Estudo da produção de quarks top na evaporação de buracos negros no LHC e FCC

Abstract

The Standard Model describes the three quantum field theories for electromagnetic, strong, and weak interactions among particles. The treatment of gravitational interactions at the quantum level remains an open question, which has motivated the proposition of various models for physics beyond the Standard Model based on the existence of extra spatial dimensions. In these models, the creation of black holes from the collision between two particles in hadronic colliders become possible. In this dissertation, we consider the model proposed by Arkani-Hamed, Dimopoulos, and Dvali (ADD model), which proposes the existence of large compactified extra dimensions, and investigate the creation and evaporation of black holes in proton-proton collisions at the Large Hadron Collider (LHC) and the Future Circular Collider (FCC). In particular, we estimate the production of top quarks from black hole evaporation using the Monte Carlo generator BLACKMAX and compare the associated predictions with those obtained with the PYTHIA generator for production via strong interaction. Results are presented for different values of the number of extra dimensions, Planck scale, and black hole mass.
