Accelerating LHC phenomenology with analytic one-loop amplitudes: A C++ interface to MCFM

Understand

The evaluation of one-loop matrix elements is one of the main bottlenecks in precision calculations for the high-luminosity phase of the Large Hadron Collider.

• To alleviate this problem, a new C++ interface to the MCFM parton-level Monte Carlo is introduced, giving access to an extensive library of analytic results for one-loop amplitudes.
• Timing comparisons are presented for a large set of Standard Model processes.
• These are relevant for high-statistics event simulation in the context of experimental analyses and precision fixed-order computations.
