Two-Loop Massive Quark Jet Functions in SCET

Understand

We calculate the $\mathcal O(\alpha_s^2)$ corrections to the primary massive quark jet functions in Soft-Collinear Effective Theory (SCET).

• They are an important ingredient in factorized predictions for inclusive jet mass cross sections initiated by massive quarks emerging from a hard interaction with smooth quark mass dependence.
• Due to the effects coming from the secondary production of massive quark-antiquark pairs there are two options to define the SCET jet function, which we call universal and mass mode jet functions.
• They are related to whether or not a soft mass mode (zero) bin subtraction is applied for the secondary massive quark contributions and differ in particular concerning the infrared behavior for vanishing quark mass.
