In the second paragraph of Section 2 of our Letter [1], we have incorrectly presented that all the standard model (SM) particles are

(+,+) under the discrete symmetry Z 2 × Z 2 . This should be changed to all SM bosons (photon, Higgs, W ± , Z ) are (+,+) and all SM fermions are (−,−) under Z 2 × Z 2 . This change does not affect either any other part of this Letter [1], or physical conclusions. In the Acknowledgements, “(KRF-2006-003-C00069)” should be changed to “(KRF-2006-331-C00069)”.
