• #### Direct Photon Production With Eﬀective Field Theory ﻿

(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 ﻿

(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 ﻿

(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 ﻿

(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 ...
