Résumé |
Perturbative calculations for processes involving heavy flavors
can be conducted using two approaches: the massive scheme and the massless
one. The former enables one to fully account for the heavy-quark
kinematics, while the latter allows one to resum potentially-large mass
logarithms. Furthermore, the two schemes can be combined to take advantage
of the virtues of each of them. Our starting point is to consider both
massive and massless calculations supplemented by soft-gluon resummation.
Establishing a smooth integration between resummed calculations in the
massive and massless schemes proves challenging, due to the
non-commutative nature of the soft and massless limits. In this
presentation, we derive an all-order expression that consistently resums
both mass and soft logarithms to next-to-leading logarithmic accuracy.
Finally, we will explore the applications of this formalism by studying
hadronic jets initiated by heavy flavors. |
