Particle Collisions on Quark and Gluon level

Discover the intricate dynamics of particle collisions at the quark and gluon level in this insightful presentation by Erik Johansson from Stockholm University. Delve into gluon exchanges, quark-antiquark annihilation, and the production of fundamental particles like Higgs and Z bosons. This animation series, each around a minute and a half, simplifies complex concepts without Lorentz contraction or virtual loops, making advanced physics accessible. Join us in unraveling the fascinating world of high-energy physics and the behavior of quarks and gluons in particle collisions.

  2. QUARK AND GLUON COLLISIONS • Dynamics • Gluon exchange • Gluon fusion • Quark-antiquark annihilation • Quark and gluon interactions • 4 jets – hadronisation • Higgs particle production • Decaying to ZZ • Decaying to gg • Top-antitop production • Decaying to almost every quark and lepton • Z particle production • Decaying to an electron and a positron Erik Johansson

  3. PHYSICS IN ABOUT A MINUTE • Physics in a minute • Each animation is about a minuteand a half long • About 70 MB HD (QuickTime, H264 compact.) • Simplifications • No Lorentz contraction • No virtual loops • Start with the proton • A complex object Erik Johansson

  4. ONE EXAMPLE (SECOND EDITION) • Higgs production • Gluon-gluon fusion (without top loop) • Decay to ZZ decaying to leptons • The decay to gg also done • First edition: • http://www.physto.se/~kej/animations/ Erik Johansson
