“…The last two decades have witnessed important advances in flavour physics and in particular heavy-meson decays. From the first observation of a B meson by the CLEO Collaboration in 1981 at the Cornell Electron Storage Ring [1] (and their ongoing D-meson research program) to the dedicated B-physics facilities at SLAC in California and KEK in Japan, much progress has been made. Of course, while B physics is the main focus of the Collaborations Belle at KEK and BaBar at SLAC, and of the CDF experiment at Fermilab, considerable efforts have also been devoted to studies of D-meson decays, charmonium and τ physics.…”

We review theoretical approaches to form factors that arise in heavy-meson decays and are hadronic expressions of non-perturbative QCD. After motivating their origin in QCD factorisation, we retrace their evolution from quark-model calculations to non-perturbative QCD techniques with an emphasis on formulations of truncated heavy-light amplitudes based upon Dyson-Schwinger equations. We compare model predictions exemplarily for the F B→π (q 2 ) transition form factor and discuss new results for the gD * Dπ coupling in the hadronic D * decay.

“…Since the discovery of the J=Ψ and ϒ resonances in the 1970s, heavy meson physics (including the physics of charmonia [1,2], bottomonia [3,4], open-charm [5,6], and open-bottom [7][8][9] mesons) has been extensively studied and still is the subject of intensive theoretical and experimental research [10,11]. Recently, both the charmonium and bottomonium spectra have been enriched by the discovery of new particles [10,11] [10,16], Dð2740Þ 0 [10,17], and B J ð5970Þ 0 [10,18].…”

“…The Υ is a bound state with a net bottom quantum number of zero, and thus an example of "hidden beauty", in analogy to the J/ψ meson, the cc "hidden charm" bound state discovered three years earlier. The first B meson with non-zero bottom quantum number was observed shortly thereafter in 1981 [20]. The first observation of the heavy gauge bosons W ± and Z 0 occurred in 1983 [21].…”

In this dissertation, we present the results of a time-dependent angular analysis of B s → J/ψφ decays performed with the use of initial-state flavor tagging. CP violation is observed in this mode through the interference of decay without net mixing and decay with net mixing, that is, B s → J/ψφ and B s → B s → J/ψφ. The timedependent angular analysis is used to extract the decay widths of the heavy and light B s eigenstates and the difference between these decay widths ∆Γ s ≡ Γ L s − Γ H s . Initial-state flavor tagging is used to determine the matter-antimatter content of the B s mesons at production time. We combine flavor tagging with the angular analysis, which statistically determines the contributions of the CP-even and CPodd components at decay time, to measure the CP-violating phase β s . The phase β s is expressed in terms of elements of the Cabibbo-Kobayashi-Maskawa matrix as β s ≡ arg (−V ts V * tb /V cs V * cb ), and is predicted by the Standard Model to be close to zero, β SM s = 0.02. In the measurement of ∆Γ s , we use a dataset corresponding to 1.7 fb −1 of luminosity, collected at the CDF experiment from proton-antiproton collisions at a center of mass energy √ s = 1.96 TeV. In the measurement of β s , we use a dataset corresponding to 1.3 fb −1 of collected luminosity. We measure ∆Γ s = (0.071 +0.064 −0.059 ± 0.007) ps −1 using the time-dependent angular analysis. Combining the angular analysis with flavor-tagging, we find that assuming the Standard Model predictions of β s and ∆Γ s , the probability of a deviation as large as the level of the observed data is 33%. We obtain a suite of associated results which are discussed in detail in this dissertation alongside the main results.Thesis Supervisor: Christoph M.E. Paus Title: Associate Professor AcknowledgmentsExperimental particle physics is a fundamentally collaborative effort, and the work presented in these pages would not have been possible without the guidance, assistance, and support of my colleagues at MIT and at the CDF experiment. My time as a Ph.D. student was also made infinitely more enjoyable by the personal relationships I have been lucky to forge during these years.I am the eleventh student to have the privilege to call Christoph M.E. Paus his Ph.D. advisor. His intuition and skill as a physicist, his dedication, his indefatigability and leadership are all evident in the contributions he has made to our field. These qualities need not my reiteration; they form the natural basis for the admiration shared by all those who know him well. Eleven of us have been lucky to know the qualities that make Christoph stand out as an unmatched mentor and advisor. He manages to give his students generous support while simultaneously granting them the essential independence necessary to develop their own skills. He knew when to trust that my approach was the right one, or when to let me find out that it was the wrong one, and when to step in to correct my course. And finally, perhaps most importantly, he knew how to guide me through ch...
