MiniBooNE is the Booster Neutrino Experiment located at Fermilab in Batavia, IL. The goal of the experiment is to definitively test the neutrino oscillation signal reported by the LSND experiment at Los Alamos. Secondary hadron production rates are important for calculating the neutrino flux in the MiniBooNE detector, and the goal of this effort is to reduce the uncertainties in these rates to a few percent.

HARP is a hadron production experiment at CERN in Geneva, Switzerland, designed to measure hadron production cross sections as a function of target material and beam energy. These cross sections are important for neutrino factory design efforts and atmospheric neutrino flux calculations in addition to neutrino fluxes for MiniBooNE.
