A measurement is reported of the weak-phase ?, 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 (KKpp or pppp). This is the first time these decay modes have been used in a ? 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 ? is competitive with the most sensitive individual measurements so far performed of this parameter in other decay modes.\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublication date:\u003c\/strong\u003e 13 February 2026\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePage count:\u003c\/strong\u003e 186\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e Height 235 mm; Width 155 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublisher:\u003c\/strong\u003e Springer Nature Switzerland AG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Hardback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISBN-13:\u003c\/strong\u003e 9783032044808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Martin Duy Tat","offers":[{"title":"Hardback","offer_id":50207310840058,"sku":"9783032044808","price":110.44,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0522\/4297\/2845\/files\/9783032044808.jpg?v=1788223619","url":"https:\/\/shulphink.com\/products\/model-independent-measurement-of-the-ckm-angle-y-in-b-h-h-p-p-dh-h-k-p-decays-at-lhcb-and-besiiii-9783032044808","provider":"Shulph Ink","version":"1.0","type":"link"}
