摘要：

The recent precision measurement of the W -boson mass reveals an exciting hint for the new physics as of the 3-3-1 model. We indicate that the 3-3-1 model con-tains distinct sources by itself that may cause the W-mass deviation, as measured, such as the tree-level Z -Z' mixing, the tree-level W -Y and Z -Z' -X mixings, as well as the non-degenerate gauge vector (X, Y) and new Higgs doublets. We point out that the gauge vector doublet negligibly contributes to this mass shift, whereas the rest of the effects with tree -level mixings governed by Z -Z' and new Higgs doublets are significant. A discussion of scalar sextet contributions is also given.
