Matter - Antimatter Asymmetry

02/02/2017 2:22 PM

Interesting read....

The LHCb experiment has found hints of what could be a new piece of the jigsaw puzzle of the missing antimatter in our universe. They have found tantalizing evidence of a phenomenon dubbed charge-parity (CP) violation in particles known as baryons – a family of particles whose best-known members are the protons and neutrons that make up all the matter in the universe

The Standard Model (SM) of particle physics predicts that a tiny amount of CP violation exists also in the baryon sector. Although CP-violating processes have been studied for over 50 years, no significant effects had been seen with baryonic particles. Moreover, CP violation as described in the SM is not large enough to account for the much larger matter-antimatter unbalance. Therefore, other CP violation sources must contribute, and one of the main goals of LHCb is precisely to search for new sources of CP violation.

Is that supposed to be a complete sentence in the world of logic?

"... best-known members are the protons and neutrons that make up all the matter in the universe ..."

All? Shame on phys.org. These two nucleons account for much of the matter in the universe but certainly not all of it. Other baryons include Lambda (mentioned in the article), Sigma, Xi, and Omega. Non-baryonic matter includes electrons, muons, and tau particles, and their associated neutrinos.

That's a good point.

All of that aside, how do we apply it?

Well, it cannot be applied like peanut butter onto toast.

In other words, it has no obvious application. Scientia gratia scientia

You can't. Unless you wan't to count paying taxes.

It sounds like they (they being the thousand of particle physicists) are smashing a couple of protons into each other. That requires a special kind of tool that you can't buy online.

So when they smash two protons together you'ld expect the same result each time right? It's like cracking a couple of eggs and having breakfast.

These guys are so surprised that they get up to 20% "shell in their eggs" that they write a press release and call it a discovery. But wait what?

I'm sure there's more to it than that of course, but I'd rather have 2 eggs than keep paying for the next new "super collider"

Re: Matter - Antimatter Asymmetry

The Large Hadron Collider is a project jointly funded by CERN member countries, with additional money for experiments coming from CERN and private research organisations. About half of CERN's funding comes from Germany, France, and the U.K., whilst CERN's other 17 member countries contribute the other half of the budget.

Now let's look at some costs: the cost finding the Higgs boson, for instance. BIG project. Took 14 years and cost an estimated $13.25 billion, paid for by all 20 CERN member countries. But had the U.S. footed that bill by itself, it still would have amounted to less than 2.2% of the U.S. military budget for 2013 alone.

If you're looking for someone to buy your breakfast, take it out of the DoD's hide. You can't eat bombs, mate.

The dod budget? Those words don't really go together. I have to avert my eyes when I see it.

I've nothing against the science.. just the cost.. and the product.

Now China wants to feel the pain of discovery and plans to plunk $6 billion plus on anew super collider twice the size of the LHR.

I don't care what country is paying for it. The citizens are paying for it with what in return?

How many colliders do we need? We were getting along fine before we had them.

What the optimal size of such a device? Why not build it?

Basic research has always had long-term payoffs. It drives our understanding of the universe; from that understanding the utility payoffs are incalculably high. These are new ideas and new innovations that later spawn new products, services, companies, industries and affect human capabilities further down the line.

Our fundamental understanding of electromagnetism has led directly to our ability to manipulate electrons in both the power grid and in microprocessors, in lasers, transistors and diodes and a host of other semiconductor devices. Every single one the product of somebody's conducting basic research.

Elementary particles and their interactions have given us electromagnetic power generation, microprocessors and everything in-between. Research and development in accelerator technology has produced a direct impact as that technology has been refined and distributed.

Today there are more than 17,000 particle accelerators in operation around the world; not just at research institutions like CERN, but also in private industry in hospitals and other locations.

Beyond the broader scale and scope of fundamental discoveries there is no shortage of dividends on the investments made: PET* scans, superconducting wire, cancer treatments, grid computing, the Internet and industrial material treatments are a tiny fraction of the payoffs we’ve seen so far.
Advances in medical technology and health care treatments; broader economy-wide competitiveness and efficiency gains, and intellectual capital are examples of yet other benefits. Just within materials science, whether it’s treating plastics and turning them into films, implanting ions into silicon chips, or developing the components of artificial heart valves, we would not have this core understanding without investments made generations ago in accelerator technology and research physics.

You can thank CERN for inventing the technology that made it possible for you to read this comment just now.

clap clap clap

Spoken like a paid spokesperson for the industry.

Well said..I'm not saying I agree 100 percent, but I'll look into it.

I'm just trying to protect local interest at our (now) puny fermilab

I just think there's a point when you have to many cooks in the kitchen.

what's next? 5G?

Other than following its developments for a number of decades, I have no connections with that 'industry' whatsoever, nor have I ever received one single cent in payment.

FermiLab, there in Batavia, is practically in your backyard. Maybe pay them a visit, take a tour and ask them your questions. You might learn a great deal that you didn't know before. You aren't afraid of learning new things I hope? Some people are, you know, because it makes them question their assumptions, pushes them out of their comfort zones and, worst of all, makes them think. You know the type. The ones who are left behind in the dust? Who don't know shit from shinola? Them.

Look into it. Visit FermiLab. You'll be pleasantly surprised.

I'll go this summer.. It's been back on my list, but I'll move it forward and let you know my thoughts. I've driven past it many times.

On a road trip I took the initiative to make the long out of the way drive up to the VLA in New Mexico and walked the grounds without hassle. I was also given permission to up into some rooms where they were working.

I went there for the science, energy, and architecture. All of it delivered 100 percent.

I expect the same with Fermi. A bike ride might be nice

of course I walked up those stairs!

Cool. I'd be interested in hearing your experiences.

I passed through Socorro in 2013 and wanted to see the telescope. It's not all that far from there (about 50 miles) but I was very short on time. :(

But bombs are tangible, palpable objects that can be delivered to an intended target and prosecute our enemies with complete extreme prejudice.
