First detection of 

exotic 'X' particles in 

quark-gluon plasma

Date Posted: 25th January 2022



Physicists have found evidence of X particles in the quark-gluon plasma produced in the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research, based near Geneva, Switzerland.

In the first millionths of a second after the Big Bang, the universe was a trillion-degree plasma of quarks and gluons - elementary particles that briefly glommed together in countless combinations before cooling and settling into more stable configurations to make the neutrons and protons of ordinary matter.

I will be talking about quark-gluon plasma in my blog; however, for now, you can understand that a millionth of a second after the Big Bang, the universe was an incredibly dense plasma, so hot that no nuclei nor even nuclear particles could exist. The plasma consisted of quarks, the particles that compose nucleons and some other elementary particles, and gluons, the massless particles that “carry” the force between quarks.
 
(Read my latest article - Introduction to Standard Model for an introduction to these particles!)

In the chaos before cooling, a fraction of these quarks and gluons collided randomly to form short-lived "X" particles, so named for their mysterious, unknown structures. Today, X particles are extremely rare, though physicists have theorized that they may be created in particle accelerators through quark coalescence (the joining or merging of elements to form one mass or whole), where high-energy collisions can generate similar flashes of quark-gluon plasma.

    Table of contents  WHAT ARE  QUARKS, LEPTONS  AND  BOSONS? View my previous article here - How were Neutrinos Discovered? View the next article here - The Fundamental Forces ----------------------------------------- Here is a brief overview of what are quarks, leptons and bosons - families of particles that make up the Standard Model! (Based on what has been discussed so far).  * ADDITIONAL * -  A fermion is any particle that has an odd half-integer (like 1/2, 3/2, and so forth) spin.  Quarks  and  leptons , as well as most composite particles, like  protons  and  neutrons , are fermions. QUARKS: Quarks are subatomic particles that are found in protons and neutrons in the atomic nucleus. There are 6 quarks .  Up quark and Down quark belong to the first generation. Charm quark and Strange quark belong to the second generation. Top quark and Bottom quark belong to the third generation. The second and third generation particles are more massive and unstable when compared to the

Table of contents   PARTICLE PHYSICS - INTRODUCTION View the next article here - More on Particle Physics and Why it matters? ----------------------------------------- What is Particle physics? Let me give a hint by telling you what particles are? Everything in our universe is made up of extremely small components known as particles. Now did you get it? Particle Physics is nothing but the study of how our universe was made and what our universe is constituted of. To prove their existence and see how they behave, scientists observe them until the particles leave a sign. Often, instead of waiting for the particles to leave a sign, they make particles by colliding known particles. How? Well, the accelerators speed up the known particles almost to the speed of light. The particles collide and release massive energy, which results in the creation of new particles. This is why Particle physics is also known as High Energy Physics . At present, there are 17 particles that have been identifie

    Table of contents  GLUONS View my previous article here - Introduction to Quantum Electrodynamics and Quantum Chromodynamics View the next article here - Introduction to Feynman Diagrams ----------------------------------------- Just like how electrons carry the electric charge, the quarks also carry the electric charge, but this electric charge is weaker in quarks. Quarks additionally carry a coloured charge , as discussed in the previous article . This coloured charge generates a gluon force field. An accelerating quark creates a vibrating ripple in the gluon field, which is known as gluons. Just like how a photon can create an electron and positron (anti-electron) pair - energetic gluon can create a quark and antiquark pair - While the electromagnetic charge has only one version, the colour charge has 3. But the colour charge never shows up in the hadron quark combinations. (Keep reading to find out about hadrons.) This led to the idea that the three colour charges were red, yel
