We investigate the Charge-Charge Correlation (QQC) in electron-positron annihilation as a probe of charge dynamics in Quantum Chromodynamics. [...]

Physics case for low-$\sqrt{s}$ QCD studies at FCC-ee / Verbytskyi, Andrii (Garching, Max Planck Inst.) ; d'Enterria, David (CERN) ; Monni, Pier Francesco (CERN) ; Skands, Peter (Monash U.)
Measurements of hadronic final states in $e^{+}e^{-}$ collisions at centre-of-mass (CM) energies below the Z peak can notably extend the FCC-ee physics reach in terms of precision quantum chromodynamics (QCD) studies. [...]

Planar Six-Point Feynman Integrals for Four-Dimensional Gauge Theories / Abreu, Samuel (CERN ; U. Edinburgh, Higgs Ctr. Theor. Phys.) ; Monni, Pier Francesco (CERN) ; Page, Ben (Gent U.) ; Usovitsch, Johann (CERN ; Humboldt U., Berlin (main))
We compute all planar two-loop six-point Feynman integrals entering scattering observables in massless gauge theories such as QCD. A central result of this paper is the formulation of the differential-equations method under the algebraic constraints stemming from four-dimensional kinematics, which in this case leaves only 8 independent scales. [...]

The two-loop fully differential soft function for $Q\overline{Q }V$ 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. The calculation is performed by reducing the relevant Feynman integrals into a canonical basis of master integrals by means of integration-by-parts identities. [...]

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. This entails the development of an algorithm for nesting triple-collinear splitting functions. [...]

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. [...]

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. London) ; Helliwell, Jack (Oxford U., Theor. Phys.) ; Karlberg, Alexander (CERN) ; Monni, Pier Francesco (CERN) ; Salam, Gavin P. (Oxford U., Theor. Phys. ; U. 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. The key to this advance lies in the identification of the relation between critical NNLL analytic resummation ingredients and their parton-shower counterparts. [...]

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.
