29. The $q_T$ spectrum for Higgs production via quark annihilation at N${}^3$LL'+ aN${}^3$LO

Ms Rebecca von Kuk (DESY)

Due to the limited detector resolution and the challenges involving the tagging of individual quark flavors, it is difficult to measure the Yukawa coupling of bottom, charm and strange quarks from the final state.
A precise prediction of the $q_T$ spectrum for Higgs production via quark annihilation allows to access the Yukawa coupling for bottom and lighter quarks from the initial state as...

30. Azimuthal decorrelation and the Winner-Takes-All axis

Rudi Rahn (University of Manchester)

The azimuthal decorrelation between a vector boson and a jet is an essential hard probe in high energy proton-proton and heavy-ion collisions. It suffers from large logarithms in the back-to-back limit, which can be resummed using SCET. In this talk I will demonstrate that by adopting the Winner-Takes-All recombination scheme the observable's theoretical treatment simplifies tremendously,...

31. One-jettiness resummation for color singlet plus jet production at hadron colliders

Simone Alioli (UNIMIB & INFN)

We present results for the resummation of one-jettiness (Tau1) for the production of a color singlet system associated with a hard jet at hadron colliders, up to NNLL' accuracy. As a case study we focus on Z+1jet production at the LHC. We study different definitions of Tau1, depending on the frame in which one-jettiness is defined, assessing the size of the higher-order logarithmic corrections...
