Searches for Beyond Standard Model effects in rare B decays

The book describes the analysis of a rare flavor-changing neutral current process, B0→K π μ μ, focusing on the higher invariant mass range of the Kπ system. The research is based on data collected by the LHCb experiment in 2016, 2017, and 2018 (Run 2), when protons collided at a center-of-mass energy of 13 TeV (teraelectronvolts).The angular analysis of the final-state particles is performed using the method of moments. The main goal of the analysis is to search for so-called New Physics beyond the Standard Model.
