If the fifth force is a gauge force like the three in the Standard Model, then the symmetry of the Standard Model needs to be extended. would a linear e-p collider able to verify it? what is the most parsimonious extension of the SM that can accommodate it?ītw any idea how long it might take to verify a 17mev vector boson? should tevatron or lhc be able to verify or are hadron collisions too messy. What is your preferred explanation for 750 gev diphoton if it turns out to be a verified particle. In the same way buildings are still built using Newtonian physics instead of general relativity, the SM remains a really good approximation in many measurements, no matter what comes up beyond it.ĭepends on which of the 400 publications you prefer. It would mean we need an extension of the standard model. It is not certain, but expected, that first results are shown beginning of August. "May confirm" is an empty statement - getting larger datasets can always either confirm or not confirm things seen in smaller datasets. It is a fact that the 2016 dataset exceeds the 2015 one already (since yesterday). could these 2 new particles be a part of a hidden sector? i.e the SUSY-partner of a 750 GEV scalar boson is also a fermion. #Boson x crack plusLastly, if this x-boson and the earlier LHC 750 GeV diphoton excess boson are both validated, how does the 2 taken together effect the preceding physics? i.e a standard model plus both a 17mev vector boson and 750 gev "scalar" boson on higgs hiearchy, SUSY, dark matter. what would be its properties, mass, stability, dark matter candidacy and would the LHC be able to see its SUSY-partner? could this 17mev vector X boson be a SUSY partner of a known SM or SUSY particle?Ī SUSY partner of a 17 MeV vector gauge boson X would be a fermion. i.e does it alleviate or make worse things like FCNC. How does this effect higgs stability and higgs hierarchy? I.e Feng et al suggests it can explain the muon 3-sigma anomaly via virtual loop processes How does this affect the current SM, including virtual loop diagrams? Subjects: High Energy Physics - Phenomenology (hep-ph) High Energy Physics - Experiment (hep-ex) Nuclear Experiment (nucl-ex) Nuclear Theory (nucl-th)įor sake of discussion let us say that these results are valid, and there is indeed a new previously unknown 17mev vector X boson. The protophobic X boson may also alleviate the current 3.6σ discrepancy between the predicted and measured values of the muon's anomalous magnetic moment. The X boson mediates a fifth force with a characteristic range of 12 fm and has milli-charged couplings to up and down quarks and electrons, and a proton coupling that is suppressed relative to neutrons. The data are explained by a 17 MeV vector gauge boson X that is produced in the decay of an excited state to the ground state, 8Be∗→8BeX, and then decays through X→e+e−. Recently a 6.8σ anomaly has been reported in the opening angle and invariant mass distributions of e+e− pairs produced in 8Be nuclear transitions.
