The answer may lie at CERN, where scientists create antimatter by smashing protons together in the Large Hadron Collider LHC , the world's biggest, most powerful particular accelerator. The more energy the LHC produces, the more massive are the particles—and antiparticles—formed during collision. It is in the debris of these collisions that scientists such as Ivan Polyakov, a postdoc in Syracuse's HEP group, hunt for particle ingredients. HEP is renowned for its pioneering research into quarks— elementary particles that are the building blocks of matter. Each pair has a corresponding mass and fractional electronic charge.
Despite its relatively high mass, a charmed quark lives a fleeting existence before decaying into something more stable. Recently, HEP studied two versions of the same particle. One version contained a charmed quark and an antimatter version of an up quark, called the anti-up quark. The other version had an anti-charm quark and an up quark. Using LHC data, they identified both versions of the particle, well into the tens of millions, and counted the number of times each particle decayed into new byproducts.
Adds Polyakov, "Particles might look the same on the outside, but they behave differently on the inside. That is the puzzle of antimatter. The idea that matter and antimatter behaves differently is not new. Previous studies of particles with strange quarks and bottom quarks have confirmed as such.

What makes this study unique, Stone concludes, is that it is the first time anyone has witnessed particles with charmed quarks being asymmetrical: "It's one for the history books.

Home Physics General Physics. March 21, A CP-symmetry transformation swaps a particle with the mirror image of its antiparticle. The LHCb collaboration has observed a breakdown of this symmetry in the decays of the D0 meson illustrated by the big sphere on the right and its antimatter counterpart, the anti-D0 big sphere on the left , into other particles smaller spheres.
The extent of the breakdown was deduced from the difference in the number of decays in each case vertical bars, for illustration only. Credit: CERN. Explore further.

This decay is forbidden in the Standard Model of particle physics and therefore its observation would indicate a discovery of "new physics", which is now the key goal of the LHC. It provides precise predictions for measurable quantities that can be tested experimentally. Even with charm, strange, and bottom quarks all showing asymmetry, it's not enough. The only known fundamental scalar particle is the Higgs boson with a mass of GeV.

Mar 21, A better title "physicists reveal the current reason why they believe matter dominates the universe".
Because the reason will change, it is a belief. Report Block. Do you have a better theory to explain them? Somehow I doubt it. Da Schneib. Well, this is a bit over the top. Even with charm, strange, and bottom quarks all showing asymmetry, it's not enough. But it certainly is another step closer to being enough.
So this is a moderately big deal. The findings of asymmetry in the strange and bottom quarks both led to Nobel Prizes in Physics, so it's moderately likely this will too. Keep an eye on top quark experiments. If this is a property of all the heavy quarks, there could be some interesting physics involved. Keep an eye on the neutrino sector, too; asymmetry in that sector could add up to enough, with this new discovery, perhaps to close the loop and show the reason for the matter-antimatter asymmetry of the universe.
Which would be a big deal, no question. To be continued. The facts change. That is why the beliefs change.
Quarks and antiquarks are the only fundamental particles that interact through The findings may also indicate new physics beyond the Standard Model, which. Piasetzky; Meytal Duer, also of TAU's School of Physics; and Prof. The researchers discovered that the speed of a quark depends on the number of The team's new explanation can help to illuminate subtle yet important.
I understand that people want to see scientific statements as stationary, but they are not. That is why science is so powerful. But scientists, on the other hand, like static knowledge, and they like confirmations of the things that they say. One version contained a charmed quark and an antimatter version of an up quark, called the anti-up quark. The other version had an anti-charm quark and an up quark. Using LHC data, they identified both versions of the particle, well into the tens of millions, and counted the number of times each particle decayed into new byproducts. Adds Polyakov, "Particles might look the same on the outside, but they behave differently on the inside.
That is the puzzle of antimatter.
