A leptoquark and vector-like quark extended model for the simultaneous explanation of the boson mass and muon anomalies
arXiv:2205.02088 · doi:10.1088/1674-1137/ac9e4c
Abstract
The CDF collaboration recently announced a new measurement result of the boson mass, and it is in tension with the standard model (SM) prediction. In this paper, we explain this anomaly in the vector-like quark (VLQ) and leptoquark (LQ) extended model. In this model, both the VLQ and LQ have positive corrections to the boson mass. Moreover, it can also be a solution to the anomaly because of the chiral enhancements from top, , and quarks.
