TMD-factorization, Factorization Breaking and Evolution
S. M. Aybat, T. C. Rogers
We give an overview of the current status of perturbative QCD factorization theorems in processes that involve transverse momentum dependent (TMD) parton distribution functions (PD…
Soft-Gluon Cancellation, Phases and Factorization with Initial-State Partons
S. Mert Aybat, George Sterman
We outline arguments for the cancellation of soft singularities in transition probabilities and parton distributions with incoming partons and Wilson lines, and with observed jets…
The one-loop gluon amplitude for heavy-quark production at NNLO
Charalampos Anastasiou, S. Mert Aybat
We compute the one-loop QCD amplitude for the process gg-->Q\bar{Q} in dimensional regularization through order ε^2 in the dimensional regulator and for arbitrary quark mass values…
The Two-loop Soft Anomalous Dimension Matrix and Resummation at Next-to-next-to Leading Pole
S. Mert Aybat, Lance J. Dixon, George Sterman
We extend the resummation of dimensionally-regulated amplitudes to next-to-next-to-leading poles. This requires the calculation of two-loop anomalous dimension matrices for color m…
The Two-loop Anomalous Dimension Matrix for Soft Gluon Exchange
S. Mert Aybat, Lance J. Dixon, George Sterman
The resummation of soft gluon exchange for QCD hard scattering requires a matrix of anomalous dimensions. We compute this matrix directly for arbitrary 2 to n massless processes fo…
