Collider observables can broadly be grouped into two classes: global observables, like e.g. many event shapes, and non-global observables, whose defining property is that they are sensitive to radiation only in part of the phase space. Non-globality gives rise to a special type of large logarithm, whose resummation is more involved than resummation in the global case. A framework to resum...
In this talk, I present a state-of-the-art analysis of the 1-jettiness event shape using Soft-Collinear Effective Theory (SCET). This work achieves N$^3$LL + $\mathcal{O}(\alpha_s)$ acccuracy with full fixed-order matching and inclusion of nonperturbative corrections. It stands among the most precise event-shape predictions in DIS to date and enables competitive extractions of both the strong...
In this talk we will discuss the first hadron-level predictions at MEPS@NLO precision for both neutral and charged current DIS at the EIC and the first application of the MEPS@NLO technique to charged current DIS in general. In recent years, lepton-hadron scattering has garnered more attention again due to the upcoming
planned for the Electron-Ion Collider (EIC) at Brookhaven National...
Production of multiple jets or vector bosons plus jets at the LHC offers the main, and unprecedented opportunity to study QCD at the high-energy regime. As precision advances, attention has been brought up to study further topics sensitive to understanding of QCD: different topological configurations between vector bosons and jets, the jet substructure information, and the heavy-flavor...
The spin-1 nature of gluon caused correlations in subsequent parton radiations insdie jets. Such effects were fully incorporated in limited parton shower models. The correlation is measured for the first time in experiments, and compared to MC models.
Spin correlations between QCD emissions have so far been neglected in most of the parton shower algorithms commonly used for LHC predictions. However, their inclusion is crucial to achieve NLL accuracy or to include NLO contributions in these algorithms.
In this talk, we present a new algorithm for incorporating spin correlations into parton shower algorithms. Instead of using spin density...
Lepton-proton Deep Inelastic Scattering (DIS) is a fundamental process for both the strong and weak sectors of the Standard Model, playing a crucial role in the measurement of the parton distribution functions of the proton, one of the main goals of the EIC program.
On the theory side, however, since the starting of the LHC operations, the community has been focused on QCD corrections to...
