This is an exeercise about running a CMS Run2 new physics search analysis on CMS open data using ADL and CutLang.
ADL, or Analysis Description Language, is a domain-specific language for writing HEP analyses. CutLang is a runtime interpreter of ADL that can run ADL on events and perform other analysis tasks.
Information about ADL and CutLang can be found at: https://adl.web.cern.ch/
Prerequisites
- Basic knowledge on HEP analysis concepts.
- Very basic knowledge on ROOT
| Setup | Download files required for the lesson | |
| 00:00 | 1. Introduction |
What is ADL?
What is CutLang? Why would we use ADL/CutLang to write and perform analyses? |
| 00:15 | 2. Installing CutLang |
How do I access information about CutLang in general?
How do I install CutLang via Docker? How do I test my installation? |
| 00:35 | 3. Vector-like quark analysis with ADL/CutLang: Part 1: Analysis algorithm, histograms, local runs |
What is the general flow for the analysis?
What are the selection requirements? How do I implement additional selection requirements with ADL? How do I implement additional histograms with ADL? How do I run this analysis with CutLang? How do I produce plots comparing distribution shapes for signal(s) and background(s)? |
| 01:15 | 4. Vector-like quark analysis with ADL/CutLang: Part 2: Full analysis, shape comparisons, analysis results |
How do I produce plots comparing distribution shapes for signal(s) and background(s)?
How do I produce plots showing data, along with simulated samples of signals and SM backgrounds normalized to analysis integrated luminosity? |
| 01:40 | Finish |
The actual schedule may vary slightly depending on the topics and exercises chosen by the instructor.
