Beyond LHC: The future of particle physics (HL-LHC, FCC).

The data from the LHC will continue to advance our knowledge of the fundamental properties of matter, but several crucial questions that put in question the Standard Model will remain. To extend its capabilities the LHC will undergo a major upgrade to increase its instantaneous luminosity and collect up to $3 {ab^{-1}}$ (HL-LHC). An overview of the physics potential of the HL-LHC will be presented focusing on its unique strengths. Moreover, in 2020 CERN has started a feasibility study for the construction of Future Circular Colliders (FCC) in the Geneva region with a circumference of about $100 {km}$. An $e^{+}e^{-}$ collider (FCC-ee), covering the energy range from the $Z$ pole ({\sqrt$s$=90 ${GeV}$) up to the top pair production threshold ({\sqrt$s$=365 ${GeV}$) is the first step to collect incredible statistics of the heaviest particles of the SM. The ultimate goal would be a $pp$ collider (FCC-hh) reaching $100 {TeV}$ in the centre of mass. The FCC integrated project offers an incredible discovery potential with a careful mixture of precision measurements sensitive to very weak coupling or very heavy objects, and very high energies where the new heavy particle could be directly produced.
