After further review of the data from July’s particle discovery at the Large Hadron Collider, the new results point to the new particle having the spin-parity of a Higgs boson as in the Standard Model.

Geneva, 14 March 2013. At the Moriond Conference today, the ATLAS and CMS collaborations at CERN’s Large Hadron Collider (LHC) presented preliminary new results that further elucidate the particle discovered last year.  Having analyzed two and a half times more data than was available for the discovery announcement in July, they find that the new particle is looking more and more like a Higgs boson, the particle linked to the mechanism that gives mass to elementary particles. It remains an open question, however, whether this is the Higgs boson of the Standard Model of particle physics, or possibly the lightest of several bosons predicted in some theories that go beyond the Standard Model. Finding the answer to this question will take time.

Whether or not it is a Higgs boson is demonstrated by how it interacts with other particles, and its quantum properties. For example, a Higgs boson is postulated to have no spin, and in the Standard Model its parity – a measure of how its mirror image behaves – should be positive. CMS and ATLAS have compared a number of options for the spin-parity of this particle, and these all prefer no spin and positive parity. This, coupled with the measured interactions of the new particle with other particles, strongly indicates that it is a Higgs boson.

The preliminary results with the full 2012 data set are magnificent and to me it is clear that we are dealing with a Higgs boson though we still have a long way to go to know what kind of Higgs boson it is.” said CMS spokesperson Joe Incandela.

“The beautiful new results represent a huge effort by many dedicated people. They point to the new particle having the spin-parity of a Higgs boson as in the Standard Model. We are now well started on the measurement program in the Higgs sector,” said ATLAS spokesperson Dave Charlton.

To determine if this is the Standard Model Higgs boson, the collaborations have, for example, to measure precisely the rate at which the boson decays into other particles and compare the results to the predictions. The detection of the boson is a very rare event – it takes around 1 trillion (1012) proton-proton collisions for each observed event. To characterize all of the decay modes will require much more data from the LHC.

    You guys need to sell t-shirts with some of your SciTech pictures. Some of these pictures look like they would make cool shirts!

  3. “the particle linked to the mechanism that gives mass to elementary particles”

    Sounds like pre-school logic to me.

    Mass is not created that way. Mass is created by the inward expansion of time.
    Time is all that exists, and its sole property is self-expansion. There are not 4 or more dimensions, there is just Time – Time is the sole thing that exists.

    The universe actually grows from the outside in in an unbounded sense. Everything pushes in as result (aka gravity). Time also grows from the inside out, however this is bounded by the most recent time. The difference between the two creates the required fundamental differentiation that allows causality.

    With E-MC2, it is not so much “space-time” but Time creating space via overlapping. Time overlaps when the outward expansion of the past becomes greater than the power of the inwards expansion of more recent time (eg as exists in an observable sense in empty space – hence galaxies drawing apart), which fractures and divides singular plane Time, into spatially spherical units. What makes this work is that “past” time never dies, it is still expanding – but it is always within what expands from it.

    I am not a physicist, but I seriously doubt in the alleged properties of the Higgs boson. You might as well call it Santa Claus boson. It could not have anything to do with creation of mass.

    Higgs Boson has already got a relative in W+, W- and Z Bosons of the weak field .If the mass of three Bosons are added up (W+ or W- = 80.4 Gev and Z boson = 91.1 Gev) like 80.4+80.4+91.1= 251.9) which equals the theoretically predicted 2 Higgs Bosons of mass 125/126 Gev approximately. So in hierarchy Higgs Boson begets these W+, W- and Z Bosons which are bound in the nucleus as a ghost particle already accounting for its mass to produce electrons and electron neutrino which are pure particles. These electrons generated are not atom bound but newly generated in the conversion of proton to neutron. Here invisible gives rise to visible particles. This is well documented. Even the ordinary light photons are ghosts and these bosons overlap each other in LASER. Even the gravitons are ghosts. Hence you cannot altogether rubbish Higgs Boson. By the by all these bosons already discovered and yet to be discovered are just ghosts (because they can overlap one upon each other in the same space unlike real particle which occupies a definite volume in three dimensional space. So, we call them as concrete objects just like you and me and the material world we see all over. But we accept E=mc2 equation where energy and mass are inter-changeable. We see the electron – positron pair production in very high energy gamma rays (again ghosts) in the cosmic ray showers. Then we see that materialization of energy is possible. Annihilation , of course we are familiar in atom bombs and mass defect of atoms. Gluons which hold the up and down quarks in the neutrons and protons are nothing but ghosts whose effective mass far exceeds that of the material proton mass or neutron mass we see. The balance of mass is hidden as ghost gluon energy. Even in case of electron the so called particle is embedded in a ghost of electron field. and it is no point source. Thus we see in the nature that ghosts and particles are intertwined in a drama to present a material world. Of course these ghosts (bosons) are 96% of the cosmic energy which appeared during Big Bang event, and much of the ghosts are there in the Universe as 96% of Dark Matter and Dark Energy. They are scientifically true and cannot be dispensed. A detailed article can be read, written by me in “Science Frontiers- A Probe by Madan” which can be accessed in internet by the same caption or typing ‘vcmadan2’. If you agree that Energy can neither be created nor destroyed , then the logic is simple. Big Bang has released 10^19 Gev energy, whereas our CERN experiments dashed a proton against another proton to get hardly 1 Gev of energy. Here itself we get a plethora of secondary particles and mesons which are all unstable and sifting the data they came to know one such 126 Gev decay was there. The CERN energy produced all the known First, Second and Third generations of matter like quarks, mesons, Top, Bottom, Strange , Charm and electrons and electron neutrinos. They are all known to us. We strive to pick up the missing link 125/126Gev Boson particle from the debris. If you climb up the ladder, the hierarchy of such bosons would be much higher but all are unstable. We can never imagine to produce such a big energy to produce God Particle showers. Only those bosons which are embedded to a charge field or color field are localized and studied by us as W+, W-, Gluons (Red, Blue and Green and their anti). In color field the charge is trisected and called Red, Blue and Green). Even the electric charge is trisected like 1/3e in up, down and mesons quarks. The discovery of Higgs Boson will only be a one step up the ladder and higher energies cannot be found by mankind. If you want to discard the theory altogether lot of adjustments have got to be done in the Standard Model which is even more difficult.Thank You.
