摘要：
Searches for the decay of the Higgs boson in a pair of charm quarks (H -+ cc over bar ) were carried out by the CMS and ATLAS experiments with data collected during the Run -2 of the LHC in proton -proton collisions. The most stringent upper limit on the signal strength was set by the CMS Collaboration in the VH production mode, with the Higgs boson produced in association with a leptonically decaying vector boson (W or Z). The observed upper limit on sigma (V H)B(H -+ cc over bar ) is 14 times the standard model prediction. During Run -3, tighter constraints could be established by extending the search to other production mechanisms of the Higgs boson, like the vector boson fusion. The search for H -+ cc over bar performed by CMS with Run -2 data is described in this work.
