Collinear fragmentation at NNLL: generating functionals, groomed correlators and angularities

Melissa van Beekveld, Mrinal Dasgupta, Basem Kamal El-Menoufi +2

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-le…

QCD resummation for groomed jet observables at NNLL+NLO

Mrinal Dasgupta, Basem Kamal El-Menoufi, Jack Helliwell

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 β=0). W…

Investigating top tagging with Ym​-Splitter and N-subjettiness

Mrinal Dasgupta, Jack Helliwell

We study top-tagging from an analytical QCD perspective focusing on the role of two key steps therein : a step to find three-pronged substructure and a step that places constraints…

Groomed jet mass as a direct probe of collinear parton dynamics

Daniele Anderle, Mrinal Dasgupta, Basem Kamal El-Menoufi +2

We study the link between parton dynamics in the collinear limit and the logarithmically enhanced terms of the groomed jet mass distribution, for jets groomed with the modified mas…
