1049. Energy correlators for gluon splitting to heavy quarks

João Martins da Silva (LIP - Lisboa / ULisboa - IST)

Jets

Oral

Energy correlators inside of high energy jets provide a powerful tool to image the intrinsic and emergent angular scales of QCD. They have the potential to provide unprecedented insight on the interplay between vacuum scales inside of a jet and its medium modification. Energy correlators of jets containing a gluon splitting to heavy quarks can provide unique experimental access to two- and...

1047. A generalized picture of colour decoherence in dense QCD media

Xoán Mayo López (Universidade de Santiago de Compostela - IGFAE)

Jets

Oral

One of the most striking modifications induced by the QGP on a QCD parton shower is the breaking of angular-ordering. This was established in a series of pioneering papers almost 15 years ago by studying the radiation pattern off a QCD antenna in the presence of a medium [1,2]. These effects were captured by a single critical angle solely depending on the medium properties. Constraining the...

1113. sPHENIX measurements of high-pT neutral mesons and isolated photons in p+p collisions

Jets

Oral

The sPHENIX experiment is a next-generation collider detector at RHIC designed for rare jet and heavy flavor probes of the Quark-Gluon Plasma. The experiment includes a large-acceptance, granular electromagnetic calorimeter (EMCal) and very high-rate data acquisition plus trigger system. In RHIC
Run-24, sPHENIX sampled 107/pb of p+p collision data at 200 GeV using an efficient high-pT photon...

1027. Heavy-flavor and exotic hadron production in jets at LHCb

Ezra Lesser (CERN)

10/04/2025, 10:00

Jets

Oral

Jets offer a unique laboratory for studying the production of heavy-flavor hadrons and quarkonia, including exotic hadron candidates.
With a full range of precision vertexing, tracking, and particle ID capabilities covering forward rapidity, the LHCb experiment is especially well suited to measurements of heavy-flavor and exotic hadron production. This talk will present recent LHCb studies...

981. The first measurement of energy-energy correlator of jets in PbPb collisions at CMS

Jussi Viinikainen (Vanderbilt University (US))

10/04/2025, 10:20

Jets

Oral

Energy-energy correlators can isolate physics of different angular scales, which has attracted a lot of interest recently to study it in heavy ion environments. Any modification from proton-proton reference can reveal hints about the inner workings of the quark-gluon plasma. In this presentation, we will present the first measurement of the energy-energy correlator of jets in heavy ion...
