Particle Collision Crewneck Sweatshirts

Have you had an accident at work? Call the particle collision helpline. A design with an illustration showing two particles colliding as they do at CERN's large hadron collider.

Streamer chamber photo of an oxygen ion collision in the NA35 experiment at CERN, the European particle physics laboratory outside Geneva. The oxygen ion has collided at left with a nucleus of lead, producing a spray of particles that shoot out towards the right- hand side of the chamber. One particle is a low- energy electron which spirals inwards in the chamber's magnetic field, its track growing more dense as it loses energy.

Artificially coloured bubble chamber photo from CERN, Geneva, showing the tracks of subatomic particles; details of particles unknown. (1984)

Bubble-chamber photograph of particle tracks from a cosmic ray collision.

Higgs boson. Computer artwork showing a Higgs boson particle, which was formed by the collision of two protons, decaying into two photons. The Higgs boson is thought to give other particles mass. The first sighting of it was announced by scientists at CERN on 4th July 2012.
