Abstract: In this note the expected yields and the signal significances of Standard Model Higgsbosons produced in association with top quarks or Z or W bosons are estimated. The signatureof the two photons consistent with the Higgs mass is used to discriminate the signalfrom the background. A data set corresponding to 3000 fb􀀀1 recorded by an upgraded ATLASdetector running atps = 14 TeV with the high-luminosity LHC is assumed. Evidencefor WH and ZH production is expected as well as an observation with a significance of 8:2for the t¯tH production mode. The projected signal strength precision is between 17% and35%, depending on the production mode
