Re: Magnetic monopoles found?
JNW, would you like to provide legitimate references? You do know we have detectors in space recording cosmic rays and ultra-high energy photons directly? Yes, I know about space detectors, and high altitude balloon detectors. These detectors don't have a very large collecting area. Cosmic rays of ...

Re: Magnetic monopoles found?
It takes a cosmic ray proton traveling at 10^17 eV and hitting a stationary proton to have the same CM energy as the LHC has with colliding protons. This makes no sense. The LHC's center-of-mass proton+proton collision energy is 1.4 x 10^13 eV. The 10^17 eV is from a CERN safety report: http://cern...

Re: Magnetic monopoles found?
The cosmic rays do exactly the same type of stuff what the LHC does. I'm not so sure. It takes a cosmic ray proton traveling at 10^17 eV and hitting a stationary proton to have the same CM energy as the LHC has with colliding protons. We know that many low energy cosmic rays are protons, but what d...

Re: What is the emergency shut off for the CERN LHC?
If something goes 'amiss' or terribly unforeseen how do they turn it off, The LHC will shut down automatically if any problem is detected. It can also be shut down manually, of course. you have 15 minutes to reach a safe distance warning, what is their strategy? Everyone is already a safe distance ...

Re: Happy Holidays!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
That's a great limerick, but I'm having a little trouble with the line:
"is not to make them flatter".
It seems smoother if I say:
"is not making them flatter".

Re: Magnetic monopoles found?
In the LSAG they say a light proton eating monopole will eat 10^18 before exiting the earth, but what happens after that? Only the ultra-heavy GUT monopoles can eat protons. The light monopoles that the LHC might produce never eat protons. The only problem monopoles might cause is if the LHC produc...

Re: Several biggest errors of particle physicists.
... magnetic hole can be created at the p-p collisions with 0.25 TeV per proton. ... Do you want to test these conclusions on LHC? Relax, the LHC will never reach 0.25 TeV per proton. It can only do from 0.45 TeV to 7.0 TeV per proton. 0.25 TeV is well outside that range. So we are safe! :happy-jum...

Re: Several biggest errors of particle physicists.
Created magnetic hole captures protons; destroy them onto positron and x-boson (or onto μ+ and x-boson, or onto pi+ and x-boson); ejects positron (or μ+, or pi+) and captures x-boson and grow. http://www.darkenergy.narod.ru/mh5.gif First, treating a proton as an elementary particle is a low energy ...

Re: Shut down
They're doing a lot of things that are best done with the LHC shut down, but the main thing seems to be qualifying the new quench protection systems for 3.5TeV/beam operation.

Re: Mini Black Holes
If mini black holes could exist, then virtual black holes would mediate proton decay. Proton decay has never been observed, and the lower bound on its rate means that there are no black holes below 10^16 GeV. That's around 12 orders of magnitude higher than the LHC can reach. So the LHC has no chanc...

Re: *** COLLISION ALERT ***
I notice on the LHC cryo page that the DFB45 temp is over 14 and rising fast. I guess the cryo for that is off right now.
Edit: That temp is now 17 and falling. It looks like they've fixed it.
