Post-Higgs LHC Update

Just because the Higgs has been discovered does not mean there is any rest the the physcists at the LHC. They are now a few days out of the technical stop and have already returned to running with maximum bunch numbers (at slightly reduced intensity for now) and have added 0.33/fb, and they have done some special runs for TOTEM.

The CERN directorate would not feel that they are doing their job if they did not change the plan at least three times a year, so at the 4th July press conference the DG announced that they had decided to run the LHC for an extra three months and then shut down the collider for a longer period of two years. It will not restart at higher energy until 2015. There will be about 2 months extra proton physics this year which could add another 5/fb to 10/fb to the total delivered. The hope is that it will give enough data to study the properties of the Higgs and perhaps find something else so that the physicists have plenty of analysis to work on during the two year break while the LHC and the detectors are being upgraded. For more details see the ICHEP talk here

    It is not the Higgs Boson. It is a close cousin, which should make people very happy, as it is close enough to the SM to not invalidate prior physics, but it will mandate a huge amount of NEW modeling work to get to its phenomenology.

    Does anyone know when the most likely time for the next analysis/update will be? Are there any big meetings in September or October?

    • Philip Gibbs says:

      Difficult to be sure but I think they will want to run to the next technical stop in mid-september which might be enough to give them another 10/fb to double the data again. So far all major updates have roughly doubled the amount of data available. That does not take them to a convenient conference but they can always update at a special CERN meeting again. Big meetings are Physics in Collision (Sep) which may be too soon and Hadron Collider Physics (Nov) which may be too late.

    apparently important occasion but there certain facts in reality that has not been exposed in Physics. First the dark matter / energy syndrome must have a logical base by any stretch of imagination. Mass is the underpinning for those as yet unconfirmed observations, Long before the boson or gluon was even thought of the fundamental mass component forming space was identified in Vedic theory 10000 years back and its value identified axiomatically is 1.3 E minus 51 kg Moolaprakriti or MY . The Plancks constant is just MY x C^2 0r 9E+16 times. Not an accident. Hence in that spectrum of MY C^2 interactions trillions of bosons, gluons, gravitons , you name it and can be
    found by sledgehammering. Physics has indeed the daunting task of Picking MY value from a space that has a critica matter density FROM which gravitation starts as the ubiquitous acceleration. The Higgs boson is indeed the titanic component compared to the MY. The logic of MY fulfills the need for something that eliminates the puerile assumption and hypothesis that space can be vacuous or empty etc. The MY C^2 spectrum is the foundation for all the hidden happenings syndrome in Physics. It is the Neutrino spectrum as yet undetected, The Plancks constant is seven times the neutrino mass of 9.5 E minus 35 kg. If Planck constant as quanta or Photon can travel at light velocity then surely 1/7th that as a single neutrino MUST travel faster if momentum conservation has any meaning at all. All for so called “truth” while the real one in accurate 15 digit numbers lay hidden in another language. Perhaps most would rail at this write up but before you do that see http://sankhyakarika.webstarts… index.html for the logic , derivation and proof and see Sankhya Slide in PPT format giving aan overview graphically .

      What will be very interesting to me in a data analysis is how CLOSE the Boson so discovered got to the Higgs prediction. The greater life time is simply NOT going to go away as an issue.

      I expect that the renormalization calculations will be the first step as to bridge what is known as to Standard Model theory , and then to the actual experimental data. It will be particularly revealing to me what is delineated as a MUST fill in bridge

      I am betting on a special CERN meeting. And why is November too late ? This analysis will go on FOR YEARS especially if new physics is mandated by the findings.

      Why are you in such a hurry to solve this ” immediately” Dr. Gibbs? I predict this will take YEARS to resolve.

      Proper bridging of the difference between SM physics, and this new finding I predict will lead directly to a solution to the DM-DE mystery.

  4. The discovery of a new subatomic particle that is likely the elusive Higgs boson — a particle thought to give all other matter its mass — could be an important step toward uncovering the invisible stuff that makes up the majority of the universe, physicists say. A new path of scientific inquiry into the mass-generating mechanism that was never before possible. The Higg’s boson role is to give the particles that make up atoms their mass. Without this mass, they would zip around the cosmos, unable to bind together to form the atoms that make stars and planets – and people. This opens up the possibility of there being more than one Higg’s boson and could lead to a new understanding of dark matter, the mysterious substance thought to make up a quarter of the universe. A condition at which the linear polarization becomes a circular polarization. As particles passed through it, they picked up mass, giving them size and shape and allowing them to form the atoms that make up you, everything around you and everything in the universe. an invisible energy field called the Higgs field formed.
    .We want to know whether it behaves like a mass-giving Higgs, and more specifically whether it behaves like the Higgs predicted in the standard model. One important task will be to carefully measure the different ways that the particle is produced and decays inside the LHC detectors. The rates could be altered by the existence of exotic new particles not predicted by the standard model that would interfere with the underlying quantum mechanical behaviour. With the help of invisible cloaking screen of John Pendry for a possible way of stopping the resonance from linearity to circular polarization.

    The utter lack of logic beats me. Light was supposed to travel on the ether as medium, but because Morley failed, the ether was summarily removed. It meant that Light traveled on NOTHING and Maxwell scribbles justified that by saying it is by itself and through itself. Descending to this level , without a sound logical derivation, really reduces Physics to the bookshel of Myths, Fairystories and Grandma tales.Now have realised that NOTHING indeed has all this blessed DARK stuff which could not be justified by the SM, QED, String, Susy and in fact by any theory so far. Isnt that a blind alley that Physics had got into because of replacing Ether with Nothing?
    Now the pundits have sneakily tried to turn the table around big recalling a forgotten residue from SM. calling it Higgs etc. Now the question every human being will have to answer, not only scientists of any and every breed, Where from did the higgs turn up from the ocean of nothingness Physics had been reduced to depending on?Can any thing, be it boson, gluon, graviton etc can ever turn up from sheer NOTHING? The answer is simply, strictly, logically,is a resounding NO. Since the ivory tower replaced the ether with nothing out of which geodesics sprouted magically and yet could not complete neither Quantum, SM or GR/SR should they not restructer that nOTHGING INTO SOMETHING that plain common sense can buy? For your information is has been done in a theory called Sankhya based on axioms that defines that something in relative terms as the Moolprakriti in Sanskrit or the elemental dynamic state as 1.3 E minus 51 kg and maximises in a strictly logical mode to the maximum called PURUSHA at .9149 kg. The entire manifest spectrum phenomena as Quarks, hadrons, leptons, neutrinos, photons with their subordinate groups of ferrnions, bosons and all that can be discovered in the future. Will any Physicsts have the humility JUST SEE IT FOR A SECOND for it tkaes all the hard work of discovering something from notheing forever. http://sankhyakarika.webstarts.com / index.html. I assure you will be surprised

    It makes sense to add some more time running at optimal settings, to increase the ratio of physics production vs. the technical stops (+recovery) and machine development.
    Winter also has fewer thunderstorms which like to disrupt the electricity, but a cold wave could be a problem…

    Any idea as to how they’re getting on with improving beam stability and losses? Why are the losses on beam 2 greater than on beam 1?

    • Philip Gibbs says:

      Something apparently changed at the technical stop. I dont know if they really understand it or not. For now they seem to be continuing with luminosity reduced by 10% but they are still knocking out 1/fb per week so maybe they will just live with it until the next stop.

      • carla says:

        Before TS2, there were losses during ramp-up and squeeze and so were spread over a far greater length of time, whereas now they seem to occur within a smaller time window during adjust and at the start of collisions.

        It’s all very interesting :)

    Bad engineering. And no I am not kidding

    If it were just bad engineering, that would be one thing. It is also that the firm ware still has bugs.
