In this talk, I will present recent work aiming to improve theoretical predictions for the associated production of a top pair and a Higgs boson and top pair and a W or Z boson at the Large Hadron Collider. In particular, we derived formulas which allow us to resum to all orders in the QCD coupling constant large logarithmic corrections arising from soft gluon emission. An in-house parton level Monte Carlo code for the evaluation of these corrections was developed and employed to evaluate the total cross section and several differential distributions for these processes to NLO+NNLL accuracy.
