Top Physics Analysis for Future Circular Colliders Herbie

Top Physics Analysis for Future Circular Colliders Herbie Smith Advisor: Clement Helsens

Future Circular Collider (FCC) Study • Build a 80‐‐‐ 100 km tunnel to host new collider(s) • 1) pp‐‐‐collider (FCC ‐hh) defining infrastructure requirements • • ~8. 3 Tesla (LHC dipoles) ⇒ √s=42 Te. V pp in 100 km (Nb. Ti) ~16 Tesla ⇒√s=100 Te. V pp in 100 km (Nb. Sn 3) ~20 Tesla ⇒√s=100 Te. V pp in 80 km (HTS) Lead‐Lead collider possibility • 2) e+e collider (FCC‐ee) as potential intermediate step • Tera‐Z, Oku‐W, Mega‐H, Mega‐Top • 3) p‐e (FCC‐he) option

Future Circular Collider (FCC) Study • One possibility would be to host the collider in the Geneva area • Strong support from CERN • Infrastructures already exists • Including injectors (LHC as injector? ) • Fits perfectly within the mountains

My Project - Top Physics at the FCC • FCC‐hh would be a top quark factory • Large statistics allow precise determination of top quark branching ratios and other properties of the top quark as probe to new physics • First step is to simulate Monte‐Carlos events by interfacing a number of programs (Mad. Graph 5, Pythia 8, Delphes, . . . ) and generate enough statistics to perform analysis • Simulations allow us to better understand what to expect from 100 Te. V top production • Use boosted top‐quark as a benchmark for detector design
