## Abstract

Recently Russell et al. \[Phys. Rev. Lett. 120, 047401 (2018)\] have reported a clear signal of many-particle contributions to cyclotron resonance in high-mobility hBN-encapsulated graphene, observing significant variations of resonance energies as a function of the filling factor $\\nu$ for a series of interband channels. To elucidate their results, Coulombic contributions to the Landau-level spectra and cyclotron resonance in graphene are examined with a possible band gap taken into account and with emphasis on revealing electron-hole ($eh$) conjugation symmetry underlying such level and resonance spectra. Theory, based on the single-mode approximation, gives a practically good account of the experimental data; the data suggest a band gap of ~ 10 meV and show a profile that apparently reflects $eh$ conjugation symmetry.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
