Event display

3.4.7. Event display#

A well-deserved pause#

In the last six lessons you built up a realistic steering file step by step. Congratulations for making it to this point! 🍰

You probably already have developed quite a nice feeling for how to work with basf2. There is much more to learn, but the remaining topics are more specialized and might not apply to every analysis.

All of the following lessons (from here out) are largely self-contained and only have prerequisites that you have already done. You can pick and choose whatever you find interesting, or whatever you think you will need.

For now though, you might be a bit tired of the whole business of steering files. So how about something a bit more visual and fun?

Meet the Belle II event display#

Head over to the The Belle II Event Display documentation pages. Take a look at the event display for the mdst file that you were looking at in these last lessons (you might need a bit of patience if you’re using xforwarding).

Exercise

Can you identify a \(B\to J/\psi K_S\) event?

Stuck? We can help!

If you get stuck or have any questions to the online book material, the #starterkit-workshop channel in our chat is full of nice people who will provide fast help.

Refer to Collaborative Tools. for other places to get help if you have specific or detailed questions about your own analysis.

Improving things!

If you know how to do it, we recommend you to report bugs and other requests with GitLab. Make sure to use the documentation-training label of the basf2 project.

If you just want to give us feedback, please open a GitLab issue and add the label online_book to it.

Please make sure to be as precise as possible to make it easier for us to fix things! So for example:

  • typos (where?)

  • missing bits of information (what?)

  • bugs (what did you do? what goes wrong?)

  • too hard exercises (which one?)

  • etc.

If you are familiar with git and want to create your first merge request for the software, take a look at How to contribute. We’d be happy to have you on the team!

Quick feedback!

Do you want to leave us some feedback? Open a GitLab issue and add the label online_book to it.
