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. Bottom-quark effects in Higgs production at intermediate transverse momentum / Caola, Fabrizio ; Lindert, Jonas ; Melnikov, Kirill ; Monni, Pier ; et al
We provide a precise description of the Higgs boson transverse momentum distribution including top and bottom quark contributions, that is valid for transverse momenta in the range m b  ≲  p ⊥  ≲  m t , where m b and m t are the bottom and top quark masses. [...]
