8. Resummation of Sudakov Shoulder Logarithms in Heavy Jet Mass

Mr Xiaoyuan Zhang (Harvard University)

29/03/2023, 16:00

Sudakov shoulder arises from incomplete cancellations between virtual corrections and real emissions in the perturbation theory of some event shape observables, like thrust, heavy jet mass and C parameter. We present the next-to-next-to-leading logarithmic (NNLL) resummation of Sudakov shoulders in the heavy jet mass. The appearance of spurious Sudakov Landau poles is ameliorated by resumming...

38. Resummation for photon isolation

Thomas Becher

29/03/2023, 16:30

To separate the energetic photons produced in hard scattering processes from those from other sources, measurements impose isolation requirements which restrict the hadronic radiation inside a cone around the photon. In our talk we explain that for small cone radius R, photon isolation effects can be captured by a fragmentation function describing the decay of a parton into a photon...

27. Nucleon Energy-Energy Correlator in Lepton-Ion Collisions

Mr Haotian Cao (Beijing Normal University)

29/03/2023, 17:00

In this talk, I will introduce the concept of the nucleon energy energy correlator (neec). I will argue how this quantity can be measured in the dis process and present the NLL results.
