$W$-boson Mass Anomaly from High-Dimensional Scalar Multiplets
Abstract
In light of the recently discovered -boson mass anomaly by the CDF Collaboration, we discuss two distinct mechanisms that could possibly explain this anomaly through the introduction of high-dimensional scalar multiplets. The first mechanism is the tree-level -boson mass correction induced by the vacuum expectation values of one or more scalar multiplets with odd dimensions of and zero hypercharge of in order to avoid the strong constraint from measurements of the -boson mass. The second mechanism is to consider the one-loop level -boson mass correction from a complex multiplet. In particular, we focus on the case with an additional scalar octuplet with . As a result, we find that both mechanisms can explain the -boson mass anomaly without violating any other theoretical or experimental constraints.
