Who discovered X17?
The exciting new particle, which has been billed as a ‘no-brainer Nobel prize’, was discovered by the scientists as they studied how an excited helium atom emitted light as it decayed. It is the second time that lead scientist Attila Krasznahorkay and his team had witnessed the new particle they called X17.
Is there a fifth force of nature?
Now, physicists say they have found possible signs of a fifth fundamental force of nature. The UK’s Science and Technology Facilities Council (STFC) said the result “provides strong evidence for the existence of an undiscovered sub-atomic particle or new force”.
Is X17 real?
But when upgrades to the LHC are complete in the next year or so, scientists plan to use the Large Hadron Collider beauty (LHCb) experiment, which studies another particle known as the beauty quark, to see if the mysterious X17 turns up.
How do you describe a particle?
Definition of particle 1a : a minute quantity or fragment. b : a relatively small or the smallest discrete portion or amount of something. 2 archaic : a clause or article of a composition or document. 3 : any of the basic units of matter and energy (such as a molecule, atom, proton, electron, or photon)
Is there another force?
But new evidence suggests the existence of a fifth force of nature, which could open a whole new understanding of the laws of physics. The forces currently known to scientists are gravity, electromagnetism, the weak force and the strong force.
What is a particle theory?
The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.
What is represented by the particles?
Particles are often represented as dots. This figure could represent the movement of atoms in a gas, people in crowds or stars in the night sky.
