The ATLAS Experiment Colouring Book is a free-to-download educational book, ideal for kids aged 5-9. It aims to introduce children to the field of High-Energy Physics, as well as the work being carried out by the ATLAS Collaboration.
Enjoy these free-to-download fact sheet by the ATLAS Collaboration. Explore the ATLAS detector and find more about its components, the software computing infrastructure, and the trigger and data acquisition systems. Find the Easter versions of the Fact Sheets here.
Explore educational physics "cheat sheets" developed by researchers at the ATLAS Collaboration, ideal to help with all those physics terms you want to know more about. With these sheets, you'll explore concepts from the Standard Model to conservation laws.
ATLAS Coordinate System
The ATLAS coordinate system allows scientists to accurately and consistently describe how particles travel through the detector.
Keywords: pseudorapidity
Cross Section and Luminosity
This sheet defines cross section and luminosity, presents examples of LHC cross sections, and introduces the method used to determine number of events.
Keywords: cross section, luminosity
Monte Carlo Simulation
Monte Carlo (MC) methods help ATLAS physicists simulate data by generating theoretical collisions based on both known and theorised physics. We use the simulated data to help us understand the detector’s behaviour, optimise algorithms, and identify new physics.
Keywords: model, event, signal, background
Natural Units
Our universe is governed by a handful of fundamental constants, such as the speed of light or the gravitational constant. In particle physics, it is often convenient to use natural units, in which key constants are set to unity, revealing the underlying simplicity of physical laws.
Keywords: Natural Units
Particle Decay, Lifetime & Width
The lifetime (or equivalently, the width) and the different ways elementary particles can decay are fundamental properties crucial for physicists exploring the boundaries of known physics.
Keywords: particle lifetime
Pile-Up
The LHC collides bunches (groups of protons), which can result in multiple proton-proton collisions at each crossing. Such additional collisions are called pile-up.
Keywords: background, event
Signal and Background
This sheet defines signal and background and presents some common strategies for increasing the signal-to-background ratio.
Keywords: signal, background, standard model, photon, lepton
Statistical Significance
When physicists make statements about whether or not a given process has been observed in the LHC data, they must back up their claim with strong statistical evidence. This is often expressed in terms of standard deviations or the p-value.
Keywords: standard deviation, p-value, signal, background
The Standard Model
All fundamental particles classified based on their properties! Deviations to the Standard Model can point the way to new physics.
Keywords: dark matter, standard model, higgs boson, fermion
Available in 16 languages, the ATLAS Experiment colouring book introduces kids to the field of High-Energy Physics and the work being carried out by the ATLAS Collaboration.
Learning objectives:
ATLAS scientists work together to study particles, the basic building blocks of our universe.
ATLAS scientists use a detector to find and identify particles.
The ATLAS Collaboration is diverse. Anyone can be an ATLAS scientist.
The Standard Model and the Higgs Boson.
Everything around us is made up of tiny, elementary particles. In this colouring book, kids can meet all of the particles that scientists have discovered (so far!) and learn about the role they play in our Universe.
Learning objectives:
Matter is made of tiny elemental particles.
Particles are the building blocks of all matter and are responsible for forces.
Scientists use experiments to find and study particles.
There are different types of particles with different functions.
ATLAS Activity Sheets build upon concepts introduced in the ATLAS colouring books, allowing kids to cement their new understanding of particle physics and explore all-new topics. For ease of printing, these sheets are available in colour and black & white.
