Novel effects of the W-boson mass shift in the 3-3-1 model

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 contains 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 -...

Summary: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 contains 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.
