25. Inclusive Dijet and Heavy Flavour Jet Production at ATLAS

Talk

We present new jet production results from ATLAS. Measurements of multi-differential dijet production using the full Run 2 data set are compared to state-of-the-art predictions. In addition a new measurement of W production in association with b-jets provides an important test of perturbative quantum chromodynamics (pQCD) in the presence of heavy quarks.

2. Phenomenology of heavy flavour jet angularities at hadron colliders

Talk

We compute resummed and matched predictions for jet angularities in hadronic $Z+$jet events, where the jet is initiated by a $b$-quark. The analysis is performed both with and without grooming the candidate jets using the SoftDrop algorithm. Mass effects are consistently included at both fixed-order and resummed levels.
Our theoretical predictions also incorporate non-perturbative...

58. Lund jet planes of hidden and double-open heavy-flavor jets

Talk

Measurements of quarkonium-in-jet fragmentation have established that hidden heavy-flavor hadrons, such as $J/\psi$ ($c\bar c$) and $\Upsilon$ ($b\bar b$) states, are produced copiously within active jet showers. This has motivated new developments in parton shower algorithms, opening a broader avenue for heavy-flavor jet substructure studies. We present a comparative phenomenological study of...

55. Jet Substructure Observables as Probes of Heavy Neutrino Polarization in Boosted W′ Decays at the HL-LHC

Songshaptak De (Jožef Stefan Institute)

7/14/26, 5:30 PM

Talk

We present a jet substructure-based polarimetry framework for boosted heavy neutrino fat jets at the HL-LHC, with the goal of probing the chiral structure of heavy $W'$ interactions. In the boosted regime, a heavy neutrino $N$ produced via $pp \to W' \to \ell N$ and decaying as $N \to \ell jj$ gives rise to a collimated final state. This final state can be reconstructed as a large-radius...
