Universality and Evolution of TMDs
S. Mert Aybat, Ted C. Rogers
In this talk, we summarize how QCD evolution can be exploited to improve the treatment of transverse momentum dependent (TMD) parton distribution and fragmentation functions. The m…
The QCD Evolution of the Sivers Function
S. Mert Aybat, John C. Collins, Jian-Wei Qiu +1
We extend the Collins-Soper-Sterman (CSS) formalism to apply it to the spin-dependence governed by the Sivers function. We use it to give a correct numerical QCD evolution of exist…
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…
TMD Parton Distribution and Fragmentation Functions with QCD Evolution
S. Mert Aybat, Ted C. Rogers
We assess the current phenomenological status of transverse momentum dependent (TMD) parton distribution functions (PDFs) and fragmentation functions (FFs) and study the effect of…
Bulk Fermions in Soft Wall Models
S. Mert Aybat, Jose Santiago
We discuss the implementation of bulk fermions in soft wall models. The introduction of a position dependent bulk mass allows for a well defined Kaluza-Klein expansion for bulk fer…
Bulk Fermions in Warped Models with a Soft Wall
S. Mert Aybat, Jose Santiago
We study bulk fermions in models with warped extra dimensions in the presence of a soft wall. Fermions can acquire a position dependent bulk Dirac mass that shields them from the d…
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…
