1. Triple-real contribution to the quark beam function in QCD at next-to-next-to-next-to-leading order / Melnikov, K. ; Rietkerk, R. ; Tancredi, L. ; Wever, C.
We compute the three-loop master integrals required for the calculation of the triple-real contribution to the N 3 LO quark beam function due to the splitting of a quark into a virtual quark and three collinear gluons, q → q * + ggg . [...]

2. Double-real contribution to the quark beam function at N 3 LO QCD / Melnikov, K. ; Rietkerk, R. ; Tancredi, L. ; Wever, C.
We compute the master integrals required for the calculation of the double-real emission contributions to the matching coefficients of 0-jettiness beam functions at nextto-next-to-next-to-leading order in perturbative QCD. [...]

3. Unitarity methods for Mellin moments of Drell-Yan cross sections / Bonocore, Domenico ; Laenen, Eric ; Rietkerk, Robbert
We develop a method for computing Mellin moments of single inclusive cross sections such as Drell-Yan production directly from forward scattering diagrams, by invoking unitarity in the form of cutting equations. [...]
