A GPU compatible quasi-Monte Carlo integrator interfaced to pySecDec
S. Borowka, G. Heinrich, S. Jahn +3
The purely numerical evaluation of multi-loop integrals and amplitudes can be a viable alternative to analytic approaches, in particular in the presence of several mass scales, pro…
Standard Model Physics at the HL-LHC and HE-LHC
P. Azzi, S. Farry, P. Nason +223
The successful operation of the Large Hadron Collider (LHC) and the excellent performance of the ATLAS, CMS, LHCb and ALICE detectors in Run-1 and Run-2 with collisions at cen…
Multi-loop calculations: numerical methods and applications
S. Borowka, G. Heinrich, S. Jahn +3
We briefly review numerical methods for calculations beyond one loop and then describe new developments within the method of sector decomposition in more detail. We also discuss ap…
Expansion by regions with pySecDec
G. Heinrich, S. Jahn, S. P. Jones +6
We discuss the technique of expansion by regions from a geometric perspective, and its implementation within pySecDec, a toolbox for the evaluation of dimensionally regulated param…
pySecDec: a toolbox for the numerical evaluation of multi-scale integrals
S. Borowka, G. Heinrich, S. Jahn +4
We present pySecDec, a new version of the program SecDec, which performs the factorisation of dimensionally regulated poles in parametric integrals, and the subsequent numerical ev…
Numerical multi-loop calculations: tools and applications
S. Borowka, G. Heinrich, S. Jahn +4
We report on the development of tools to calculate loop integrals and amplitudes beyond one loop. In particular, we review new features of the program SecDec which can be used for…
NNLO predictions for Z-boson pair production at the LHC
G. Heinrich, S. Jahn, S. P. Jones +2
We present a calculation of the NNLO QCD corrections to Z-boson pair production at hadron colliders, based on the N-jettiness method for the real radiation parts. We discuss the si…
Numerical evaluation of two-loop integrals with pySecDec
S. Borowka, G. Heinrich, S. Jahn +3
We describe the program pySecDec, which factorises endpoint singularities from multi-dimensional parameter integrals and can serve to calculate integrals occurring in higher order…
Theory for the FCC-ee : Report on the 11th FCC-ee Workshop
A. Blondel, J. Gluza, S. Jadach +83
The Future Circular Collider (FCC) at CERN, a proposed 100-km circular facility with several colliders in succession, culminates with a 100 TeV proton-proton collider. It offers a…
