TITLE:

What’s the Matter With Antimatter?, 49 pages (slides)

SLIDE TOPICS, SUBTOPICS and CONTENTS:

What’s the Matter With Antimatter?
Dr. Natalie A. Roe
Lawrence Berkeley National Laboratory
The Prediction of Antimatter1900 - 1920’s: Development of relativity, quantum mechanics
1928: Paul Dirac’s relativisitic equation of motion for the electron
Predicted the positron, antimatter partner of the electron
Predicted that negative protons must also exist
Speculated that half the stars may be made of antimatter
The Discovery of Antimatter
The positron was discovered in 1932 in cosmic rays by Carl AndersonWhat is a Fundamental Particle?Quirks of quarks …
Two types of quarks are needed to make our world, “up” and “down”
proton = (uud) and neutron = (udd)
protons and neutrons form nuclei
add electrons to form neutral atoms
neutrinos are emitted in nuclear processes that power the sun
4 fundamental particles are building blocks of our world
Discovery of the Anti-proton at Berkeley Lab in 1955
Antimatter Production in the Sun
Every second, thermonuclear reactions in the sun convert 600 million tons of hydrogen into 595 million tons of helium, and 5 million tons of mass is converted to energy
p + p => pn (deuterium) + e+ + n
pn + p => 3He + g
3He + 3He => 4He + p + p
Solar flares accelerate particles, producing electron-positron pairs.
~ 0.5 kg antimatter produced in large flare!
Image of flare by RHESSI satellite (PI Bob Lin of UC Berkeley/SSL)Where is all the Antimatter?
No antimatter within our galactic cluster
Can Universe be a quilt of matter & antimatter domains?
Gamma ray spectrum in space rules out antimatter domains smaller than ~1000 Mpc No evidence yet for antimatter in primordial cosmic rays
Symmetries of Matter: C, P and TC = Charge conjugation: particle ?antiparticle P = Parity (mirror reflection): x ? -x C and P together change matter to antimatter;
T = Time reversal: t ? -t
The product CPT: always invariant!!!1957 Discovery of Parity Violation
Another way to look at CP Violation
An Unexpected Discovery In 1964
CP Violation => T Violation unless CPT is also violated!The Asymmetric B Factory ConceptRecipe for Measuring CP Violation in B Meson Decays
Produce many B0 B0 pairs (hundreds of millions)
Reconstruct one B in a special decay called a CP eigenstate
“Tag” the other B0 to make the matter/antimatter distinction
Determine the time between the two B0 decays, Dt
Compare Dt distributions for B0 and B0 tagged events; the difference measures CP violation, the difference between matter and antimatterTracking Charged Particles in the SVTWhat does this result mean?
Maximum asymmetry => sin2b = 1
Zero asymmetry => sin2b = 0
Much larger asymmetry than in K0 decays (72% vs 0.2%); combined experimental plus theoretical error is small
The result is consistent with the prediction of the three-generation Standard Model
What is the Matter with Antimatter?
How can a parameter between 0 and 1 provide the missing 10 orders of magnitude?
It can’t
New particles can provide the required CP violation
The effects of new particles may be observable in B decays…World average for sin2b in “penguins” compared to J/Y Ks
Future Prospects for BaBar…
The BaBar experiment has published ~ 150 papers so far in refereed journals on a wide variety of topics
Expect to collect ~4x more data over next 3-4 years => statistical errors will decrease by x2
In a race with the Japanese B Factory
behind right now in total luminosity
advantage in the ability to confirm any unexpected results
The Large Hadron Collider at CERN will turn on in 2007, data taking by 2008
could directly produce new particles
Summary
CP violation is required in any theory starting from the Big Bang to explain the dominance of matter over antimatter
The Anti-Hydrogen Economy?
Distinguish between energy source and method to store and transport energy -
Creating, storing antiprotons requires a lot of energy, and trapping them is also very inefficient
All the antiprotons created in one year at Fermilab would only power a 100 watt bulb for 30 minutes, even with 100% trapping and conversion efficiency!
Cost: $62.5 trillion per gram!
What really happens in beta decay?
CP was still OK!!
The Force Carriers
Quarks and leptons interact via four different types of forces, each with its own force “carrier”
electromagnetism - the photon, g
strong force - the gluon, g
weak force - the W± and Z bosons
gravitational force - the graviton?
What’s the Matter with Antimatter?
Our present view of matter - the “Standard Model” of particle physics
The amazing prediction and discovery of antimatter
Is antimatter useful, Dr. Spock?
Colliding matter and antimatter
What happened to all the antimatter ? - the search for CP Violation
Why does it matter?First Observation of CP Violation in B Decays - Announced July 6, 2001
