Precision measurement of the CKM parameter sin(𝟮𝝱) with the LHCb experiment

, 2015
Die vorliegende Dissertation beschreibt eine zerfallszeitabhängige Messung von CP-Verletzung im Zerfall von B0- und Anti-B0-Mesonen in ihren gemeinsamen Endzustand J/ψ KS. Die Größe der Symmetrieverletzung in der Interferenz der Zerfalls- und Mischungs-Amplituden der B-Mesonen lässt sich durch die CP-Observablen S(J/ψ KS) und C(J/ψ KS) ausdrücken und ...

Complete O α s 2 $$ \mathcal{O}\left({\alpha}_s^2\right) $$ corrections to the leptonic invariant mass spectrum in b → X c l ν ¯ l $$ b\to {X}_cl{\overline{\nu}}_l $$ decay

Journal of High Energy Physics
In the determination of the Cabibbo-Kobayashi-Maskawa matrix element |V cb | from inclusive semileptonic B-meson decays, moments of the leptonic invariant mass spectrum constitute valuable observables.

Determining the CKM Parameter Vcd from nuN Charm Production

, 1997
The formalism for extracting the CKM parameter $V_{cd}$ from $νN$ production of charm is discussed in some detail. The various model assumptions needed are clearly pointed out. A direct determination from neutrino induced dimuon production requires $νN$ charm production data, $% νN$ charm hadronization data, and the semi-muonic branching ratios for ...

Inclusive semileptonic B s 0 $$ {B}_s^0 $$ meson decays at the LHC via a sum-of-exclusive modes technique: possibilities and prospects

Journal of High Energy Physics
We propose an approach for measuring the moments of the hadronic invariant mass distribution in semileptonic B s 0 $$ {B}_s^0 $$ meson decays using a sum-of-exclusive technique. Using the present and foreseen knowledge about exclusive semileptonic B s 0 $

Lattice calculations for B and K mixing

, 2006
The bag parameters and the decay constants of neutral B(s)and K mesons were among the non-perturbative hadronic inputs to the classical CKM Unitarity Triangle Analysis.

Exploiting perpendicular momentum distributions of semileptonic decays: B ¯ s 0 → D s + μ − ν ¯ $$ {\overline{B}}_s^0\to {D}_s^{+}{\mu}^{-}\overline{\nu} $$ as a case study

Journal of High Energy Physics
We derive the differential distribution of semileptonic decays with respect to the perpendicular momentum component of the final state hadron. The benefits and shortfalls arising from measurements of these distributions are discussed.

CKM physics at CDF [PDF]

, 2006
A precise knowledge of the CKM matrix elements is one of the primary goals of the CDF experiment. The Tevatron collider at Fermilab, operating at {radical}s = 1.96, collected 1 fb{sup -1} of data corresponding to a huge b{bar b} sample. In this paper the
