1 ATLAS Questions and Answers John Rominger-Watts PHYS 129, Fall 2010
2 Questions: - What is mass? - Why is gravity weak compared to the weak force? - Does dark matter exist? - Why is the universe mostly matter, not antimatter? - Is supersymmetry real? - What does the top quark look like? - How did the universe behave at the Big Bang?
3 Answers: We have some... - (Supersymmetric) String theory - Higgs mechanism - CP violation - Other modifications to Standard Model but how do we know if they're right?
4 Large Hadron Collider - Replaced the outdated Large Electron-Positron collider (LEP) - Can accelerate protons and lead ions - Currently the largest and most powerful particle accelerator
5 ATLAS - One of six main detectors - ~2000 scientists/engineers - Involves 35 countries - 44 m long, 25 m diameter - Weighs 7000 metric tons - Detected first events in 2008
6 ATLAS Detector Systems Inner Detector:
7 ATLAS Detector Systems Calorimeter:

9 Question: What is mass? - Inertial mass: resistance to acceleration Image: nasa.gov Image: sparknotes.com - Gravitational mass: attraction to other massive objects Image: mit.edu Image: toothpastefordinner.com
10 Answer: The Higgs Mechanism (maybe) - Predicted by the Standard Model - Explains why photons are massless, but W and Z bosons aren't - Uses spontaneous symmetry breaking to give W and Z bosons mass - Can detectably manifest as a Higgs boson
11 The Higgs Mechanism As explained by Prof. David Miller, University College London: - Evenly-distributed politicians - Politicians gather around an important figure or or - Higgs field permeates all space - The field is distorted by a moving particle Images: David J. Miller
12 The Higgs Boson As explained by Prof. David Miller, University College London: - Evenly-distributed politicians - People crowd around the source of a rumor or or - Higgs field permeates all space - A wave of Higgs field clustering propagates Images: David J. Miller
13 Cool! So, where is the Higgs? We've been searching through every energy range accessible... ATLAS can look in the unexplored regions! Directly: when combined with other particles, can form an almost unique decay signature Indirectly: can measure corrections to W and Z bosons caused by Higgs loops Images: wikipedia.com
14 And if we're wrong? Image: xkcd.com
15 And if we're wrong? ATLAS should confirm or deny some other theories... - Technicolor: - New gauge interaction coupled to technifermions - Extra dimensions - Kaluza-Klein Theory (1923) - Top quark condensate: - Replaces Higgs field with bound top and antitop quarks
16 So, what about the top quark? Image: FNAL - Recently discovered experimentally (Fermilab, 1995) - The heaviest elementary particle observed so far - Bare mass around 171 GeV/c², comparable to a tungsten nucleus - Difficult to produce and measure because of its mass
17 Question: Why is the universe matter? (Rather, why is it not antimatter, too?) We have two options: 1.) The universe was imbalanced from the beginning 2.) The universe can produce matter and antimatter at different rates - To do this, Sakharov (1967) says we must: - Not conserve baryon number (not observed) - Break CP symmetry (observed) - Not have thermal equilibrium (OK, but slow)
18 Answer: CP violation (maybe) Here's the problem: the Standard Model allows two types of CP violation - Strong interactions: - Never been seen experimentally - Would make neutron EDM ~10^-18 e*m! (exp. < 10^-28 e*m) - Would be much too large - Weak interactions: - Seen experimentally - Not enough violation!
19 Seeing CP violation in the LHC LHCb (CERN) Tevatron (FNAL) - Directly: detection of new particles - Indirectly: B-meson oscillation (LHCb) - Bº mesons transform into their antiparticles and back - Decay into matter 1% more than antimatter (FNAL, 2010)
20 Review and Conclusion: ATLAS is poised to unveil many mysteries of the universe: - Higgs boson and the origin of mass - CP violation and the origin of the universe - The top quark as a stepping stone

ANTIMATTER MATTER. does the difference between matter and antimatter arise?
WHY ANTIMATTER MATTERS! One of the most striking facts about the Universe is that it is composed almost entirely of matter. At the Big Bang equal amounts of matter and antimatter would have been created.
