Abstract
Rare decay modes of the newly discovered standard-model-like Higgs boson may test the flavor-changing couplings in the leptoquark sector through the process . Motivated by the recently reported excess in LHC data from the CMS detector, we found that a predicted branching fraction Br() at the level of 1% is possible even though the coupling parameters are subjected to the stringent constraint from the null observation of , where the destructive cancellation among amplitudes is achievable by fine-tuning.
