Bottomonium Spectroscopy at Belle: Studies of Radiative and Hadronic Transitions
The large constituent quark mass of bottomonium, the bottom quark/anti-quark bound state $(bbbar)$, affords a rich spectroscopy in which the perturbative (non-relativistic) limit of Quantum Chromodynamics may be theoretically described and experimentally investigated. The radial excitations of …

All Dressed Up And Ready To Go: A Tale Of Two Quarks.
… in heavy Quarkonia, specifically Charmonium and Bottomonium like states, is of great interest to modern particle physics. States like X(3872), Yb(10890), Zb(10610), and Zb(10650) have proven difficult to reconcile with the conventional quark model. However, analysis of diquark constituent masses …

Quarkonium Suppression in pPb Collisions at CMS and Timing Detectors for Future Collider Experiment
… in proton–ion collisions. In addition, bottomonium production has been studied through 𝚼(nS)/𝚼(1S) yield ratios, which exhibit suppression patterns consistent with those of the charmonium results, indicating that a similar final-state effect may be at play. These results indicate …

Heavy quark physics on the lattice with improved nonrelativistic actions
… heavy quark action, the spectrum of bottomonium is calculated and masses of several bottom baryons are predicted. In these computations, the light quarks are implemented with a domain wall action.

Suppressions and cascades : insights from gauge/gravity dualities
… qualitative features of my results may apply to bottomonium and charmonium mesons propagating in the strongly coupled QCD plasma. To aid further investigations of the effect of fundamental matter on hot gauge theory plasmas I find the non-extremal, localized D2/D6-brane solution in its linear …

Observation of upsilon suppression, search for long-lived particles, and observation of B0s → micro + micro-- at the LHC with the CMS experiment
… (PbPb) collisions. A detailed measurement of the bottomonium production will help to characterize the dense matter produced in heavy-ion collisions. The full spectroscopy of quarkonium states has been proposed as a possible thermometer for the QGP. The measurement reported in Chapter 3 is …

Third-order QCD corrections to heavy quark pair production near threshold
The measurement of the top quark mass is an important task at the future International Linear Collider. The most promising process is the top quark pair production in the threshold region. In this region the top quarks behave non-relativistically and a perturbative treatment using effective field …
