Search for heavy, long-lived particles that decay to photons in ppbar collisions at sqrt(s)=1.96 tev (2009-06-02)This dissertation presents the results of the first search for heavy, neutral, longlived particles that decay to photons at a hadron collider. We use a sample of +jet+missing transverse energy events in p¯p collisions at ...

(2016-05-26)In this work, we examine properties of quantum chromodynamics (QCD) at moderate temperatures and density. These conditions are reached in the later stages of ultra-relativistic heavy-ion collisions after the matter has ...
