Beam functions for $N$-jettiness at N$^3$LO in perturbative QCD
We present a calculation of all matching coefficients for N-jettiness beam functions at next-to-next-to-next-to-leading order (N$^{3}$LO) in perturbative quantum chromodynamics (QCD). Our computation is performed starting from the respective collinear splitting kernels, which we integrate using the...
