Measurement of |vcb| Using the Semileptonic Decay Λb → Λcμνμ
… measurement of the quark-mixing parameter |Vcb| using the exclusive decay Λ0b→ Λ+c μ−νμ is presented. A sample of Λb semileptonic decays is provided by √s = 13TeV proton-proton collisions collected by the LHCb detector in 2017. Λ0b → Λ+c μ−νμX decays are identified from muon tracks, combined …

Reconstruction of B- --> D*° e- nu Decays and Determination of |Vcb|
… following two parameters of dGamma/dw: (i) F(1)|Vcb|, the product between F at zero D*°-recoil and the Quark mixing parameter |Vcb|; (ii) rho^2, a parameter of the form factor F(w). The former parameter scales the height of dGamma/dw and rho^2 varies the shape of it. The determined values of …

Direct current hybrid vacuum breaker
… arc, this thesis uses a vacuum circuit breaker (VCB) as the main breaker to investigate arc effects on interruption performance, when employing a forced current commutation method. The vacuum arc characteristics are detailed, thereby giving the VCB operation understanding needed. The VCB opening …

Synthesis of Non-Steroidal Estrogen Receptor Proteolysis Targeting Chimeric Molecules (Protacs)
… proline residue for recognition by the VCB E3 ligase. The synthesis of a tetrahydrofuran-based hydroxyproline analog was attempted with encouraging results. Upon completion of the synthesis, this analog can be attached to an ER ligand in place of the HIF-1alpha destruction sequence and …

Measurement and Interpretation of Moments of the Combined Hadronic Mass and Energy Spectrum in Inclusive Semileptonic B-meson Decays
This thesis presents first measurements of moments of the hadronic n_X^2 distribution measured in inclusive semileptonic decays of B mesons to final states containing a charm quark, B->Xc l nu. The variable n_X^2 is a combination of the invariant mass of the charmed meson m_X, its energy in the …
