When was Higgs Boson Found at LHC?
The Higgs boson first arose after a process called electroweak-symmetry breaking, which is a bit technical to explain in detail. Basically, the current theories for particle physics state that at a certain energy level (higher than we can reach at the moment) the electromagnetic force merges with the weak nuclear force. Below this energy level (or temperature) the two forces are distinct. You can view this as a phase transition, and the Higgs boson is a by product of it. This phase transition should have taken place mere seconds after the big bang, so if they exist (they haven't been experimentally verified), they have been present since almost the very start of the Universe.
Why the particle higgs boron has not been observed?
Three reasons: 1) Its large mass requires a LOT of kinetic energy in any collision to end up with enough energy to even possibly result in a Higgs Boson being created. That's why no particle accelerator prior to FermiLab or CERN had anywhere near enough energy to even hope to make a Higgs. 2) The Higgs is a VERY unstable particle -- once created, it breaks down into other particles in a time on the order of 10^-22 seconds. No device can possibly detect a particle in existence for that length of time, so we are left with looking for the decay products of a Higgs. 3) A LOT of other particles have decay products that very closely resemble that of the Higgs, so we can never be 100% certain that "these decay products are from Higgs Bosons, while these are not." All we can do is make a LOT of collisions, record the decay products of all of them, and then ask the question, "What is the probability that NONE of these decay products are a Higgs?" The most recent data from CERN have led scientists to state that the odds that zero Higgs were created is 1000 to 1 -- pretty good odds. However, particle science protocol requires that this probability must be reduced to a million to one before stating, "The particle that we were looking for was definitely created during these experiments." That announcement will probably occur in the next year or so.
How does the presence of the boson in nuclear decay breaks affect the overall process?
The presence of the boson in nuclear decay breaks can impact the overall process by influencing the stability and energy levels of the nucleus, potentially leading to different decay pathways and rates.
In beta decay what is emitted?
Beta- decay involves changing a neutron into a proton, with the emission of a W- boson, said boson then decaying into a electron and an electron antineutrino. Beta+ decay involves changing a proton into a neutron, with the contribution of energy, and then the emission of a positron and an electron neutrino.
What is the beta decay of radium?
226 Ra 88 ---> 225 Ac 89 +W boson W boson ---> e- + neutron
What is a Z boson?
The Z boson is an elementary particle that mediates the weak force, one of the fundamental forces of nature. It is electrically neutral and plays a crucial role in processes such as nuclear beta decay and neutrino interactions. The discovery of the Z boson in 1983 provided strong evidence for the unification of the weak electromagnetic forces.
What is the use of higgs boson?
One might separate the answer into two concepts, firstly, the function of the particle in forces affecting matter - or particle interactions; and secondly its notional role in our understanding of the universe as expressed in the Standard Model. On the former point, the Higgs plays a significant role in the weak interaction crucial to fission and famously responsible for beta decay; and in some particles' acquisition of mass. On the latter point, the Higgs plays a role which can be said to complete the widely-accepted Standard Model predicted long ago. Lack of direct non-theoretical evidence of its existence is considered a major gap in particle physics which already has abundant evidence for other particles that constitute the Model. This effect gains the particle significant attention because of the perceived importance of resolving a crucial incompleteness in the Model which would be addressed by the particle's experimental verification. This problem inspired decades of research and the construction of one of the world's most complicated and expensive particle colliders, the LHC. Higgs theory explains the reason behind why certain particles evidence mass where, based on rules governing their interactions, they should have no mass. Considerable excitement was generated when studies of candidates produced in LHC collision events in 2012 seemed to verify particular properties of the Higgs including its predicted parity, spin, and mass-energy.
What is a weak boson?
A boson responsible for carrying the weak nuclear force (responsible for beta decay). There are three different kinds W-, Z0, and W+ all rather heavy and acting only over short ranges.
How does the Higgs field affect quantum entanglement?
The Higgs Field has nothing to do with quantum entanglement. Quantum Entanglement is the phenomena that, when a particle decays into two particles, they travel in separate directions. When one particle is observed to be spinning in one direction, then we will immediately know that the other particle is spinning in the opposite direction. However, neither particle is spinning until it is observed, yet the other particle suddenly "decides" which way it is spinning as soon as the first is observed. Particles interacting with the Higgs Field (all of the particles that exist interact with the Higgs Field) simply take on mass, which depends on the strength of the interaction with the field. If a particle decays, then it will decay into a particle-antiparticle pair. Since all particles and their antiparticle counterparts have the same mass, there is no entanglement.
What were the forces in the god particle?
The God Particle, referred to by scientists as the Higgs Boson, is responsible for a particle having mass. Most particles in the universe have mass. However, if symmetry is to be preserved, all particles must be massless. This is a problematic result of the universe simply existing. In order to have symmetry preserved, there must be some field that is being interacted with. Higgs Particles (in order for the Higgs Mechanism to work there must be more than one) essentially generate a field. Heavier particles interact more with the field and lighter particles interact less. It can be thought of as wading through a pool: you have a harder time moving if you apply more force with your legs but it is easier to move if you use less force. The Higgs Particles are expected to have a spin of 2 and to be electrically neutral. They are not expected to interact with any forces except for gravity and the Weak Force (responsible for particle decay).
How could a neutron become a proto n?
A neutron consists of three quarks, a up quark and two down quarks. One of these down quarks can decay into an up quark (which is lighter) and a W- boson. You now have two up quarks and one down quark which makes up a proton! Your neutron has changed into a proton! The W- boson goes on to decay into (probably) an electron and anti-electron neutrino.
How does the W boson affect beta radiation?
The W boson is the carrier of the weak force (weak interaction), and the weak force is the "boss" of beta decay. The weak interaction mediates the changes that take place in an atomic nucleus just prior to the emission of a beta particle. Let's look at that. In beta decay, one of two things happens. One is that an up quark in a proton becomes a down quark, and the proton becomes a neutron. The weak interaction mediates this, and a W+ boson appears, then becomes a positron and a neutrino. In the other case, a down quark in a neutron becomes an up quark, and the neutron becomes a proton. The weak interaction mediates this, too, and a W- boson appears, and then becomes an electron and an antineutrino. You can use the links below to learn more.
