Collider. It then describes a possible staging of the planned muon experiments and of Project X to provide a graceful transition from the Intensity Frontier to the Energy Frontier.

Reply to the Comment on "A Precise Determination of Electroweak Parameters in Neutrino-Nucleon Scattering"

In a recent comment, Miller and Thomas assert that differences in nuclear shadowing effects between neutrino neutral current (NC) and charged current (CC) interactions could explain the difference between NuTeV's measurement of the weak mixing angle and the prediction from other electroweak data. We argue that the proposed effect could have only a small impact on sin2thetaW derived from the Paschos-Wolfenstein R- and that such an effect is strongly disfavored by the neutrino and anti-neutrino NC-to-CC cross-section ratios also measured by NuTeV.

Measurements of F2, xF3nu-xF3nub from CCFR neutrino-Fe and antineutrino-Fe data in a model independent way

arXiv (Cornell University) (2000)

A. Bodek U. K. Yang T. Adams A. Alton C. G. Arroyo

We report on the extraction of the structure functions F2 and Delta xF3 = xF3nu-xF3nub from CCFR neutrino-Fe and antineutrino-Fe differential cross sections. The extraction is performed in a physics model independent (PMI) way. This first measurement for Delta xF3 which is useful in testing models of heavy charm production, is higher than current theoretical predictions. The F2 (PMI) values measured in neutrino and muon scattering are in good agreement with the predictions of Next to Leading Order PDFs (using massive charm production schemes), thus resolving the long-standing discrepancy between the two sets of data.

Observation of seasonal variation of atmospheric multiple-muon events in the NOvA Near Detector

Physical review. D/Physical review. D. (2019)

M. A. Acero P. Adamson L. Aliaga T. Alion V. Allakhverdian

Using two years of data from the NOvA Near Detector at Fermilab, we report a seasonal variation of cosmic ray induced multiple-muon event rates which has an opposite phase to the seasonal variation in the atmospheric temperature. The strength of the seasonal multipl$ increase as a function of the muon multiplicity. However, no significant dependence of the strength of the seasonal variation of the multiple-muon variation is seen as a function of the muon zenith angle, or the spatial or angular separation between the correlated muons.
