In this paper, we present a detailed Monte Carlo simulation study of the triple-Higgs production through gluon fusion at a TeV hadron collider and explore the feasibility of observing this production mode.
Our study shows that, in order to observe the Standard Model triple-Higgs signal, the integrated luminosity of a TeV hadron collider should be greater than 1. We also examine how new physics can change the production rate of triple-Higgs events. For example, in the singlet extension of the Standard Model, we find that the triple-Higgs production rate can be increased by a factor of O Works referenced in this record:.

What is the criterion for a strong first order electroweak phase transition in singlet models?Here, we present benchmark scenarios for searches for an additional Higgs state in the real Higgs singlet extension of the Standard Model in Run 2 of the LHC.
The scenarios are selected such that they ful ll all relevant current theoretical and experimental constraints, but can potentially be discovered at the current LHC run.
We take into account the results presented in earlier work and update the experimental constraints from relevant LHC Higgs searches and signal rate measurements. The benchmark scenarios are given separately for the low mass and high mass region, i. Works referenced in this record:. GOV collections:.

Similar Records.A newfound particle discovered at the world's largest atom smasher last year is, indeed, a Higgs boson, the particle thought to explain how other particles get their mass, scientists reported today March 14 at the annual Rencontres de Moriond conference in Italy.
Physicists announced on July 4,that, with more than 99 percent certainty, they had found a new elementary particle weighing about times the mass of the proton that was likely the long-sought Higgs boson. The Higgs is sometimes referred to as the "God particle," to the chagrin of many scientistswho prefer its official name. But the two experiments, CMS and ATLAS, hadn't collected enough data to say the particle was, for sure, the Higgs boson, the last undiscovered piece of the puzzle predicted by the Standard Modelthe reigning theory of particle physics.
Now, after collecting two and a half times more data inside the Large Hadron Collider LHC — where protons zip at near light-speed around the mile-long 27 kilometer underground ring beneath Switzerland and France — physicists say the particle is a Higgs. Dave Charlton, ATLAS spokesperson agreed, the new results "point to the new particle having the spin-parity of a Higgs boson as in the Standard Model," referring to a quantum property of elementary particles.
To confirm the particle as a Higgs boson, physicists needed to collect tons of data that would reveal its quantum properties as well as how it interacted with other particles. For instance, a Higgs particle should have no spin and its parity, or the measure of how its mirror image behaves, should be positive, both of which were supported by data from the ATLAS and CMS experiments.
Even so, the scientists are not sure whether this Higgs boson is the one predicted by the Standard Model or perhaps the lightest of several bosons predicted to exist by other theories.
Seeing how this particle decays into other particles could let physicists know whether this Higgs is the "plain vanilla" Standard Model Higgs.
Confirmed! Newfound Particle Is a Higgs Boson
Detecting a Higgs boson is rare, with just one observed for every 1 trillion proton-proton collisions. As such, the LHC physicists say they need much more data to understand all of the ways in which the Higgs decays.
From what is known about the particle now, physicists have said the Higgs boson may spell the universe's doom in the very far future. That's because the mass of the Higgs boson is a critical part of a calculation that portends the future of space and time. Its mass of times the mass of the proton is just about what would be needed to create a fundamentally unstable universe that would lead to a cataclysm billions of years from now.

Proton-proton collisions at the Large Hadron Collider show events consistent with the Higgs boson particle.In this note we propose an overview on the current theoretical and experimental limits on a Higgs singlet extension of the Standard Model. We assume that the Boson which has recently been measured by the LHC experiments is the lightest Higgs boson of such model, while for the second Higgs Boson we consider a mass range of GeV to 1 TeV, i.
In this light, we study the impact of perturbative unitarity limits, Renormalisation Group Equations analysis and experimental constraints Electro-Weak Precision Tests, measurements of the light Higgs coupling at the Large Hadron Collider. We show that, in the case of no additional hidden sector contributions, the largest constraints for higher Higgs masses stem from the assumption of perturbativity as well as vacuum stability for scales on the order of the SM metastability scale, and that the allowed mixing range is severely restricted.
We discuss implications for current LHC searches in the singlet extension, especially the expected suppression factors for SM-like decays of the heavy Higgs.
We present these results in terms of a global scaling factor as well as the total width of the new scalar.

We ended the month with a total profit of 126 points which means we are now back in the game with an overall profit of 28. We're back with another update to our Golf Betting Expert review and we've seen a slight increase in the strike rate this month, however it still ended with a loss in the end.
We lost 19 points in total which gives us an overall loss of 97. Since last month we noticed that the advised starting bank on the sales page has now been upped from 200 to 500 points, which seems a much more sensible size after witnessing the massive swing in variance the service has experienced over the last couple of months.
We are going to continue following the service for another three months and will report back soon with our next update. It's been a turbulent time in our Golf Betting Expert review with a terrible losing run where just 2 out of 42 bets returned a profit.
After the bets from the Tour Championship and Portugal Masters had been settled, our 200 point bank had dwindled all the way down to 19. The next set of tips were received on the following Thursday ahead of the British Masters, but at this stage our bank was 0. Technically this is a bust bank, but we went on to record the available odds and waited to see what happened next anyway.
Since starting the review we are still down by 78. Clearly the advised starting bank of 200 points is not sufficient and we can't deny that we have lost confidence in the service. Despite this, we have decided to continue following the tips for a little while longer to see whether a recovery can be made and whether the recommended bank will be adjusted.
It's been a pretty awful start to our Golf Betting Expert review with a poor strike rate of 4. Just 3 bets from the 63 we received returned a profit which gives us an overall loss of 95. We did expect long losing runs as that goes hand in hand with golf betting, but we weren't expecting it to be this bad.
Hopefully we will see an improvement over the next month, otherwise this could turn out to be a disaster. We have also had trouble obtaining the advised odds for quite a lot of the selections, with our average odds being 57. This could be an issue as it will affect our bottom line in the long run.
These are unavoidable when betting at high odds and we can see from the past results that strings of 15-20 losing bets or more are not uncommon.Antique bulldozer
Selections are emailed out once per week on a Tuesday at around 11. Stakes are advised for each selection between 0. We will start with a three month review initially, but due to the nature of the service it's more than likely that this will run on for a longer period.
