  ABSTRACT: We have measured cross sections for forward neutron production from a variety of targets using proton beams from the Fermilab Main Injector. Measurements were performed for proton beam momenta of 58 GeV/c, 84 GeV/c, and 120 GeV/c. The cross section dependence on the atomic weight (A) of the targets was found to vary as $A^(alpha)$ where $\alpha$ is $0.46\pm0.06$ for a beam momentum of 58 GeV/c and 0.54$\pm$0.05 for 120 GeV/c. The cross sections show reasonable agreement with FLUKA and DPMJET Monte Carlos. Comparisons have also been made with the LAQGSM Monte Carlo.

  ABSTRACT: The two most recent and precise measurements of the charged kaon mass use X-rays from kaonic atoms and report uncertainties of 14 ppm and 22 ppm yet differ from each other by 122 ppm. We describe the possibility of an independent mass measurement using the measurement of Cherenkov light from a narrow-band beam of kaons, pions, and protons. This technique was demonstrated using data taken opportunistically by the Main Injector Particle Production experiment at Fermi National Accelerator Laboratory which recorded beams of protons, kaons, and pions ranging in momentum from +37 GeV/c to +63 GeV/c. The measured value is 491.3 +/- 1.7 MeV/c^2, which is within 1.4 sigma of the world average. An improvement of two orders of magnitude in precision would make this technique useful for resolving the ambiguity in the X-ray data and may be achievable in a dedicated experiment.

  ABSTRACT: We propose to measure hadronic particle production with excellent particle identification using primary and secondary beams from the Main Injector. The goals of the experiment are: to verify a general scaling law of hadronic fragmentation; to measure particle production off NuMI targets using 120 GeV/c protons with sufficient accuracy to predict the NuMI neutrino spectrum; and to collect a comprehensive data set that would have a profound impact on related physics issues, such as atmospheric neutrino flux estimates, neutrino factory design, and simulations of hadronic showers for highenergy colliders. This experiment could also form the basis for a long-term program in light-meson spectroscopy. i Contents 1 Executive Summary 1 2 Introduction 2 3 Physics Motivation 4 3.1 Scaling Law of Hadronic Fragmentation . . . . . . . . . . . . . . . . . . . . . 4 3.2 Systematic Errors in NuMI/MINOS Measurements of Neutrino Oscillation Parameters . . . . . . . . . . . . . . . . . . . . ....
