Radiative bottomonium spectroscopy at the [upsilon](2,3S) resonances at BaBar
Abstract/Contents
- Abstract
- The compact bound state consisting of a bottom and anti-bottom quark pair interacting via the strong nuclear force is called "bottomonium." A wealth of long-lived bottomonium states can be both experimentally produced and theoretically described, providing a unique tool to probe calculation techniques with experiment. Bottomonia with total angular momentum J = 1 and orbital angular momentum L = 0 at a variety of radial excitations n -- called [upsilon](nS) -- can be produced at electron-positron colliders. The BABAR experiment, located at the interaction point of such a collider (the PEP-II storage ring), has observed 122 million [upsilon](3S) and 100 million [upsilon](2S) decays. Some of these involve a transition to the bottomonium state [chi]bJ(nP) (L = 1 and J = (0, 1, 2)), emitting a photon, with subsequent transition to a lower [upsilon](nS), also emitting a photon. The final [upsilon](nS) can be identified through a decay to two muons. The dependence of the branching fractions and photon energies in this process on the spin state of the intermediate [chi]bJ(nP) is a key test of phenomenological models. To this end, this dissertation contains a nearly comprehensive study of these transitions with an emphasis on experimentally optimal discrimination between various models. This focus spurs innovative techniques that complement a large array of physics results, both presented in detail herein.
