*“Physics Opportunities at FCC"*

_Abstract_
In 2020 CERN started the Feasibility Study for the construction of 
Future Circular Colliders (FCC) in the Geneva region with a 
circumference of about 91 km. An electron-positron collider (FCC-ee), 
that would cover the energy range from the Z pole (and maybe below)  up 
to the top pair production threshold (and maybe above) is the possible 
first step for the collection of an unprecedented amount of Z, W, Higgs 
and top particles. The ultimate goal is a proton-proton collider 
(FCC-hh) at about 100 TeV, which could also be used for Heavy Ions 
collisions. The combination of these two machines, FCC-ee and FCC-hh, 
offers an incredible discovery potential, unique on the market, with a 
careful mixture of precision measurements sensitive to very weak 
coupling or very heavy objects, and very high energies where the new 
heavy particles could be directly produced.

*“Primordial Gravitational Waves from Cosmic Inflation "*

_Abstract_
In this talk, we explore the origins of primordial gravitational waves 
(GWs) from the early universe. We begin with an introduction to 
gravitational waves, their generation, and detection. We then discuss 
how quantum fluctuations during the cosmic inflation period produce 
primordial GWs, serving as a window into inflationary physics. We also 
cover graviton bremsstrahlung during reheating, where the decay of the 
inflaton field and particle interactions generate additional GWs. 
Finally, we examine GW production mechanisms during reheating, revealing 
insights into the universe's thermal history and energy scales.
