71. Collinear contributions to QCD resummations

Dr Prasanna K. Dhani (IFIC, University of Valencia - CSIC)

4/16/24, 4:30 PM

Talk

Infrared singular factors originating from the QCD factorisation of scattering amplitudes in soft and collinear limits play an important role both in the organisation and in the calculation of the higher-order contributions to hard scattering cross sections. In this talk I will report on recent work for the evaluation of collinear contributions to QCD resummations of hard scattering...

72. Towards NLL resummation of angularities with recoil

Ankita Budhraja (Nikhef)

Talk

Jet angularities are a class of substructure observables whose sensitivity to angular distribution of radiation in a jet is controlled by a continuous parameter ‘$b$’ (with, $b > −1$ for IR safety). For $b$ close to $0$, the effect of recoil of collinear emissions due to soft radiations in the jet is a leading power effect while it gets power suppressed as $b$ approaches $1$. In a previous...

53. Diffractive factorization using effective field theory

Kyle Lee (MIT)

4/16/24, 5:30 PM

Talk

Diffractive processes are events with large rapidity gaps, which typically comprise a double-digit percent of events at colliders. Last year I discussed coherent diffraction with an intact scattered proton, whereas in this talk I focus on incoherent diffraction, where the proton is scattered into a jet. We derive the factorization of this process using Glauber SCET, showing that it splits...
