pyhf v0.7.1 is also the first release to have project updates make it into the NumFOCUS monthly newsletter. :) numfocus.salsalabs.org/numfocus__news… Looking forward to sharing many more future updates with everyone!

If you’re going to be at #SciPy2023 or #PyHEPdev2023 and would like a pyhf - python HistFactory sticker come find me to chat!

pyhf v0.7.3 is out on PyPI and Conda-forge! github.com/scikit-hep/pyh… This patch release has a bug fix for handling specific configurations of iminuit optimizer strategies. Upgrade today! python -m pip install --upgrade pyhf

Congratulations to Belle II Experiment on this beautiful analysis and exciting result!

B̅→K̅νν̅ is a prime target for RECAST-like reinterpretations. Danny van Dyk 🇪🇺 explains in more detail in this thread our work in that direction and Lorenz will give a talk later today. Including new pyhf - python HistFactory features, which were developed by Malin Horstmann within our group in Munich

pyhf v0.7.4 is out on PyPI and Conda-forge! github.com/scikit-hep/pyh… This patch release has a niche bug fix for safeguarding repeadted invocations of pyhf.set_backend before garbage collection can occur. Upgrade today! python -m pip install --upgrade pyhf

We are pleased to announce the inaugural #pyhf Users and Developers Workshop will take place at CERN 4 - 8 December, 2023! indico.cern.ch/event/1294577/ Registration and call for abstracts are open now, so register today!

Belle II reported the first evidence for the rare "missing energy" decay B → K νν̅ at the #EPSHEP2023 conference this summer. Now our journal paper describing the analysis has appeared on arXiv.org, arxiv.org/abs/2311.14647

It warms my heart that our little tool pyhf - python HistFactory seemed useful for such a result ❤️

Today's the day! The 2023 #pyhf Users and Developers Workshop begins at CERN at 10:00 CET! We're looking forward to a great week of community interaction, discussion, and development. 🚀 indico.cern.ch/e/pyhf-worksho…

And we’re off with i am on bluesky giving a brief overview and tutorial of #pyhf. indico.cern.ch/event/1294577/…

Now we’re moving on to an overview of cabinetry from Alexander Held! indico.cern.ch/event/1294577/…

Closing out the morning session we have a talk from Vangelis showing how ATLAS SUSY searches are using #pyhf and cabinetry for analysis! indico.cern.ch/event/1294577/…

Tomorrow morning (8:30 CT on Tuesday) I'm going to be giving a personal retrospective about some of the statistical tools we developed for the LHC and the thriving community around pyhf - python HistFactory indico.cern.ch/event/1294577/…

Talk on "HEPData and pyhf - python HistFactory" at the #pyhf Users and Developers Workshop this morning: indico.cern.ch/event/1294577/…

Delayed in posting, but a great and busy second day of the #pyhf Users and Developers workshop with excellent contributions from HEPData, Belle II Experiment, MicroBooNE, SModels, Jack Araz, Kyle Cranmer and more! indico.cern.ch/event/1294577/…

pyhf v0.7.6 is out on PyPI and Conda-forge! github.com/scikit-hep/pyh… This patch release has small bug fixes around the JAX backend support across multiple versions, small bugs squashed, and improved user warnings. Upgrade today! python -m pip install --upgrade pyhf

Rowan Cockett 🦋 MyST Markdown Lorena Barba @[email protected] @stevejpurves Chris Holdgraf So from taking the MyST Quickstart and just messing around we've gotten to the point where I think I see a clear path to a super powered blog with JupyterLite. (Got pyhf - python HistFactory in there by taking a jupytext py:percent notebook, converting during CI, and then using piplite inside)

It was wonderful to have Kyle Cranmer give such a fantastic keynote at #SciPy2024! He covered a story more than 20 years in the making and one that is continuing through strong community investment! :D I can’t wait to share this with everyone once the recording is up on YouTube.

pyhf is an open source, pure-Python library that implements statistical modeling and inference techniques commonly used in particle physics. It was developed by partners at DSI, TU München and UC Santa Cruz. Get the source code and other documentation: dsi.wisc.edu/tools/pyhf/
