 HL-LHC projections for signal and background yield measurements of the $H\to\gamma\gamma$ when the Higgs boson is produced in association with $t$ quarks, $W$ or $Z$ bosons In this note the expected yields and the signal significances of standard model Higgs bosons produced in association with top quarks or $Z$ or $W$ bosons are estimated.
