Abstract

I present a method for calculating heavy quark production which extrapolates smoothly from the well understood limits of the fixed-flavour number scheme for Q² approx m_H² to the zero-mass scheme at Q²/m_H² -> infinity. For all Q² > m_H² the evolution of the heavy quark distribution is precisely as in the massless MSbar scheme. The method is simple to implement and compares well with data.
