Extensive high precision studies of proton deuteron breakup reactions at COSY

Abstract

We plan to measure the spin dependence of proton deuteron breakup at 30 and 49 MeV proton beam energy where previous measurements are few and limited.The physics objective is to test the predictive power of the chiral effective field theory in the three nucleon continuum by measuring analyzing powers and double spin observables with high precision over large areas of phase space at relevant energies for the theoretical interpretation.The experiment will be done at a newly installed and commissioned low-β section and interaction point in the COSY ring utilizing the PAX Multipurpose Detection System that is presently in the design stage.
