Electron + Positron to two quarks and a gluon

Two protons colliding.

Complex Higgs boson signal for ATLAS experiment article

Two quarks (solid lines) and a gluon (curly line) fly apart, with the strings (red bars) primarily between the gluon and each quark.

As a result, three jets (cones) form, with extra hadrons (arrows) found where the strings formed.

For comparison, physicists looked at events with two quarks and a photon (wavy line). Here the string forms only between quarks.

Therefore extra hadrons are found only between the two jets.

The main barrel section of the ATLAS hadronic calorimeter, waiting on September 27, 2005 to be moved inside the toroid magnets. (A piece of one of the magnets, with orange temperature-sensing stripes, can be seen in the upper left.)

A large experimental hall at the Intersecting Storage Rings particle accelerator at CERN. The accelerator is beneath the hill that can be seen connecting to the building on the left side. The building itself is now used as part of the magnet-fabrication process for the Large Hadron Collider.

Some of the buildings associated with the Intersecting Storage Rings particle accelerator at CERN. The accelerator itself is beneath the curved, tree-covered "hill" that runs around the outside of the road.

The surface above the Proton Synchrotron particle accelerator at CERN. With more than 45 years to be evened out, have buildings built around it, etc. the ring-shaped hill containing the accelerator is not completely obvious--but it can be seen curving around on the left side of the image.
