Description
The Standard Model (SM) of particle physics describes elementary particles and their interactions, but may be an effective theory incorporated into a more general framework at higher energies. Searching for physics beyond the SM is a key goal, pursued through direct high-energy searches and precision indirect measurements.
The Belle II experiment, situated at KEK, Japan, probes the SM by analysing meson and lepton decays from electron-positron collisions at 10.58 GeV energy, focusing on indirect search of non-SM physics. One such decay, ( B^+ \to K^+ \tau^+ \tau^- ), is sensitive for our search but challenging to detect due to the presence of neutrinos in the final states. In this project, we will analyse Belle II simulation data to search for this decay and set up the framework to reject the $10^9$ times background events compared to the signal ( B^+ \to K^+ \tau^+ \tau^- ) events. Students will learn data analysis, Monte Carlo (MC) simulation, machine learning techniques, and statistical methods for high-energy physics. Prior knowledge of Python programming is required.
