Precision Cell Resampling with a Relative and Resonant Aware Metric
Jeppe R. Andersen, Ella Cole, Andreas Maier
We present a metric on the space of scattering events based on relative transverse momenta and with explicit sensitivity to intermediate resonances. With this new metric, negative…
Heavy-Quark Condensate and Vacuum Energy Anomalous Dimension at Five Loops
Andreas Maier, Peter Marquard, York Schröder
We present the perturbative heavy-quark condensate at five-loop order in QCD. This constitutes the first calculation at this order accounting for non-vanishing quark masses. Our re…
The ultrafine splitting of heavy quarkonium with next-to-next-to-next-to-next-to-leading-order accuracy
Jose M. Escario, Andreas Maier, Clara Peset +1
We compute the hyperfine splitting of P-wave heavy quarkonium states with next-to-next-to-next-to-next-to-leading-order accuracy. The resummation of logarithms with next-to-next-to…
Towards QCD at Five Loops
Andreas Maier, Peter Marquard, York Schröder
We report on recent progress on five-loop calculations in perturbative QCD. We discuss the computation of the perturbative quark condensate, decoupling in QCD, and the precision de…
