Unveiling Hidden Physics at the LHC using Open Data

Making particle physics Open Data usable

Clemens Lange
<p>The experiments at the Large Hadron Collider (LHC) at <a href="https://home.cern/">CERN</a> have been running for more than a decade. The data recorded by the detectors such as the <a href="https://cms.cern/">CMS experiment</a> are analysed by thousands of physicists all over the world. The CMS Collaboration has made openly available more than 2.5 petabytes of data on the <a href="http://opendata.cern.ch/">CERN Open Data Portal</a>, containing billions of recorded and simulated events.</p> <p>Open Data are, however, only useful when accompanied by realistic usage examples. The sheer amount of data as well as the fact that the software used to analyse them is often more than ten years old poses several challenges. In this presentation, Clemens will discuss how the CMS Data Preservation and Open Access group tries to overcome these challenges so that potentially everyone could use the data to <a href="https://arxiv.org/abs/2109.06065">unveil hidden physics</a>.</p>

<p>This presentation is about the development and trajectory of Heurist (HeuristNetwork.org), a shared, integrated, extensible data infrastructure (model, build, manage, analyse, visualise, share, publish via integrated CMS) for Humanities research capable of handling the needs of many heterogeneous projects on a single standalone service*, with optional integration across multiple servers by a coordinating index (itself based on Heurist).</p> <p>Humanities data are interesting (both technically ...

<p>Developed from 1995 onward, Prospero is a framework for longitudinal analysis of text corpora. Based on dictionaries and semi-automatic classification, it mainly allows its user to combine approaches of statistical computation, co-occurrence network and search for nested patterns. Inspired by pragmatic sociology, it focuses on the multiple forms of expression and argumentation used by actors, on language regimes and on the identification of transformations occurring in the research case. ...

<p>I am a social scientist who mostly teaches and conducts qualitative research, but I am also a programmer. Over the years, I have contributed to a variety of free and open source software projects, and since 2019, I have developed and maintained <code>textnets</code>, a Python package for text analysis that represents collections of texts as networks of documents and words, providing novel possibilities for the visualization and analysis of texts. In my field, such software development efforts ...

<p>The writing of web publications mixing data visualization and textual prose opens novel opportunities for connecting evidence, arguments and narrative in social sciences communities. Such a practice poses a variety of challenges in terms of website design and development ; but also and maybe more importantly, it asks for experimenting specific workflows for coordinating a variety of expertises ranging from social sciences disciplines (history, sociology, etc.) to data science, information ...

<p>This talk will show a new Python tool called Livemark, which is designed for data journalism software education, and documentation writing. Using Livemark, you can collect and present data with interactive tables, charts, and other elements without leaving a text editor. You can also write documentation with live script execution similar to a lightweight version of a Jupiter Notebook. This talk will demo Livemark and will be well-suited for a technical and non-technical audience that is ...
