In the framework of the light-front quantum theory developed by Karmanov et al. an analysis of the experimental data on the tensor analyzing power of the nuclear fragmentation of relativistic deuterons with the large transverse momentum proton emission has been made. With Karmanov's wave function taken in system, in which z axis is directed along the deuteron beam, we have managed to explain the existing data without invoking additional to nucleons degrees of freedom.
