What is the new particle?

The new particle is an exotic hadron comprised of two quarks and two antiquarks. Crucially, this exotic matter particle lives longer than any other ever discovered, in addition to containing two heavy quarks and two light antiquarks, in another first.

What is the muon experiment?

Muon g-2 (pronounced “gee minus two”) is a particle physics experiment at Fermilab to measure the anomalous magnetic dipole moment of a muon to a precision of 0.14 ppm, which will be a sensitive test of the Standard Model. It might also provide evidence of the existence of entirely new particles.

How are new particles created?

When they collide, interesting things can happen. In most proton collisions the quarks and gluons inside the two protons interact to form a wide array of low-energy, ordinary particles. Very occasionally, these collisions produce new particles for us to find.

What are the 4 new particles?

The four new particles we’ve discovered recently are all tetraquarks with a charm quark pair and two other quarks. All these objects are particles in the same way as the proton and the neutron are particles. But they are not fundamental particles: quarks and electrons are the true building blocks of matter.

How Do You Measure G-2?

How do we measure g-2? A beam of muons with aligned spins is directed into a storage ring that has a very precisely known magnetic field. As the beam goes around this storage ring, the muons’ spins wobble, or precess. Scientists measure the rate that they precess very precisely.

What are the forces created by particles in the world?

They are the strong, weak, electromagnetic, and gravitational forces.

Do new particles exist?

The possibility of new particles existing is not idle speculation. Such particles might help in explaining several of the big problems in physics. Why, for example, does the universe have so much dark matter—causing the galaxies to rotate faster than we’d expect—and why has nearly all the anti-matter created in the Big Bang disappeared?

What will happen when the laws of physics are revised?

This means new particles or forces may exist that aren’t accounted for in the standard model. If this is the case, the laws of physics will have to be revised and no one knows where that may lead.

Are there still-undiscovered particles or unknown forces swirling around US?

There are still-undiscovered particles or unknown forces swirling all around us, suggest new results from a massive experiment conducted at the US Department of Energy’s Fermi National Accelerator Laboratory (Fermilab) in Illinois.

What is the Holy Grail of particle physics?

“The discovery of a new force in nature is the holy grail of particle physics. Our current understanding of the constituents of the Universe fall remarkably short – we do not know what 95\% of the Universe is made of or why there is such a large imbalance between matter and anti-matter.”
