Next-to-Next-to-Leading Order $N$-Jettiness Soft Function for One Massive Colored Particle Production at Hadron Colliders

Understand

The $N$-jettiness subtraction has proven to be an efficient method to perform differential QCD next-to-next-to-leading order (NNLO) calculations in the last few years.

• One important ingredient of this method is the NNLO soft function.
• We calculate this soft function for one massive colored particle production at hadron colliders.
• We select the color octet and color triplet cases to present the final results.
