The evaluation of one-loop matrix elements poses a challenge for precision calculations at the Large Hadron Collider, but a new C++ interface has been introduced to access an extensive library of analytic results. Timing comparisons for Standard Model processes have been presented, which are important for high-statistics event simulation and precision fixed-order computations.
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 partonlevel 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.
