Charm and Strange Beauty

At the Large Hadron Collider (LHC) you may have heard they are looking for the particle called the Higgs-Boson. This particle is predicted by the Standard Model in particle physics. It is the only particle predicted in the Standard Model which has not been observed in experiments up to the present day. The LHC is not alone. The particle accelerator, Tevatron, at Fermilab, has also been looking for the Higgs-Boson but at lower energy levels than those at LHC. The Higgs-Boson, if found, will help explain the reason particles have mass.

What you may not have heard about is the experiment at LHCb. This massive experiment-

is not about mass– it sets out to investigate what happened prior to 1 second after the big bang.

CERN describes the experiment for laymen saying-

Fourteen billion years ago, the Universe began with a bang. Crammed within an infinitely small space, energy coalesced to form equal quantities of matter and antimatter. But as the Universe cooled and expanded, its composition changed. Just one second after the Big Bang, antimatter had all but disappeared, leaving matter to form everything that we see around us — from the stars and galaxies, to the Earth and all life that it supports.

An important step along the way is finding the particle called “Strange Beauty”, composed of a quark and an anti-quark. This has been accomplished as of May 7th, 2010. The LHCb physicists have collected about 10 million proton-proton collisions in order to find this first Beauty Particle. The reconstruction of each event is not easy, there are about 100 particle tracks reconstructed in this event.
