The main limitation encountered is the effect of the beam-beam long range (BBLR) interaction which limits the beam lifetime at collision and is well correlated with the minimum dynamic aperture (DA), as shown by measurements in the LHC. Thereby, multi-parametric DA simulations are used as a guide in order to define the collider settings and beam parameters through the LHC run. The same approach is used for validating the operational HL-LHC scenario and improving the beam performance at collision. Recent studies on the impact of tune modulation to the collider lifetime are briefly described. Finally, the potential of BBLR compensation in the HL-LHC era is evaluated through simulations and LHC machine studies. PB - JACoW Publishing CP - Geneva, Switzerland ER -
