Abstract: We propose a new BRST operator for the B-twist of N = 2 Landau-Ginzburg (LG) models, It solves the problem of the fractional ghost numbers of Vafa's old BRST operator and shows how the model is obtained by gauge fixing a zero action, An essential role is played by the anti-BRST operator, which is given by one of the supersymmetries of the N = 2 algebra. Its presence is needed in proving that the model is indeed a topological field theory, The space of physical observables, defined by taking the anti-BRST cohomology in the BRST cohomology groups, is unchanged.
