Popis: Abstract We compute the three-loop master integrals required for the calculation of the triple-real contribution to the N3LO quark beam function due to the splitting of a quark into a virtual quark and three collinear gluons, q → q * + ggg. This provides an important ingredient for the calculation of the leading-color contribution to the quark beam function at N3LO.
