77. Understanding Jet Charge

Andrew Larkoski

8/3/23, 1:20 PM

The jet charge is an old observable that has proven uniquely useful for discrimination of jets initiated by different flavors of light quarks, for example. In this Letter, we propose an approach to understanding the jet charge by establishing simple, robust assumptions that hold to good approximation non-perturbatively, such as isospin conservation and large particle multiplicity in the jets,...

102. Energy Correlators taking Charge

Kyle Lee (MIT)

8/3/23, 1:40 PM

Recently, spurred by significant theoretical advances, an exciting program has been launched to reframe jet substructure in terms of multipoint correlation functions of energy flow operators. These energy correlators successfully image the intrinsic and emergent scales of QCD as a function of scale with many interesting phenomenological applications.

In this talk, we present an exciting...

122. Beyond the Narrow-Width Limit for Off-shell and Boosted Top Quark Decays

Christoph Regner (University of Vienna)

8/3/23, 2:00 PM

Due to its large mass the top quark plays an important role in consistency checks of the Standard Model and new-physics searches. Studies concerning precise theoretical predictions of the top production and its decay are commonly based on the narrow-width (NW) limit of the top quark propagator or on full off-shell computations. The NW limit, where the top quark is treated as an on-shell...

111. Interpretation of the top quark mass parameter in Monte Carlo samples at NNLL precision

Naseem Bouchhar (IFIC - Univ. of Valencia and CSIC (ES))

8/3/23, 2:20 PM

We provide a quantitative interpretation for direct top quark mass measurements in terms of a field-theoretic mass scheme. A relation between the top quark mass parameter in Monte Carlo generators and the MSR mass at a scale of R = 3 GeV is derived. This is achieved by fitting Monte Carlo templates for the simulated jet mass distribution of large-radius jets containing a hadronically-decaying...

75. CaloClouds: Fast Geometry-Independent Highly-Granular Calorimeter Simulation

Sascha Diefenbacher (Lawrence Berkeley National Laboratory)

Accurate and precise calorimeter modeling presents one of the most significant computational bottlenecks in modern high-energy physics simulation chains. For this reason, extensive work has been done to speed up calorimeter simulation and make it more computationally efficient. A highly promising method for achieving this speed-up is generative machine learning (ML) models. However, most...
