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…
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…
Anomalous dimensions and critical exponents for the Gross-Neveu-Yukawa model at five loops
J. A. Gracey, A. Maier, P. Marquard +1
We renormalize the Gross-Neveu-Yukawa model with an symmetry to in dimensions and determine the anomalous dimensions of the fermion and scalar f…
