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 number density of a charged relic
Carola F. Berger, Laura Covi, Sabine Kraml +1
We investigate scenarios in which a charged, long-lived scalar particle decouples from the primordial plasma in the Early Universe. We compute the number density at time of freeze-…

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…
