In an interview with the scientist website, Prof. Gross says regarding the question of whether it is the Higgs (in the news) or just one of many Higgs bosons: "We physicists believe that nature is more complex than the standard model alone."
"It is now possible to drop the title "like" from the particle that until now we called it a 'Higgs-like particle' and be satisfied with the 'Higgs'," said Prof. Elam Gross from the Weizmann Institute, who in recent years has been coordinating the Higgs group at the Atlas particle accelerator facility in Sarn next to Z, in an interview with the Higgs website.

Prof. Gross is currently at a scientific conference dealing with the Higgs in Aspen, Colorado, where the new findings of the scientists of the two major experiments at Sarn: Atlas and CMS were presented. and which we reported for the first time yesterday following an announcement by the accelerator's management.
"Until now we have called the discovered particle a 'Higgs-like particle', and according to the results of the data analysis from the two experiments in which it was discovered, it can simply be called a Higgs particle. But not necessarily the Higgs particle. Beyond that, we also confirmed the existence of the Atlas particle with a significance level of 10 standard deviations, which is a huge number. There is no doubt that we have a new particle. The question is what is this particle? Each particle has an identity card consisting of its collection of properties and quantum numbers in which there are the more significant ones such as its mass which we know is close to 125 GeV or 125 times the mass of the proton. But there are other properties of a particle that allow us to label it: the Higgs is supposed to have zero spin and positive parity, and the characteristic quantum number of spin and parity is zero plus. It is clear to us that if we find evidence that the particle has zero plus, it will bring us closer to knowing that it is indeed the Higgs."
"Moreover. According to the standard model, the Higgs gives mass to all elementary particles (for example not to a proton consisting of three quarks but only to the elementary particles themselves). The strength with which it clings to the particles depends on their mass. This is another thing we wanted to measure - does its coupling to different particles such as the bosons match those expected from the standard model, so we also measured this and found first that there is evidence that strongly supports his claim that his spin and parity are zero plus. His couplings to the particles are indeed relative to the mass as we expected, and very close to those expected from the standard model. Therefore, in light of the evidence accumulated in the two experiments regarding the mass, spin and parity and its various couplings, CEO Rolf-Dieter Oyer, who was the first to announce in July: WE HAVE IT, found it appropriate to remove the word "like" from the name of the particle and now we see a particle Higgs, but still cannot say with certainty that it is still the same particle expected from the standard model."
"Not sure it's the only Higgs"
According to Prof. Gross, it is not certain that this is the end of the story: "We found a Higgs particle, not the Higgs particle (in the news). Although its properties are those expected as the Higgs particle should look like according to the standard model, only the future will tell if it is indeed the Higgs particle expected in the standard model or if, as the physicists very much hope, it is just one particle from a spectrum of Higgs particles, which belong to extended models that include the model the standard, and which allow us to answer more open questions in nature. We physicists do believe that nature is more complex than the standard model alone, and only the next few years, and many of them, will be able to definitively answer the question of whether our world is even more complex and beautiful than what is currently visible to the eye."
Is the LHC ready to give these answers?
Prof. Gross: "The LHC will give the answer in a few years. Now we're going to close it for an upgrade, raising the energy and the luminosity—the proton collision rate—just so we can look for things beyond the Standard Model and also better study the Higgs properties. At the conference in Aspen we came up with the idea of changing its name from HIGGS LIKE to STANDARD MODEL LIKE HIGGS. Is this the end of the story? - I hope not."

Happy holiday to everyone,
A few questions for those who understand:
According to the standard model, can the Higgs particle exist without coupling to another particle?
Since light is affected by gravitation, is a photon in Higgs coupling, and if so, how is it possible for a photon to travel at the speed of light, and its energy does not turn into mass?
Is it possible that the dark matter that astronomers hypothesize could be an exotic form of the Higgs particle, since it has a gravitational effect on matter?
One might think, "positive relationship"... let him say that after the divorce
typo: “luminosity”, not “minosity”
Thanks to Ehud, I understood the principle

There were indeed a number of interruptions in my answer, the forgiveness is with you. It should have been written
Excitation of the electromagnetic field is a photon. As you know we are
Dealing with the quantum theory and quintot (transformation into discrete quanta) of Sade
The quantum gives particles, but the field fluctuations and even its average value can
to cling to the particles and give them mass through the interaction. This is what
which makes the Higgs field. A quintet of the Higgs field gives the Higgs particle
And the mass for the elementary particles is given by the average value of the Higgs field
Thank you Ehud, but you used the term "ecstasy of a field" which is not clear to me. The example "ecstasy for Heda is a photon" is not clear to me either. Did you mean that it is only the effect of the Higgs that gives the mass and not its connection to other elementary particles? Anyway, thanks for trying to explain it to me.
good week

The Higgs is a quantum field, coupling to the field gives the other particles the mass
The Higgs particle itself is an ecstasy of the field which is short-lived and massive.
To illustrate, the electromagnetic field exerts a force on particles, ecstasy
L Heda is a photon (in this case massless).
Another thing that I think is missing here is the numbering of the responses, many times you want to refer to a certain response, and without numbering it is quite difficult.
Excellent, only this link should appear on the main page of the site and be available to everyone.
or! Thanks!

At least for now
Following on from YM's request, the "latest articles" link is indeed missing here, new articles appear at the top of the page for a short time only, then are dispersed to the various categories and it is very difficult to keep track of what is new and what is not, especially for those who enter here once every few days. In the previous format of the website, I could always go to the "latest articles" link and see all the latest articles in the order of their publication, even those that were published here a week, two weeks or two months ago.
I think that such a link should include a complete list of all articles (without exception) sorted by date, just as it was in the previous format (a partial list of the last 20 or 30 articles is not enough, it should be a complete list of everything published, sorted by date )
If the Higgs particle is the one that gives the mass to the elementary particles, how is it possible that its mass is 125 times that of the proton? After all, the elementary particles are smaller. Is this not the rest mass of the Higgs particle?
I would be happy to explain
Thanks

I forwarded your request to Rami.

Hello Mr. Blizovsky!
Is it possible to increase the number of articles in "Latest Articles"? You can keep the size of the SCROLLER the same size and put a longer history in it. It's enough that I haven't visited the site for a few days and I'm missing interesting articles, which is a shame
