Discovery or Glitch? (02:29)
Scientists visited Chicago to hear particle physicists from CERN to learn the latest news from the Hadron Collider. Rumors circulated that they discovered new matter. Horizon will examine the few months where teams attempted to discover if it was a glitch in data or the biggest physics discovery in modern times. (Credits)
Large Hadron Collider (03:21)
Particle Physicists believed the LHC created a new subatomic particle that would transform physics. Mike Lamont performs maintenance on the world's largest particle collider, which was built in 2009. Super conducting Magnets bend the beam inside the accelerator.
Finding New Particles (02:44)
The LHC recreates conditions a millionth of a second after the big bang. Dr. Victoria Martin examines how to use mass-energy equivalence to explain how the particle accelerator works. Physicists hope that undiscovered particles will explain how the universe was formed.
Detecting Particles (03:34)
Dave Charlton runs A Toroidal Large Hadron Collider Apparatus (ATLAS) and Tiziano Camporesi runs the Compact Muon Solenoid (CMS). The two physicists discuss how it detects particles from the LHC's experiments and the two machines can corroborate and validate findings.
Everything Made From Atoms (04:05)
James Gates, Jr. explains the Standard Model of Particle Physics including the discovery of leptons, muons, gluons, quarks, and neutrinos. Fermions interact through force carriers. The Higgs boson gives particles mass.
Evidence of a New Particle (03:50)
In November 2015, Dr. Livia Soffi discovered some unexpected data from the CMS, indicating the experiment was producing more photons than anticipated. Using ATLAS, James Beacham corroborated the data. CERN presented their findings on December 15th.
Gathering More Data (04:57)
Both CMS and ATLAS work independently to reach 5 Sigma, a level of statistical certainty. CERN wanted to announce at the Chicago conference in a few months if they discovered a new particle. Dr. Gian Giudice describes what they hoped a new particle would reveal and how the Standard Model of Particle Physics cannot accurately explain the universe.
Making a Breakthrough (03:06)
Dr. Magda Chelstowska describes her job description at ATLAS. Dr. Marco Delmastro double-checks all the data to make sure nothing is left to chance.
Super Symmetry (06:01)
Gates describes how the Super Symmetry Model explains how the universe was created, incorporating the Standard Model of Particle Physics. Virtual Particles pop into existence and then disappears. Using a teapot and stack of coins, the physicist describes the quantum vacuum and how super symmetry stabilizes the universe.
Unexpected Delays (02:30)
The Proton Synchrotron (PS) short circuited and now the LHC cannot operate. The Rotating Machine, its power supply, was built in 1967.
Extra Dimensional Graviton (03:55)
Dr. Raman Sundrum hopes that the proton bump is a hypothetical force carrier particle. Electromagnetism is stronger than the force of gravity. The physicist explains his theories by using a blade of grass and an insect.
ATLAS' Conclusions (02:51)
Delmastro reveals ATLAS' findings during a team meeting. CMS cannot discover their conclusions until they complete their research. They could not duplicate the increase in protons.
CMS' Findings (03:14)
CMS also experiences no increase in protons. Dr. Camporesi informs the team during a group meeting.
At the Conference (04:35)
Camporesi and Charlton attend the CERN conference in August and share their findings with the public. Physicists react to the news and describe their hopes for the future.
