Comment on: "One loop renormalization of soliton quantum mass corrections in (1+1)-dimensional scalar field theory models" [Phys. Lett. B 542 (2002) 282]

We refute the claim that previous works on the one-loop quantum mass of solitons had incorrectly dropped a surface term from a partial integration. Rather, the paper quoted in the title contains a fallacious derivation with two compensating errors. We also remark that the phi(2)cos(2)ln(phi(2)) model considered in that paper does not have solitons at the quantum level because at two-loop order the degeneracy of the vacua is lifted. This may be remedied, however, by a supersymmetric extension. (C) 2002 Elsevier Science B.V. All rights reserved.
