Parton distributions with threshold resummation / Bonvini, Marco ; Marzani, Simone ; Rojo, Juan ; Rottoli, Luca ; Ubiali, Maria ; Ball, Richard D ; Bertone, Valerio ; Carrazza, Stefano ; Hartland, Nathan P
We construct a set of parton distribution functions (PDFs) in which fixed-order NLO and NNLO calculations are supplemented with soft-gluon (threshold) resummation up to NLL and NNLL accuracy respectively, suitable for use in conjunction with any QCD calculation in which threshold resummation is included at the level of partonic cross sections. [...]

Bootstrapping correlation functions in N=4 SYM / Chicherin, Dmitry (Annecy, LAPTH) ; Doobary, Reza (Durham U., Dept. of Math.) ; Eden, Burkhard (Humboldt U., Berlin, Inst. Math. ; Humboldt U., Berlin) ; Heslop, Paul (Durham U., Dept. of Math.) ; Korchemsky, Gregory P (Saclay) ; Sokatchev, Emery (Annecy, LAPTH ; CERN ; Inst. U. de France)
We describe a new approach to computing the chiral part of correlation functions of stress-tensor supermultiplets in N=4 SYM that relies on symmetries, analytic properties and the structure of the OPE only. [...]
