Two new Baryons at LHC.

Two new Baryons at LHC.

Two new Baryons at LHCb.
LHCb, the famed experiment at CERN, Switzerland found a year ago two new Baryons. These are important steps in testing the validity of our state of the art understanding of current model of the Physical Universe, mostly in considering the “particle constituents” of the matter around us, and known by the name Standard Model — of Particle Physics.

Atoms with nuclei and electrons. Nucleus has nucleons in it which are two types, protons and neutrons. The protons and neutrons are Baryons with each having two different combination of 3 quarks — uud and udd.

Protons and Neutrons as Baryons, that is an eternal bond of 3 quarks. uud and udd. Note that the spring is the gluon. Much like a spring transmits a mechanical force these gluons have an assigned duty to transfer the strong nuclear forces from one participant to the other.

1. First off it does so by colliding protons with protons at gigantic speeds, at the speed of light. So these protons are 1000 times more energetic than their own mass. If you are 60 kg, your energy is 600 Joule, if you move freely a distance of 1 meter, consider yourself to be thrown so fast that you have 1000 times that energy. Both examples are approximately true.

2. Protons are called Baryons. Anything with 3 quarks in them, as we know them today are called as Baryon. The 3 quarks will never separate into single relationship status. Its a triangular love, in which each partner has their share of love meted out. Sorry particles are decidedly promiscuous. ;) And never break their relations as long as they are bonded this way.

3. These new baryons — 3 quarks in eternal bonding, are about 6 times heavier than proton. SInce protons were bombarded onto each other madly, with energies that are 1000 times bigger than their own mass, the possibility of heavier particles such as these new baryons materialized. So the protons did not break in a way quarks will cry out “I am single again” but rather go into relationships with other quarks and form heavier relationships.

The nucleus and quarks: the nucleus consists of a positive core with protons and neutrons. Each of them are baryons. A baryon is a glob of matter consisting of 3 types of quarks two of which can be same. Photo Credit: dreamstime dot com

The hinterland of particle physics

Particle Physics is collectively an effort to study the exciting world of subatomic particles and the nature of their interaction. By subatomic we mean anything that happens within the atom or below and not above. The implications could cover as much above, as it would be entailed by the precincts of natural laws.

eg If a process corresponds to as big a size as is a micro-gram, its evidently not subatomic size in length dimension. The subatomic size by its definition of length scale would correspond to a femto-meters. But the given process is subatomic, while the result of having a size of micro-gram would not be.

Hence while the size of the subatomic entity can roughly be put by a femto meter, nonetheless a particle of the size of pico-meter might find relevance in the study of subatomic processes due to such eerie connections. For another matter a micro-gram is the unit of mass and not that of magnitude of distance.
