We present a generalization of the dipole subtraction scheme for computing jet cross sections in electron-positron annihilation at next-to-next-to-leading order accuracy in perturbative QCD. In this first part we deal with the regularization of the doubly-real contribution to the NNLO correction. 
A New subtraction scheme for computing QCD jet cross sections at next-to-leading order accuracy
We present a new subtraction scheme for computing jet cross sections in electron-positron annihilation at next-to-leading order accuracy in perturbative QCD. The new scheme is motivated by problems
IR subtraction schemes: integrating the counterterms at NNLO in QCD
We briefly review a subtraction scheme for computing radiative corrections to QCD jet cross sections that can be defined at any order in perturbation theory. Hereafter we discuss the computational
Perturbation theory of computing QCD jet cross sections beyond NLO accuracy
We discuss the problems that arise when one wishes to extend the existing general methods of computing radiative corrections to QCD jet cross sections to beyond next-to-leading order. Then we present
Double real radiation corrections to tt̄ production at the LHC: the all-fermion processes
We present the double real radiation corrections to the hadronic tt̄ production stemming from partonic processes with fermions only. For this purpose, we extend the NNLO antenna subtraction formalism
Analytic integration of soft and collinear radiation in factorised QCD cross sections at NNLO
Abstract Within the framework of local analytic sector subtraction, we present the full analytic integration of double-real and real-virtual local infrared counterterms that enter NNLO QCD
The fully differential hadronic production of a Higgs boson through bottom-quark fusion at NNLO
A bstractThe fully differential computation of the hadronic production cross section of a Higgs boson via bottom quarks is presented at NNLO in QCD. Several differential distributions with their
Jet production in the CoLoRFulNNLO method: event shapes in electron-positron collisions
We present the CoLoRFulNNLO method to compute higher order radiative corrections to jet cross sections in perturbative QCD. We apply our method to the computation of event shape observables in
The fully differential decay rate of a Higgs boson to bottom-quarks at NNLO in QCD
A bstractThe decay of a light Higgs boson to bottom quarks is dominant and can be exploited for the discovery of the Higgs particle and the measurement of its properties at the LHC and future
Higgs-differential cross section at NNLO in dimensional regularisation
A bstractWe present an analytic computation of the Higgs production cross section in the gluon fusion channel, which is differential in the components of the Higgs momentum and inclusive in the

Subtraction at NNLO
We propose a framework for the implementation of a subtraction formalism at NNLO in QCD, based on an observable- and process-independent cancellation of infrared singularities. As a first simple
Matching of singly- and doubly-unresolved limits of tree-level QCD squared matrix elements
We describe how to disentangle the singly- and doubly-unresolved (soft and/or collinear) limits of tree-level QCD squared matrix elements. Using the factorization formulae presented in this paper, we
