47. NNLL resummations with ARES

Andrea Banfi (University of Sussex)

27/11/2019, 11:30

I present the ARES method for the resummation of final-state observables at NNLL accuracy. I discuss the main feature of the method, and the most important results obtained with it. I will then present its most recent developments.

46. Joint Higgs and jet transverse-momentum resummation in direct space

Paolo Torrielli (Istituto Nazionale di Fisica Nucleare)

27/11/2019, 12:00

I present recent developments in the direct-space resummation of transverse observables in colour-singlet production in the RadISH framework, with particular focus on the NNLL joint resummation for the transverse momentum of the Higgs boson and of the leading jet in gluon fusion at the LHC.

60. Soft gluon resummation in associated production of top-antitop pair and a H, Z or W boson

Leszek Motyka (Jagiellonian University)

Soft gluon resummation for associated t-tbar pair and a H, Z or W boson is performed up to the NNLL accuracy in QCD. The results are matched to the NLO QCD and calculations. The total hadroproduction cross sections at the LHC are obtained as well as selected kinematical distributions. It is shown that the resummation leads to higher theoretical precision. Results are compared to data from the LHC.
