The Higgs should produce two bottom quarks. They have not been found but are extremely difficult to spot:-http://www.symmetrymagazine.org/article/the-higgs-shaped-elephant-in-the-room-"But the particles that led to the Higgs discovery were actually some of the boson's less common progeny. After recording several million collisions, scientists identified a handful of Z bosons and photons with a Higgs-like origin. The Standard Model of particle physics predicts that Higgs bosons produce those particles 2.5 and 0.2 percent of the time. Physicists later identified Higgs bosons decaying into W bosons, which happens about 21 percent of the time.-"According to the Standard Model, the most common decay of the Higgs boson should be a transformation into a pair of bottom quarks. This should happen about 60 percent of the time.-"The strange thing is, scientists have yet to discover it happening (though they have seen evidence).-"According to Harvard researcher John Huth, a member of the ATLAS experiment, seeing the Higgs turning into bottom quarks is priority No. 1 for Higgs boson research.-“'It would behoove us to find the Higgs decaying to bottom quarks because this is the largest interaction,” Huth says, “and it darn well better be there.”-"If the Higgs to bottom quarks decay were not there, scientists would be left completely dumbfounded.-***-"To be fair, the decay of a Higgs to two bottom quarks is difficult to spot.-"When a dying Higgs boson produces twin Z or W bosons, they each decay into a pair of muons or electrons. These particles leave crystal clear signals in the detectors, making it easy for scientists to spot them and track their lineage. And because photons are essentially immortal beams of light, scientists can immediately spot them and record their trajectory and energy with electromagnetic detectors.-"But when a Higgs births a pair of bottom quarks, they impulsively marry other quarks, generating huge unstable families which bourgeon, break and reform. This chaotic cascade leaves a messy ancestry.-***-"Bottom quarks produce jets of particles with all kinds and colors and flavors,” Mallik says. “There are fat jets, narrow gets, distinct jets and overlapping jets. Just to find the original bottom quarks, we need to look at all of the jet's characteristics. This is a complex problem with a lot of people working on it.”-"This year the LHC will produce five times more data than it did last year and will generate Higgs bosons 25 percent faster. Scientists expect that by August they will be able to identify this prominent decay of the Higgs and find out what it can tell them about the properties of this unique particle."-Comment: dhw and I spend mucho time debating the complexities of evolution which defy logic. Note here the complexities of the zoo of the underlying particles of our reality. I could ask dhw the same question he always poses about God's possible actions and motives in living evolution as too complex, too cumbersome, and therefore not reasonable. dhw, how reasonable do you find the particle zoo complexity which is well known, well described, and will probably find the missing bottom quarks? We have described these arrangements perfectly, but no one can give a reason for this arrangement. As in evolution we have no explanation as to why God did it this way. We must just accept it.
