Abstract
More than deviations from the standard model are observed in the angular observable of and muon . To resolve these anomalies, we extend the standard model by adding two leptoquarks. It is found that the signal strength of the diphoton Higgs decay can exhibit a significant deviation from unity and is within the data errors. Although puts severe bounds on some couplings, it is found that the excesses of and the muon can still be explained and accommodated to the measurement of in this model. In addition, the leptoquark effects can also explain the LHCb measurement of , which shows a deviation from the standard model prediction.
