Does anyone know if the LHC could detect the graviton thx

One of the things that LHC will experimentally search for are supersymmetric partners of the Standard-Model particles. Maybe it will found them, maybe it will not. But what if it will? The existence of supersymmetry does not imply the existence of superstrings. However, string theory is...

Hi i was just wondering what the possible dangers of the LHC (Large Hadron Collider) were? I've heard that there could be the creation of miniture black holes, which sounds to me like a bad idea! i take it that they could grow! I know people say that they will evaporate, but what if their...

The Large Hadron Collider will not be ready in time to perform a low-energy "engineering run", which was originally scheduled to take place this November, according to an official at CERN. This will leave the operators no chance to gain experience with the particle accelerator's steering and...

I'm not sure how much this has been covered on this board, but I have a few questions regarding the hypothetical doomsday scenarios involving the LHC. 1) I've heard that mini-black holes could be created at LHC, but that they are supposed to evaporate. How can we be sure that they will? Is it...

I'm more used to seeing colliders rated by the kinetic energy of the colliding particles, but just recently I've been seeing estimates of the ENERGY DENSITY to be expected right at the point of collision. This raises doubts about exactly what is meant. what is the nominal area of collision...

If LHC does not see SUSY-partners, of course, this null result would not falsify all SUSY theories, as some SUSY theories could still be realized in nature at a breaking scale some point above 1 TEV, but would a null result falsify SUSY theories that serve as an explanation for hierarchy of the...

I was reading about the LHC and came across the term "bunch crossing" in this sentence "The bunch crossing time will be 25ns and at full luminosity there will be approximately 22 proton-proton collisions per bunch crossing. " It seems obvious that this means the protons are coming in bunches...

This is a general question. When will the LHC be ready to power up its first collision?

See: http://user.web.cern.ch/user/QuickLinks/Announcements/2007/LHCInnerTriplet.html" What's the latest news on the LHC? How bad is the damage? How long will the delay be?

Everyone might have time to polish their theory. http://www.fnal.gov/pub/today/20070329_page01.html Fermilab Statement on LHC Magnet Test Failure

2000 odd Tonnes of Magnet has just been installed into the new CERN LHC complex. Not being a Quantum Physicist can one of you clever chaps tell me what would happen if "we ventured into realms long regarded as those of speculative science fiction -- multiple universes, parallel worlds...

Thanks Lubos, Dear Lubos, Does string theory offer a concrete prediction for the mass of the higgs boson? Thanks Dan PS would you mind if I cross-post your response at sci.physics or PF? dan | 10.01.06 - 5:58 pm | # Dear dan, string theorists - just like everyone else - are...

Should the Tevatron see the Higgs boson? Given that it can collide at the TEV scale, shouldn't this be enough to see the HIGGS BOSON? What-if LHC does not observe the Higgs boson? Obviously this is bad for the standard model. Would this disconfirm string theory? Can the standard model...

How exactly will LHC detect superpartners? Presumably they will have higher mass, are there other ways to detect them?

Does anyone know what the LHC will be capable of when it's running at high speed? I haven't really been able to find what kind of experiments the physicists will be able to perform with the collider. Just wandering what the plan was for this baby, what we can expect to learn, etc.

The model that Lisa Randall and Raman Sundrum propose consists of two four dimensional (Minkowskian) branes, bounding a five dimensional bulk between them. In their initial model the branes are very close together; this is not a "large extra dimensions" model. The motivation of the model is...

What do you think will we discover with the LHC? And what will we learn from it? Reference: http://arxiv.org/abs/hep-ph/0602198" I.e. how realistic do you think is the discovery of extra-dimensions, black holes, supersymmetry, the one more probable than the other, and what if (!) they...

Does anybody know where to get the expected cross section for Z at the LHC (pp at 14 TeV)? (it would be great if you could provide a reference).

Gather round thinkers...:) I would like to know if anyone here is acquainted with Dr. Paul Dixon's theory and speculation on the accidental creation of a supernova by experimentation in particle accelerator's. This is a very deep subject that first came up in 1998. Dr. Dixon appears to be...
