Measurement of proton-carbon forward scattering in a proof-of-principle test of the EMPHATIC spectrometer

The next generation of long-baseline neutrino experiments will be capable precision measurements oscillation parameters, neutrino-nucleus scattering, and unprecedented sensitivity to physics beyond the Standard Model. Reduced uncertainties in fluxes are necessary achieve high these future precise measurements. New hadron-nucleus interaction cross sections needed reduce fluxes. We report differential cross-section as a function scattering angle for proton-carbon interactions with single charged particle final state at beam momenta 20, 30, 120 GeV/c. These result test EMPHATIC, hadron-scattering hadron-production experiment. total, elastic inelastic cross-sections also extracted from data compared previous results can used current experiments, demonstrate feasibility by an upgraded EMPHATIC spectrometer.
