Study Of Neutral Hadron Production In A High Intensity Particle Physics Experiment., Jake W. Berg

Electronic Theses and Dissertations

In this dissertation I present independent measurements of the multiplicities, R, of π⁰ and η mesons produced in annihilation interactions of electrons and positrons at a center-of-mass energy of 10.54 GeV. Data were collected using the BaBar detector at the PEP-II storage rings located at the SLAC National Accelerator Laboratory in Menlo Park, California. Both mesons have a decay mode to two photons, which is used to identify them and measure their production per event. I find R(π⁰) = 2.8±0.3 per event and R(η) = 0.25±0.03 per event. I also present my contributions to …
