Updated particle Collisions onQuark and Gluon level Erik Johansson Stockholm University ATLAS week Montreux 2012
Quark and Gluon Collisions • Dynamics • Gluon exchange • Gluon fusion • Quark-antiquark annihilation • Quark and gluon interactions • Higgs particle production • Decaying to ZZ • Decaying to gg • Top-antitop production • Decaying to almost every quark and lepton of the Standard Model • Z particle production • Decaying to an electron and a positron
Physics in about a minute • Physics in a minute (or two ... or three) • Each animation is about a minute and a half long • About 80 MB HD (the double for top-antitop) (QuickTime, H264 compact.) • Simplifications • No Lorentz contraction • No virtual loops • Start with the proton • A complex object 3
ONE EXAMPLE – ONE OF THE MOST COMPLEX On atlas.ch (thanks to Paul Schaffner)
In the pipeline • Update of four jet production – hadronisation • A bit of a challenge • Article ”Exploring Quarks, Gluons and the Higgs particle” to appear in Physics Education explains the physics a bit more in detail.
