Matter Antimatter oscillations

One of the greatest mysteries of the universe is its apparent composition of only matter, and not antimatter. If matter and antimatter were created equally at the time of the Big Bang, matter and antimatter should have annihilated into pure energy. Clearly, this did not happen. How did our universe of matter survive? Particle physics experiments make it possible to observe some forms of matter oscillating into anti-matter and back. Studying such processes can help solve the mystery of the preponderance of matter in the universe. Fermilab Tevatron collides proton and its antimatter, antiproton, to produce many new particles and their anti-particles. DZero experiment detects these particles and anti-particles, and physicists study various aspects of it. One such aspect is the study of mixing of neutral B mesons from particle to its antiparticle, and vice versa. Measurement of this oscillation frequency can shed light to the matter antimatter imbalance in the universe. This book provides the details of the technique that was developed and employed to measure the oscillation frequency in the Bs system on the data collected by the DZERO experiment at the Fermilab Tevatron....
