While reading about sub-atomic particles some of us might have wondered,...
"How many types of sub-atomic particles are there in the universe?" or "Can we discover new types of particles?".
We don't know the answer to the first question yet. But the second question has a very exciting answer! For answering this question let's look at the above picture.
This picture is of the Large Hadron Collider (LHC) near Geneva. Built by the European Organization of Nuclear Reasearch (CERN) between 1998 and 2008, the LHC is the world's most powerful particle accelerator. But what is a particle accelerator?? A particle accelerator or an atom smasher is a machine that speeds up particles with the help of electric fields and forces them to collide with each other.When accelerated particles hit other particles, smaller particles come out. Normally those particles cannot be seen, but they can be seen in the particle accelerator. This helps scientists to learn more about particles and find new ones!
Perhaps the most famous discovery of LHC is the God Particle (Higgs-Boson), the particle that gives matter it's mass. Recently on 6th July, 2017 the LHC found a new particle named Xi CC++.
The LHC continues to find new particles while helping us to understand the astonishing weirdness of the quantum world.

Nice article. I want to add one sentence to the above article:
We cant detect the some particles in the normal labs because of their very very small life time. so we have to expand their life time. Trick is that according to Einstein's theory of relativity, time slows down when we approach to the speed of light. Thus particles born in highly accelerated conditions have more life time than in normal conditions. so we can detect them.

i thought its protons and neutrons that give matter mainly its mass. whats the role of god particle in mass?

Yes, Mr. Prashant your perception is partly correct. Even the mass of proton or neutron is due to God particles.
The Higgs boson particle is so important to the Standard Model because it signals the existence of the Higgs field, an invisible energy field present throughout the universe that imbues other particles with mass.
