Mike Smith Cosmos Posted August 19, 2013 Author Share Posted August 19, 2013 (edited) Quote The data are compatible with the Standard Model JP = 0+ quantum numbers for the Higgs boson, whereas all alternative hypotheses studied in this letter, namely some specific JP = 0-; 1+; 1-; 2+ models, are excluded at confidence levels above 97.8%. They looked at many different models (with different spins and parities) and worked out what the chances were that the data could fit the predictions of those models - it was very low. BTW the 0 is the spin the plus/minus is the parity - see here Quote This exclusion holds independently of the assumptions on the coupling strengths to the Standard Model particles and in the case of the JP = 2+ model, of the relative fractions of gluon-fusion and quark-antiquark production of the spin-2 particle. Stating how the experiment avoids one or twp pitfalls Quote The data thus provide evidence for the spin-0 nature of the Higgs boson, with positive parity being strongly preferred. The particle that they were testing was highly likely to be spin 0; it is further shown elsewhere that the particle is likely to be the Higgs Just One or two more Steps back on these 3 . If that is O.K. Please. [Like magnification back to ( x 5 to x 20) rather than x 150 ] mike Edited August 19, 2013 by Mike Smith Cosmos Link to comment Share on other sites More sharing options...
imatfaal Posted August 19, 2013 Share Posted August 19, 2013 They tested the higgs in three ways (the decay pathways). In each of these they looked at the results with various hypotheses in mind - it is highly unlikely that anything other than 0+ could give the data observed. More data and work is required for the highest levels of certainty - but higgs is highly likely to be spin 0+ as predicted. Link to comment Share on other sites More sharing options...

So are you saying that any particle with some particular spin , interacting with the Higgs mechanism via a higgs boson is not going to change its spin in any way by this interaction, or only if it is of a particular type of spin ? Fermions electrons, protons , neutrons ( half integer spins -1/2 1/2 3/2 ... ) firm ,heavy particles Bosons Higgs , Photon , Graviton ( whole integer spins 0,1,,2 .........) soft, light , force carrying things So the Higgs mechanism is remaining neutral as regards spin with spin 0 , wheras others of a certain type say on light photons , ( 1) ( so they do not acquire mass) And not neutral with say an electron or a proton , ( with half integer spins say spin 1/2 where the interaction with the Higgs would make them acquire mass to some degree or other . Is this by the Spin interaction . ? Is that right ? Is therefore the spin the vehicle for acquiring mass ? or am I going off on a tangent ? probably ! mike Edited August 19, 2013 by Mike Smith Cosmos Link to comment Share on other sites More sharing options...

Has there been any development, as to whether the Higgs boson in some way transmits the SPIN QUALITY to particles ( like all particles) that it interacts with to give the particles MASS ? http://www.scienceforums.net/uploads/monthly_08_2013/post-33514-0-93982200-1376952701.jpg .
