As for the bremsstrahlung production, the case of relatively light quark mass,m q<15 GeV, has been investigated at PETRA-PEP energies byGaemers andGounaris (8)K. J. F. Gaemers andG. J. Gounaris:.

For the process (2.3), the results of Dicus and Willenbrock (6)D. A. Dicus andS. S. D. Willenbrock: do not agree with the ones of Jones and Petcov (5), quantitatively. Therefore, we analyse again the process (2.4), at √s=140, 170, 180 GeV, since the process (2.4) for these energies is studied by both authors. Our numerical results are concordant with ones byDicus andWillenbrok rather thanJones andPetcov, thus we support the former conclusion.
