Relativistic description of polarized-deuteron fragmentation accompanied by the emission of high-transverse-momentum protons

Available experimental data on the tensor analyzing power for nuclear relativistic-deuteron fragmentation accompanied by the emission of high-transverse-momentum protons are analyzed within light-front quantum mechanics. It is shown that, in contrast to calculations with standard wave functions, calculations employing the relativistic deuteron wave function obtained by V.A. Karmanov and his coauthors on the basis of light-front dynamics can explain the entire body of data without resort to additional degrees of freedom.
