Description

The 2015 LHC run has shown the beauty of having weaker beam-beam effects with respect to 2012 physics run. The 2015 set-up has been defined to allow Landau octupole and chromaticity to be powered at maximum currents to fight coherent instabilities. Quantitative studies of the impact of reduced crossing angles on the beam and luminosity lifetimes have been used to compare to expectations from Dynamical Aperture studies. Possible scenarios for the 2016 RUN will be presented highlighting the beam-beam limits expected from long range and head-on.
