  The 4-dimensional model with topological mass generation that has recently
been presented by Dvali, Jackiw and Pi [G. Dvali, R. Jackiw, and S.-Y. Pi,
Phys. Rev. Lett. 96, 081602 (2006), hep-th/0610228] is generalized to any even
number of dimensions. As in the 4-dimensional model, the 2n-dimensional model
describes a mass-generation phenomenon due to the presence of the chiral
anomaly. In addition to this model, new 2n-dimensional models with topological
mass generation are proposed, in which a Stueckelberg-type mass term plays a
crucial role in the mass generation. The mass generation of a pseudoscalar
field such as the eta-prime meson is discussed within this framework.
