LHC Experiments: LHC Beauty

The Experiments Dedicated to Quark Gluon's

Most focused and elegant of all the six experiments at the LHC is the LHC beauty or LHCb. It will try to find asymmetries in the behaviour of B-Quark and anti-B-quark particles.
Oh then what is quark, B-Quark and the lack of symmetry. What will they signify.
The present model of particle physics, Standard Model, envisages that Proton and Neutrons are made-up of fundamental particles called Quarks. Each ordinary run-of-the-mill proton or neutron is made of two types (Pair) of Quark - UP Quark and Down Quark. Three quarks (two of one type and one of another) make a Proton or Neutron.
Quarks inside the Proton/Neutron are held together by force particles called Gluon's.
Surprisingly there are Two other family of pair of Quarks. These are named exotically as seen in graphic above. Surprising part is that all the matter that we see in the world is made of Up/Down family of Quarks. Quarks of other two families are very short lived. Where has the matter made of other two Quark families disappeared. The Top & Bottom Quarks were at one time also called Truth and Beauty. Together this family is called B-Quark Family.
Quarks have a property that they cannot be seen by themselves - but only as a Quark-Gluon Plasma. Its this Plasma -specially B-Quark family - that will be targeted at the LHCb.
But what will it signify. And what about the Symmetry?
That will be the next post.

The Animation Of Proton Movement in LHC

Zipping The Beam
Please see my post on how two counter rotating beams of proton are accelerated in stages and then collided. Remember the rings smallest to largest are:
1.Booster Ring on Surface
2.Proton Synchrotron on Surface
3.Super Proton Synchrotron at 40M below level
4.LHC with ATLAS at 100M below.

Likely Progression of LHC Experiments Over Next Two Decades

As The Years Go By LHC Will Become Wiser

ALICE Expriment
As Mentioned earlier, there are four sets of Detectors on the LHC Ring Tunnel - ALICE, ATLAS, CMS & LHCb. Since ATLAS & CMS only crosscheck each other, there will be only three sets of results. How will the results of these experiments improve with time?
The results from particle collisions, like any other quantum affected processes, are based on probabilities. Therefore confirmations of results will have to wait for accumulation of enough numbers of collisions.
As with passage of time, the teething trouble will be overcome and the learning curve in running the LHC will be crossed, the number of possible collisions per year will grow from 6X1013 in 2009 to 6X1015
in 5 to 6 years time (2014)- a 100 time increase . The more energy you have in LHC the more heavier particle it can detect. Depending on the promise that LHC unfolds, it may then be shutdown for an upgrade to increase its power from 14TeV to 40TeV and also to larger number of collisions per year to 6X1016 a further 1000 times increase.
So up to 2014 before the upgrade we will be discovering only lighter particles but more and more particles are likely be confirmed as the year go by till then.
After upgrade the higher particles are likely to be confirmed in 4 to 5 years thereafter (2018-2019).
Hmmmm!! But what will these particles that we expect to look for - That will be next post Sir!
