LHC Experiments: LHC Beauty
Sunday, October 12, 2008 Labels: Large Hadron Collider, Standard Model and Forces 3 commentsThe 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 Standard Model of particle physics is a theory of three of the four known fundamental interactions and the elementary particles that take part in these interactions. These particles make up all visible matter in the universe. Every high energy physics experiment carried out since the mid-20th century has eventually yielded findings consistent with the Standard Model. Still, the Standard Model falls short of being a complete theory of fundamental interactions because it does not include gravitation, dark matter, or dark energy. It is not quite a complete description of leptons either, because it does not describe nonzero neutrino masses, although simple natural extensions do. I am a college sophomore with a dual major in Physics and Mathematics @ University of California, Santa Barbara. By the way, i came across these excellent flash cards. Its also a great initiative by the FunnelBrain team. Amazing!!!
Dear Sir:
I have been trained a physicist. If the existence exists as a delta function around "now" with uncertainty in time being zero, then corresponding uncertainty in energy is infinite. So at any "moment", existence is infinitely large. Universe expands in time because more of the future becomes available to it. Its entropy increases by tapping into the future. Hence, as more of the future becomes available to the universe, it increases the dead energy. So future "time" is the essence of energy. This "time" is the thermodynamic forward "flowing" time. The mathematical time that is used to construct the delta function is the quantum mechanical parameter. Quantum mechanics is time reversal symmetric with respect to this parameter, which has nothing to do with thermodynamic time. What is wrong with this picture? Here is my Email: hh1275@q.com,
