A measurement is reported of the weak-phase γ, which is a fundamental parameter of the Standard Model and can be regarded as quantifying the amount of CP violation that is allowed by the theory. The parameter is measured through a determination of b-meson decays collected by the LHCb experiment at CERN. The b-mesons are reconstructed in a decay to a charm meson and a pion or a kaon, and the charm meson is itself reconstructed in one of two four-body final states (KKππ or ππππ). This is the first time these decay modes have been used in a γ measurement, which is itself a notable achievement of the thesis study. In order to interpret the measured observables in a theoretically clean manner, it is necessary to have knowledge of the dynamics of the charm-hadron decays. This knowledge is obtained from a study of charm-meson pair production in e+e- collisions at the psi(3770) resonance, using data collected by the BESIII experiment in Beijing. The quantum-correlations present in these decays give unique access to the required information, which is then imported back into the LHCb measurement. The precision obtained on γ is competitive with the most sensitive individual measurements so far performed of this parameter in other decay modes.\u003c\/span\u003e\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 2026-02-13\u003c\/p\u003e \u003cp\u003eFormat: Hardcover\u003c\/p\u003e \u003cp\u003eISBN-13: 9783032044808\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-3-032-04481-5\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 186\u003c\/p\u003e ","brand":"Springer Nature Switzerland","offers":[{"title":"Default Title","offer_id":44341323301004,"sku":"9783032044808","price":152.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783032044808.jpg?v=1773280578","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9783032044808","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
