Heavy Quark Production in Soft Collinear Effective Theory

If you have a question about this talk, please contact Damien George .

Heavy quarks play an important role in collider experiments. Many theoretical tools are currently available, which allow to obtain a successful description of heavy flavor production in fully inclusive observables, or at moderate energies, close the scale of the quark mass. However, as the production energy increases, large logarithms appear, threatening the convergence of the perturbative series, and introducing large theoretical uncertainties. The hierarchy between the scales of the hard scattering and of the quark mass can be exploited to establish an effective field theory treatment of heavy quark production. Using Soft Collinear Effective Theory (SCET), I will show how the dynamics at the different scales that enter heavy flavor production processes can be factorized, and large logarithms can be resummed through renormalization group equations.

This talk is part of the HEP phenomenology joint Cavendish-DAMTP seminar series.
