just wondering."Is it possible to take a tachyon formula with the results of matter and antimatter and fiqure out the fractionalisation in 3 dimensions?
-
@mathforphysics "Only integrals", yes. But many of them are complicated enough to fill the working life of many theoreticians. Most LHC studies use hadrons somewhere (if not in decays, it is still a p-p-collider...), so QCD is included if you look at the process in theory.
-
It's only integrals. QCD is more complicated, but it is essentially the same. A discussion of classical and then quantum scattering is reasonable. Then they could mention that QCD is more complicated and why.
-
@mathforphysics Up to a level that they could calculate cross-sections for e- e+ scattering on their own, for example? LO, NLO, NNLO, ...?
And I think we agree that e+ e- scattering is one of the easiest things with "real-life" applications. Throw in some QCD and you get the real mess.

@Jcapmusician1394
Some scientists have done some excellent physics, to discredit all conceivable LHC disaster scenarios. If you'd like to relieve yourself of any safety concerns, you can paste the following terms into Google:
cdsweb the lhc is safe
That will take you to an informative hour-long video (Record#1120625) which summarizes the The LHC Safety Assessment Group (LSAG) report.
The physics world really does include some knowledgeable people. Not many, but enough.

@RealityEyes01
Fortunately, the physics analyses in the LSAG report are available for any member of the public to view in a completely open, transparent way. A good start is to paste these terms into Google:
lsag web cern lsag-report.pdf
A key point:
Extremely high-energy particle collisions occur naturally everywhere on Earth (and the universe) every day, due to natural cosmic ray particles. The LHC isn't creating a "new" phenomenon, but rather reproducing a commonplace phenomenon for study.
