What are Hardons in Particle Physics #Physik_World

Hardons



Hardons are the composite particle; means particles that are made of more than one quark. Hardons are sub-divided into two types of particles called Baryons and Mesons. 



Baryons:

Proton and Neutron are known as baryons; means that they are made of exactly three quarks. Baryons are in the family of Hardons, which means that they are made of quark.


NOTE: Composite Fermions(especially 3 quarks) in which case they are called baryons. Baryons are called composite fermions because it follows Pauli exclusion principle (half-integer spin).

Mesons:

The only other subcategory of Hardons is Mesons, which are made of one quark and one antiquark.
NOTE: Composite bosons(especially 2 quarks) in which case they are called meson. Mesons are called composite bosons because it doesn't follow Pauli exclusion principle.(Thus have integer spin and called composite bosons).

What is Particle Physics ? You see everywhere there is patterns in the universe but if you travel inside it; you will see small particles rather than big things i.e. universe itself. So, the branch of physics that deals with the small fundamental particles is called particle physics. Particle physics studies the sub-atomic particles inside an atom. Fundamental particles means not regarded as made up of other particles like electron. But what about proton and neutron ?  Proton and neutron are elementary particles. Elementary particles means which can be sub-divided into other particles. All matter around us is made of elementary particles, the building block of matter. These particles occur in two basic types called quarks and leptons.

What is Quantum? #Physik_World

What is QUANTUM? You see light, if you zoom it you see particles these particles is associated with different energy each quantum/energy is directly proportional to the frequency of the radiation i.e. E=hv means energy of photon. Ɣ Gamma Represents Photon (Symbol) As we know photon is the particle of light, but why? It has no mass too. But it travels at the speed of light. This is quite wired for understanding. Here's the question come's if mass-less particle can travel at the speed of light "photon". What about those particle which has mass and the answer is "no" particle having mass can't travel at the speed of light. Why ? Because it needs infinite amount of energy to do so. Now, you may ask why infinite amount of energy is required. It is due to increment of mass due to increment of speed. So it needs more and more energy to push it up.
