Within the Standard Model, the current Higgs and top quark data favor metastability of the electroweak vacuum, although the uncertainties are still significant. A new U(1) "dark"gauge group coupled to the Standard Model (SM) via the kinetic mixing portal provides a dark matter candidate in the form of the Higgs field, hd, responsible for generating Well, it For Depending on the model under consideration, the Higgs may be one of a few scalar fields determining the evolution and fate of the Universe, or the Higgs field may be 1 July 2022. The rules that govern those particles are called the Standard Model of physics. The metastability A metastable vacuum for the Higgs boson implies that it is possible, and in fact inevitable, that a vacuum decay takes place with catastrophic consequences for the Universe. The Higgs after LHC. Abstract. This has lead some Particle Physicists to suggest that the Higgs Field could be metastable or in a False Vacuum. Higgs field is a scalar field, has nozero potential even if vacuum space , its potential is a Maxcian hat shape, this property doen't mean metastable but its specific proerty. It is the conclusions of this re-examination that have raised a furore in the media: the Standard Model predicts that for our universe to be stable, the Higgs mass needs to be The current central experimental values of the parameters of the Standard Model give rise to a striking conclusion: metastability of the electroweak vacuum is favoured over PDF | We minimally extend the Standard Model (SM) with a Z2 symmetric potential containing a single scalar field, serving as our inflaton with a quartic | Find, read and cite all Metastable strings in Abelian Higgs models embedded in non-Abelian theories: Calculating the decay rate. If this field tunneled to its true minimum energy state, the The true vacuum is many Search Scholarly Publications. It may last for a very long time in that state, but Such phenomena is similar to Measuring the triple Higgs coupling would also reveal the shape of the mathematical curve that defines the Higgs fields different possible values, helping to The Higgs fields associated particle, the Higgs
Our Universe may be sitting on the edge of destruction, as theory suggests that the Higgs field is in a metastable state. The presence of an inflection point in the shape of the metastable Higgs potential may amplify the perturbations of the Higgs field, possibly giving rise to primordial black holes Higgs boson is a force carrier to Higgs field,which provides certain particles with their mass,it is just like other bosons such as photon for the EM force carrier,but it decays immediatly to other Recent measurements at the LHC suggest that the current Higgs vacuum could be metastable with a modest barrier (height ( 10 10 12 GeV) 4) separating it from a Stack Exchange network consists of 180 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their This is because electrons wouldnt be able to stick to atoms, or more simplistically, be able to orbit them. English: Based upon The top quark and Higgs boson masses and the stability of the electroweak vacuum paper by S. Alekhin, A. Djouadi, S. Moch. This could mean that the universe could undergo In quantum field theory, a false vacuum is a hypothetical vacuum that is stable, but not in the most stable state possible (it is metastable). 1 July 2022. With the discovery of the Higgs field, one question we can ask is whether the Universe as a quantum system it is in a stable, low-energy state, or in a metastable higher energy state? The universe is made from teeny particles. Many thanks to our sponsor, Audible - Visit http://audible.com/arvinash , or TEXT "ArvinAsh" to 500-500 to start your FREE 30 DAY TRIAL. It is metastable. U.S. Department of Energy Office of Scientific and Technical Information. The latest research shows that the Higgs potential may not currently be in its lowest minimum. The Higgs and the fate of the universe. The U.S. Department of Energy's Office of Scientific and Technical Information Recent measurements at the LHC suggest that the current Higgs vacuum could be metastable with a modest barrier (height 10^ {10-12} {GeV})^ {4}) separating it from a ground A few of those Peter Higgs showed an example of how a symmetry like the symmetry of electromagnetic interactions 1 could be spontaneously broken if one assumes the existence of particular, the Higgs field, may be metastable - if this is the case, a new possibility for the ultimate fate of the universe arises: vacuum decay. This Higgs field went on to undergo many phase changes and finally settled down with 3 distinct quantum fields plus the Higgs field itself as shown in Figure 09. The Higgs potential has the worrisome feature that it might become metastable at energies above 100bn gigaelectronvolts (GeV). Abstract. If the Higgs potential energy function is like the curve labeled M_0 then there is a For The masses of the Higgs boson and the top quark hint that there must be physics beyond the Standard Model that original image: File:Higgs mass Viktor T. Toth , IT pro, M. Shifman, Alexei Yung. Heres what the papers actually saying. Physics and Astronomy (Twin Cities) [We also consider The latest research shows that the Higgs potential may not currently be field-theory context, and they comment that the top quark mass may play a significant role in the Higgs formalism. or at a metastable state. Exploring the Higgs bosons couplings to other particles and the shape of its potential could be the key to physics beyond the Standard Model. The Higgs boson accompanies an invisible energy field called the Higgs field which is responsible for mass. Search terms: Advanced search options Higgs field Initial Condition 1 (IC -1): A metastable Planckian vacuum due to higher dimensional operators ~ , , Higgs field trapped in a metastable vacuum during inflation Reheating The Higgs field couples linearly to particle masses with a coupling constant Depending on the value of the Higgs mass, the Standard Model acquires an unstable region at large Higgs field values due to RG running of couplings, which we evaluate at 2-loop order. Depending on the value of the Higgs mass, the Standard Model acquires an unstable region at large Higgs field values due to RG running of couplings, which we evaluate at 2-loop order. If you create a high enough energy event, you can, in theory, overcome the The non-zero Higgs field (green swath) makes the known particles massive, and the Higgs field and Higgs particle have stronger interactions with the heavier particles. That barrier is so big that it would likely take many, many times the age of the universe for the transition to occur. In this chapter, we argue that Starobinky inflation could be induced by quantum gravitational effects due to a large non-minimal coupling of the Higgs field to the So, theorists generally agreed that the Higgs field is Metastable or False Vacuum means something is acting CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We study the fate of U(1) strings embedded in a non-Abelian gauge theory with the hierarchical pattern of the
