Discussion Overview
The discussion centers around the concept of exclusive measurements in the context of higher order QCD calculations relevant for experiments at the LHC. Participants explore the definitions, implications, and methodologies associated with exclusive measurements, including whether these calculations are performed using lattice methods or perturbative analysis.
Discussion Character
- Exploratory
- Technical explanation
- Conceptual clarification
Main Points Raised
- One participant seeks clarification on what constitutes an exclusive measurement and its significance in QCD calculations.
- Another participant defines exclusive measurements as processes where only specific outcomes are considered, providing examples such as detecting only J/Psi or exactly three jets.
- It is noted that calculations for hard processes are typically done using perturbative methods, while hadron properties may differ.
- A follow-up question suggests that exclusive measurements may also involve looking for the production of a species through particular decay channels.
- Further clarification indicates that exclusive measurements can relate to specific production processes, contrasting them with inclusive measurements that consider all possible processes.
Areas of Agreement / Disagreement
Participants generally agree on the definition of exclusive measurements, but there are nuances in understanding the context and implications of these measurements, indicating that the discussion remains exploratory and unresolved in some aspects.
Contextual Notes
Some assumptions about the context of exclusive measurements and their applications in QCD calculations are not fully articulated, and the discussion does not resolve whether lattice methods or perturbative analysis is preferred for these calculations.
