We present a Monte Carlo analysis of a Higgs Boson decaying into two bottom quarks produced from electron-positron collisions at 240 GeV center-of-mass energy in the context of the Future Circular Collider (FCC) feasibility study. The Higgs boson decay to two bottom quarks is the most copious Higgs decay and its measurement will allow for the most precise determination of the Higgs couplings...
The FCC-ee would facilitate the search for the rare decay of $H \rightarrow Z + \gamma$ with greater precision. We present a feasibility study of the analysis in the Higgsstrahlung production channel, where the Higgs decays further into the Z and $\gamma$. The events are produced via Monte Carlo generators at a center-of-mass energy of 240 GeV and luminosity of 150 $ab^-1$ and the detector...
The Future Circular Collider (FCC) plans to measure the Z parameters at center-of-mass energies $$ \sqrt{s} \approx m_Z $$ via measurements of the dimuon cross section and forward-backward asymmetries. We produce a numerical model for the Z –> μ+μ- decay with a Monte Carlo simulation to make predictions. We replicate the measurements performed with the L3 detector in the years 1993–95 to...
We investigate qualitatively the relative performance of various Monte Carlo event generators (including Pythia8, and Whizard3) for generating the two-photon back ground in the leptonic and hadronic final states at the FCC-ee. We consider e+e− interactions at the Z pole, where the two-photon background is a non-negligible background for various electroweak precision analyses such as the muon...
The proposed FCC-ee collider will improve electroweak precision measurements by orders-of-magnitude, producing new measurements and potentially revealing inconsistencies within the Standard Model. In our work, we investigate tau polarization precision measurements in order to project finer uncertainties on fundamental SM parameters, including the weak mixing angle. We perform a realistic Monte...
The W boson mass, an important parameter in the Standard Model, has a current measured value of 80.379 GeV with an uncertainty of 12 MeV. At FCC-ee, the expected precision should be reduced to below the 1 MeV level. A Monte-Carlo study is performed using the FCC-ee analysis framework through two decay channels of the W bosons (hadronic and semi-leptonic) at 180 GeV center-of-mass energy to...
