106. Energy Correlators, Heavy Flavor, and Precision QCD

Evan Craft (Yale University)

7/31/23, 3:20 PM

Jet substructure has been successful in broadening our understanding of fundamental physics and QCD. In this talk, I will introduce a variety of new energy correlator based observables, specifically the two and three point heavy energy correlators, which measure correlations of energy flow at collider experiments on heavy quarks. These observables provide new insights into jet substructure,...

125. Measurements of energy correlators in jets and alphas extraction at CMS

Chenfeng Lu

7/31/23, 3:40 PM

The energy correlators inside jets are measured for the first time at the CMS experiment. AlphaS is determined from the ratio of 3-point and 2-point correlators.

96. Imaging Intrinsic and Emergent Scales of the QGP with Energy Correlators

Ian Moult

7/31/23, 4:00 PM

We will describe an approach to resolving the scales of the QGP using the recently introduced energy correlator observables, showing how these observables enable one to cleanly extract the dynamics of the plasma as a function of scale. We consider the case of both massless and heavy quark jets, and highlight how heavy quark energy correlators provide a particularly sensitive probe of the QGP...

97. Jet observables in anisotropic QCD matter

Joao Barata (BNL)

7/31/23, 4:20 PM

In recent years, we have seen a rapid development in the description of jets evolving in the presence of structured QCD matter, as the one produced in heavy ions collisions. So far, such theoretical progress has been discussed only at the level of quantities which can not be directly measured. In this talk, I will present the first steps towards understanding the impact of the medium's...

80. Imaging Cold Nuclear Matter with Energy Correlators at the future EIC

Kyle Devereaux (Lawrence Berkeley National Laboratory)

7/31/23, 4:40 PM

The future Electron-Ion Collider (EIC) will provide the first electron-nucleus collisions for a variety of nuclei species with high luminosity, wide kinematic coverage, and excellent detector resolution, providing new insights into cold nuclear matter effects and transport phenomena. As jets are an accurate proxy of the struck quark that traverses the nucleus, the signature of the nuclear...

100. Hadro-production of massive b-jets and associated dead-cone effects at the LHC

Oleh Fedkevych

7/31/23, 5:00 PM

Jet sub-structure observables are known to be sensitive to the effects
due to mass of partons produced via hard scattering QCD interactions.
For example, QCD predicts the suppression of collinear emission around a
massive quark called dead-cone effect and it was recently observed by
the ALICE collaboration at the LHC.

In this talk, we discuss how the quark mass affect the...
