Abstract
A full, nonperturbative renormalization group analysis of interacting\nelectrons in a graphite layer is performed, in order to investigate the\ndeviations from Fermi liquid theory that have been observed in the experimental\nmeasures of a linear quasiparticle decay rate in graphite. The electrons are\ncoupled through Coulomb interactions, which remain unscreened due to the\nsemimetallic character of the layer. We show that the model flows towards the\nnoninteracting fixed-point for the whole range of couplings, with logarithmic\ncorrections which signal the marginal character of the interaction separating\nFermi liquid and non-Fermi liquid regimes.\n
