The associated Higgs production via Higgsstrahlung from a Z boson originating from gluon fusion is a loop-induced process with destructive interference between the triangle and box contributions at leading order. This makes the process a sensitive candidate to probe new beyond the standard model pyhsics (BSM). Therefore, comparing different Monte Carlo generators and investigating their differences is important for the development of physics analyses to access the gg→ZH process in data. This talk will present the comparison of 4 generators for the process gg→ZH with the Higgs boson decaying via the H→bb channel. The comparison is done using simulated CMS Run 2 datasets at √s = 13 TeV.
