One-Loop Calculations with BlackHat
C. F. Berger, Z. Bern, L. J. Dixon +5
We describe BlackHat, an automated C++ program for calculating one-loop amplitudes, and the techniques used in its construction. These include the unitarity method and on-shell rec…
The Quirky Collider Signals of Folded Supersymmetry
Gustavo Burdman, Z. Chacko, Hock-Seng Goh +2
We investigate the collider signals associated with scalar quirks ("squirks") in folded supersymmetric models. As opposed to regular superpartners in supersymmetric models these pa…
Examination of Flavor Symmetry in Decays
Cheng-Wei Chiang, Michael Gronau, Jonathan L. Rosner
We study a relation between the weak phase and the rates and CP asymmetries of several decays of , , and , emphasizing the impact of the latter measurement…
The Baryon Anomaly: Evidence for Color Transparency and Direct Hadron Production at RHIC
Stanley J. Brodsky, Anne Sickles
We show that the QCD color transparency of higher-twist contributions to inclusive hadroproduction cross sections, where baryons are produced directly in a short-distance subproces…
Light-Front Dynamics and AdS/QCD Correspondence: Gravitational Form Factors of Composite Hadrons
Stanley J. Brodsky, Guy F. de Teramond
Light-front holography is a remarkable feature of the AdS/CFT correspondence between gravity in AdS space and conformal field theories in physical space-time; it allows string mode…
An Automated Implementation of On-Shell Methods for One-Loop Amplitudes
C. F. Berger, Z. Bern, L. J. Dixon +5
We present the first results from BlackHat, an automated C++ program for calculating one-loop amplitudes. The program implements the unitarity method and on-shell recursion to cons…
