TL;DR
This paper introduces the bermion approach, using negative flavor numbers and Bose statistics for fermions, to estimate dynamical fermion effects in lattice QCD.
Contribution
It proposes a novel method of extrapolating from negative to positive flavor numbers using bermions for lattice QCD simulations.

Bermion-based extrapolation provides insights into dynamical fermion effects.
The approach offers a new way to approximate fermion contributions in lattice QCD.
Results suggest potential for more efficient simulations of dynamical fermions.
Abstract
We estimate the effects of dynamical fermions by extrapolating to positive flavour numbers the results from negative values obtained by adding to the pure gauge sector a fermion action where the fields obey a Bose statistics: the bermions.
