    • Dynamical Grooming meets LHC data 

      Caucal, Paul; Soto-Ontoso, Alba; Takacs, Adam (Journal article; Peer reviewed, 2021)
      In this work, we analyse the all-orders resummation structure of the momentum sharing fraction, zg, opening angle, θg, and relative transverse momentum, kt,g, of the splitting tagged by the Dynamical Grooming procedure in ...

    • Dynamical grooming of QCD jets 

      Mehtar-Tani, Yacine; Soto-Ontoso, Alba; Tywoniuk, Konrad (Journal article; Peer reviewed, 2020-02-06)
      We propose a new class of infrared-collinear and Sudakov safe observables with an associated jet grooming technique that removes dynamically soft and large angle branches. It is based on identifying the hardest branch in ...

    • Dynamically groomed jet radius in heavy-ion collisions 

      Caucal, Paul; Soto-Ontoso, Alba; Takacs, Adam (Journal article; Peer reviewed, 2022)
      We explore the ability of a recently proposed jet substructure technique, dynamical grooming, to pin down the properties of the quark-gluon plasma formed in ultrarelativistic heavy-ion collisions. In particular, we compute, ...

    • Medium-induced radiative kernel with the Improved Opacity Expansion 

      Barata, João; Mehtar-Tani, Yacine; Soto-Ontoso, Alba; Tywoniuk, Konrad (Journal article; Peer reviewed, 2021)
      We calculate the fully differential medium-induced radiative spectrum at next-to-leading order (NLO) accuracy within the Improved Opacity Expansion (IOE) framework. This scheme allows us to gain analytical control of the ...

    • Revisiting transverse momentum broadening in dense QCD media 

      Barata, João; Mehtar-Tani, Yacine; Soto-Ontoso, Alba; Tywoniuk, Konrad (Journal article; Peer reviewed, 2021)
      We reconsider the problem of transverse momentum broadening of a highly energetic parton suffering multiple scatterings in dense colored media, such as the thermal quark-gluon plasma or large nuclei. In the framework of ...

    • Tagging boosted hadronic objects with dynamical grooming 

      Mehtar-Tani, Yacine; Tywoniuk, Konrad; Soto-Ontoso, Alba (Journal article; Peer reviewed, 2020)
      We evaluate the phenomenological applicability of the dynamical grooming technique, introduced by Y. Mehtar-Tani, A. Soto-Ontoso, and K. Tywoniuk [Phys. Rev. D 101, 034004 (2020)], to boosted W and top tagging at LHC ...
