In the last decade, several matter-antimatter asymmetries have been observed in neutral B mesons in line with the expectations of the Standard Model of the weak interaction.  Direct \u003ci\u003eCP\u003c\/i\u003e violation is also expected in the decay rates of charged \u003ci\u003eB+ \u003c\/i\u003emesons versus that of \u003ci\u003eB-\u003c\/i\u003e mesons, though the greatest effects are present in a decay that occurs just twice in 10 million decays. Such rarity requires huge samples to study and this is exactly what the LHC, and its dedicated \u003ci\u003eB-\u003c\/i\u003ephysics experiment LHCb provide. This thesis presents an analysis of the first two years of LHCb data. The author describes the first observation of the rare decay, \u003ci\u003eB- → DK-, D → π-K+ \u003c\/i\u003eand the first observation of direct \u003ci\u003eCP\u003c\/i\u003e violation in this \u003ci\u003eB\u003c\/i\u003e decay. The work constitutes essential information on the experiment’s measurement of a fundamental parameter of the theory and stands as a benchmark against which subsequent analyses of this type will be compared.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783319376851\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783319010281\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783319376851","offer_id":39420485632093,"sku":"9783319376851","price":106.99,"currency_code":"EUR","in_stock":true},{"title":"Hardcover - 9783319010281","offer_id":40571042136157,"sku":"9783319010281","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/d097838c-3129-4e15-85cb-c4dbab758902.jpg?v=1775624545","url":"https:\/\/shop.autorenwelt.de\/products\/observation-of-cp-violation-in-b-dk-decays-von-paolo-gandini","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
