(Received February 15, 1999)
The Editorial Committee of this journal wishes to acknowledge with regret that “BPS Spectra of Dyons in Four-Dimensional N=2 Supersymmetric Theories” by M. P. Singh and B. S. Rajput, which was published in Vol. 102 (1999), p. 843 of this journal, has been found to consist of work previously published in three papers, entitled “The Strong-Coupling Spectrum of the Seiberg-Witten Theory” [Nucl. Phys. B 469 (1996), 387] by F. Ferrari and A. Bilal and “Curves of Marginal Stability, Weak- and Strong-Coupling BPS Spectra in N=2 Supersymmetric QCD” [Nucl. Phys. B 480 (1996), 589] by A. Bilal and F. Ferrari, and “Charge Fractionization in N=2 Supersymmetric QCD” [Phys. Rev. Lett. 78 (1997), 795] by F. Ferrari.
Thus it should be noted that the above-mentioned paper by Singh and Rajput is not an original contribution.
For this reason, as of November 14, 2002, this article (including its abstract and references) has been removed from this site.
