Questions

• How well do you understand what we covered?

Objectives

• To review…

Let’s review some of the concepts we covered in the previous episodes. You are encouraged to go back and engage with those episodes in order to answer these questions.

You can post questions on the Mattermost channel for this exercise.

Let’s review!

Can you get to the starting page for the CMS Open Data Portal? Can you select the CMS data from that page?

Let’s review!

The bulk of the CMS released data covers what years? What was the collision energy for those years?

Let’s review!

What’s the difference between Collision data and Simulated data?

Let’s review!

Select the CMS collision data for 2015. Select only the MINIAOD data. Do you remember what the MINIAOD data are?

Choose one dataset and identify different triggers that were used to direct events in this dataset. What do you think they are triggering on?

Let’s review!

Select the CMS simulated data for 2015. Select the Heavy Gauge Bosons (under Filter by category) and find a Wprime sample. Click on it. These are hypothetical gauge bosons.

How can you learn about CMS simulated dataset names? What do you think the W’ is decaying to? What is the assumed mass of the W’ in this particular sample?

How many events are in this sample? How much hard drive space does this sample occupy? Can you find the generator parameters that were used to generate the collisions?

Key Points

• The information is all there for you to find datasets you want for your analysis.

• But it make take some poking around to find it.

• Familiarizing yourself with the search options is time well-spent.
