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. [...]

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. 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.

QCD resummation for groomed jet observables at NNLL+NLO / Dasgupta, Mrinal (Manchester U. ; CERN) ; El-Menoufi, Basem Kamal (Manchester U.) ; Helliwell, Jack (Oxford U., Theor. Phys.)
We use a direct QCD approach to carry out the next-to-next-to-leading logarithmic (NNLL) resummation for observables groomed with the modified mass-drop tagger (Soft Drop $\beta=0$). We focus on observables which are additive given an arbitrary number of soft-collinear emissions. [...]

Parton Showers beyond Leading Logarithmic Accuracy / Dasgupta, Mrinal (U. Manchester (main)) ; Dreyer, Frédéric A. (Oxford U., Theor. Phys.) ; Hamilton, Keith (U. Coll. London) ; Monni, Pier Francesco (CERN) ; Salam, Gavin P. (Oxford U., Theor. Phys.) ; Soyez, Gregory (IPhT, Saclay)
Parton showers are among the most widely used tools in collider physics. Despite their key importance, none so far has been able to demonstrate accuracy beyond a basic level known as leading logarithmic (LL) order, with ensuing limitations across a broad spectrum of physics applications. [...]

Monte Carlo event generators (MCEGs) are the indispensable workhorses of particle physics, bridging the gap between theoretical ideas and first-principles calculations on the one hand, and the complex detector signatures and data of the experimental community on the other hand. [...]

Logarithmic accuracy of parton showers: a fixed-order study / Dasgupta, Mrinal (Manchester U.) ; Dreyer, Frédéric A. (MIT, Cambridge, CTP) ; Hamilton, Keith (University Coll. London ; CERN) ; Monni, Pier Francesco (CERN) ; Salam, Gavin P. (CERN ; MIT)
We formulate some first fundamental elements of an approach for assessing the logarithmic accuracy of parton-shower algorithms based on two broad criteria: their ability to reproduce the singularity structure of multi-parton matrix elements, and their ability to reproduce logarithmic resummation results. We illustrate our approach by considering properties of two transverse momentum ordered final-state showers, examining features up to second order in the strong coupling. [...]
