摘要
The CDF collaboration recently announced a new measurement result for the W boson mass,and it is in tension with the standard model prediction.In this paper,we explain this anomaly in the vector-like quark(VLQ)(X,T,B)_(L,R)and leptoquark(LQ)S_(3)extended model.In this model,both the VLQ and LQ have positive corrections to the W boson mass.Moreover,it may be a solution to the(g-2)_(μ)anomaly because of the chiral enhancements from top,T,and B quarks.
