The two-loop fully differential soft function for $Q\bar{Q}V$ production at lepton colliders / Liu, Ze Long (Beijing, Inst. High Energy Phys.) ; Monni, Pier Francesco (CERN)
We consider the production of a pair of heavy quarks $Q\bar{Q}$ in association with a generic colour singlet system $V$ at lepton colliders, and present the first analytic calculation of the two-loop soft function differential in the total momentum of the real radiation. [...]

A collinear shower algorithm for NSL non-singlet fragmentation / van Beekveld, Melissa (NIKHEF, Amsterdam) ; Dasgupta, Mrinal (Manchester U.) ; El-Menoufi, Basem Kamal (Monash U.) ; Helliwell, Jack (Oxford U., Theor. Phys.) ; Monni, Pier Francesco (CERN) ; Salam, Gavin P. (Oxford U., Theor. Phys. ; U. Oxford (main))
We formulate a collinear partonic shower algorithm that achieves next-to-single-logarithmic (NSL, $\alpha_s^n L^{n-1}$) accuracy for collinear-sensitive non-singlet fragmentation observables. [...]

Scaling Violation in Power Corrections to Energy Correlators from the Light-Ray Operator Product Expansion / Chen, Hao (Zhejiang U., Inst. Mod. Phys.) ; Monni, Pier Francesco (CERN) ; Xu, Zhen (Zhejiang U., Inst. Mod. Phys.) ; Zhu, Hua Xing (Peking U. ; Peking U., CHEP)
In recent years, energy correlators have emerged as a powerful tool to explore the field theoretic structure of strong interactions at particle colliders. In this Letter we initiate a novel study of the non-perturbative power corrections to the projected $N$-point energy correlators in the limit where the angle between the detectors is small. [...]

A new standard for the logarithmic accuracy of parton showers / van Beekveld, Melissa (Nikhef, Amsterdam) ; Dasgupta, Mrinal (Manchester U.) ; El-Menoufi, Basem Kamal (Monash U.) ; Ferrario Ravasio, Silvia (CERN) ; Hamilton, Keith (University Coll.

Oxford (main)) ; Scyboz, Ludovic (Monash U.) et al.
We report on a major milestone in the construction of logarithmically accurate final-state parton showers, achieving next-to-next-to-leading-logarithmic (NNLL) accuracy for the wide class of observables known as event shapes. [...]

Two-loop anomalous dimensions for small-$R$ jet versus hadronic fragmentation functions / van Beekveld, Melissa (Nikhef, Amsterdam) ; Dasgupta, Mrinal (Manchester U.) ; El-Menoufi, Basem Kamal (Manchester U. ; Monash U.) ; Helliwell, Jack (Oxford U., Theor. Phys.) ; Karlberg, Alexander (CERN) ; Monni, Pier Francesco (CERN)
We study the collinear fragmentation of highly energetic jets defined with a small jet radius. In particular, we investigate how the corresponding fragmentation functions differ from their hadronic counterpart defined in the common $\overline{\rm MS}$ scheme. [...]

Introduction to the PanScales framework, version 0.1 / van Beekveld, Melissa (Nikhef, Amsterdam) ; Dasgupta, Mrinal (Manchester U.) ; El-Menoufi, Basem Kamal (Manchester U. ; Monash U.) ; Ravasio, Silvia Ferrario (CERN) ; Hamilton, Keith (U. Coll. London) ; Helliwell, Jack (Oxford U.) ; Karlberg, Alexander (CERN) ; Medves, Rok (Oxford U.) ; Monni, Pier Francesco (CERN) ; Salam, Gavin P. (Oxford U.) et al.
In this article, we document version 0.1 of the PanScales code for parton shower simulations. With the help of a few examples, we discuss basic usage of the code, including tests of logarithmic accuracy of parton showers. [...]

Collinear fragmentation at NNLL: generating functionals, groomed correlators and angularities / van Beekveld, Melissa (Oxford U., Theor. Phys.) ; Dasgupta, Mrinal (Manchester U. ; CERN) ; El-Menoufi, Basem Kamal (Manchester U.) ; Helliwell, Jack (Oxford U., Theor. Phys.) ; Monni, Pier Francesco (CERN)
Jet calculus offers a unique mathematical technique to bridge the area of QCD resummation with Monte Carlo parton showers. With the ultimate goal of constructing next-to-next-to-leading logarithmic (NNLL) parton showers we study, using the language of generating functionals, the collinear fragmentation of final-state partons.

Exploring High-Purity Multiparton Scattering at Hadron Colliders / Andersen, Jeppe R. (Durham U.) ; Monni, Pier Francesco (CERN) ; Rottoli, Luca (Zurich U.) ; Salam, Gavin P. (Oxford U., Theor. Phys. ; Oxford U.) ; Soto-Ontoso, Alba (CERN)
Multi-parton interactions are a fascinating phenomenon that occur in almost every high-energy hadron--hadron collision, yet are remarkably difficult to study quantitatively. In this letter we present a strategy to optimally disentangle multi-parton interactions from the primary scattering in a collision. [...]

Quark and gluon two-loop beam functions for leading-jet $p_T$ and slicing at NNLO / Abreu, Samuel (CERN ; U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Gaunt, Jonathan R. (Manchester U.) ; Monni, Pier Francesco (CERN) ; Rottoli, Luca (Zurich U.) ; Szafron, Robert (Brookhaven)
We compute the complete set of two-loop beam functions for the transverse momentum distribution of the leading jet produced in association with an arbitrary colour-singlet system. Our results constitute the last missing ingredient for the calculation of the jet-vetoed cross section at small veto scales at the next-to-next-to-leading order, as well as an important ingredient for its resummation to next-to-next-to-next-to-leading logarithmic order.

Theory uncertainties in the fiducial Drell-Yan cross section and distributions / Chen, Xuan (KIT, Karlsruhe, TP ; KIT, Karlsruhe, IAP) ; Gehrmann, Thomas (Zurich U.) ; Glover, Nigel (Durham U., IPPP) ; Huss, Alexander (CERN) ; Monni, Pier Francesco (CERN) ; Re, Emanuele (Milan Bicocca U. ; INFN, Milan Bicocca ; Annecy, LAPTH) ; Rottoli, Luca (Zurich U.) ; Torrielli, Paolo (INFN, Turin ; Turin U.)
In these proceedings we study various sources of theoretical uncertainty in the Drell-Yan $p_T^{{\ell\ell}}$ spectrum focussing on the $p_T^{{\ell\ell}} \lesssim 100\, {\rm GeV}$ region. [...]
