    • Direct Photon Production With Effective Field Theory 

      Becher, Thomas; Schwartz, Matthew D (Springer Verlag, 2010)
      The production of hard photons in hadronic collisions is studied using Soft-Collinear Effective Theory (SCET). This is the first application of SCET to a physical, observable cross section involving energetic partons in ...
    • The Parsec‐Scale Accretion Disk in NGC 3393 

      Kondratko, Paul T.; Greenhill, Lincoln J.; Moran, James M. (American Astronomical Society, 2008)
      We present a Very Long Baseline Interferometry image of the water maser emission in the nuclear region of NGC 3393. The maser emission has a linear distribution oriented at a position angle of ~–34°, perpendicular to both ...
    • Pure Samples of Quark and Gluon Jets at the LHC 

      Gallicchio, Jason; Schwartz, Matthew D (Springer Verlag, 2011)
      Having pure samples of quark and gluon jets would greatly facilitate the study of jet properties and substructure, with many potential standard model and new physics applications. To this end, we consider multijet and ...
    • Resummation of Heavy Jet Mass and Comparison to LEP Data 

      Chen, Yang-Ting; Schwartz, Matthew D (Springer Verlag, 2010)
      The heavy jet mass distribution in e\(^+\)e\(^−\) collisions is computed to next-to-next-to-next-to leading logarithmic (N\(^3\)LL) and next-to-next-to leading fixed order accuracy (NNLO). The singular terms predicted from ...
    • Tidal Disruption of Stars by Supermassive Black Holes 

      Stone, Nicholas Chamberlain (2013-09-16)
      This thesis presents theoretical results on the tidal disruption of stars by supermassive black holes (SMBHs). The multiwavelength ares produced by tidal disruption events (TDEs) have supernova-like luminosities, and ...
