Lhc Definition and 320 Threads

Im writing my first college essay, an analysis. I chose the large hadron collider because everyone else was doing healthcare reform and Iran testing warheads, thought this would be interesting. The only problem is I can't come up with a badass thesis statement for my essay, the thesis is due...

Short question. I know that COLLIDING beams are much more effective than when moving particle hits a target in observers reference frame. That is why they make a collider. However, when Oh My God particles are observed they actually hit something that something does not move. So, when...

Is it proper to say that when the LHC accelerates particles, those particles experience a mass increase? What is the Special Relativity explanation of the mass increase, i.e. do the particles have increased mass when observed in the rest frame of the detector or do the particles have the same...

The LHC is probably the last of the large accelerators so should the main contenders for the title of the theory of everything (if such a thing exists) now, at the dawn of the LHC start up, clearly state what findings would a) prove their theory b) support their theory & c) eliminate their...

The following is on CERN's website:

In 5 years or so, if LHC fails to find any superpartners, are ALL supersymmetric theories dead? Skippy

So the LHC is set to kick back on in September. How long will it be before we get results? How long do you think it will be before we find something new (if we do find something)? I remember hearing someone (I think my physics teacher) saying that it would be a few years before we get any real...

It is my understanding that physicists hope to use conservation of energy in the LHC to determine if there are multiple dimensions AND if there is dark matter. Let's suppose that through conservation of momentum, we detect a particle that apparently only reacts through gravity, and there is some...

If the LHC discovers energy evaporating to other branes, will the 'raisin pudding' analogy be abandoned in favor of the balloon analogy?

what would happen if the north pole was contained within the loop of the lhc at cern? the lhc at maximum speed can make a particle complete 7 loops in a second. the Earth rotates once every 24 hours. if the lhc was set up so the particle was made to move in the opposite direction to the...

Hey everyone, Okay so usually drell-yan is shown as interaction of p + p^bar: quark + antiquark -> virtual photon -> lepton(+) + lepton(-). I have seen diagrams of this for the LHC, which is a PROTON+PROTON collider yet drell-yan is still shown as an antiquark coming from one of the protons...

Hello, my understanding of particle physics is very limited. I know that several GUTs involving various symmetries have been proposed. My question is, wether experiments at the LHC can help to rule out or even verify some of the proposed GUTs? Maybe someone has some specific answers. Thank you!

If the LHC somehow observes the 4 th spatial dimension, does it mean we are on the verge of colapsing a probability wave and therefore determining the attributes of entire new dimension ?

Homework Statement I am writing about Particle Accelerators Homework Equations N/A The Attempt at a Solution I am writing an essay on particle accelerators, and I am trying to find out what type of accelerator the LHC actually is, but I cannot find anywhere that actually says...

I was curious as to whether or not there is potential for the magnetic field generated by the LHC to affect the Earth's magnetic field...

Peter Woit provides this link to a talk at CERN http://indico.cern.ch/getFile.py/access?contribId=92&sessionId=6&resId=1&materialId=slides&confId=22937 Slide 46 indicates that restart will not occur until late summer 2009 (Plan A) or sometime in 2010 (Plan B) The talk was given today by Jörg...

Why LHC use proton-proton collide instead of proton-antiproton(like,Tevatron) collide?

Hi all, I've learned that the LHC has just started. There are two beams of protons which travel clockwise and anti-clockwise at nearly the speed of light. Then the two beams are to colide into each other. My question is whether the speed of one beam compared to the other is at nearly 2 c ?

Can someone that has the data calculate what is the average energy in the large hadron collider beam at any moment of time. It's pretty straightforward, you have N particles which such and such speed and energy, you just sum up. I am not talking at all about the energy to support the...

So, what are the theories' predictions which are going to be tested on LHC? And if they won't be found, Does it mean they will be refuted or not?

What are the "Extra Dimensions" in the LHC experiment? First of all, I'd like you people to know that I'm a 10th grader. So yes, silly questions may follow. As the topic says, I want to have an idea of what the 'extra dimensions', that might possibly be discovered in the LHC experiment...

The present LHC schedule has first collisions scheduled for Thursday.

How will LHC know the Higgs when they "see" it? Amid the petabytes of information about to stream forth from Europe, how will Physics know if it has been wrong about the Higgs field and what may prove the premise? What's the best or worst case scenario, and what comes next?

What are your views on this? Assuming things continue to go all right what possible theoretical developments do you see as potential consequences? Just for context, here is a CERN press release A press release from CERN http://press.web.cern.ch/press/PressReleases/Releases2008/PR08.08E.html The...

For those interested: http://hasthelargehadroncolliderdestroyedtheworldyet.com/ I keep hitting refresh on my browser.

Frank Wilczek has brought out a book The Lightness of Being that is a perfect follow-up to Lee Smolin's The Trouble with Physics. Wilczek presents a vision of unification that is predicts phenomena at LHC energies, that is understandable and relevant in terms of today's experiments, and...

Hi Does anyone know if it's possible to see LHC launch tonight on TV in the United States (as opposed to webcast)? I have a FTA dish. There's nothing in Dish network program guide. CERN website shows a few satellites but the only one visible from continental United States is C-Band.

Hawking certainly will put his money where is mouth is. He has bet $100 that the http://www.physorg.com/news140161003.html" (or at least, one of the Higgs being predicted to be within the LHC energy range). So who is taking his bet? He does think that the LHC will find a supersymmetric partner...

:smile::smile: I think I am falling in love with the girl who wrote this song!:!) EDIT: Linked to Ryan's video instead.

Hi Chaps, As I'm sure we all are, I'm literally jumping up and down with excitement about next weeks first beam circulation - and only 31 days till the first collisions! Obviously, the CERN / LHC website is a great resource, but to someone who is still finding their feet in the particle...

hello I am a guy from China, and I am interested in LHC. At first I was convinced that the experiment in LHC would not produce any danger, but when I saw the passage below I was still terrified and afraid of it. http://bigsciencenews.blogspot.com/2008/05/nostradamus-and-lhc.html Can...

Hi why scientists picked up proton for LHC?

The real joke would be if nothing were found after all the money that has been spent on this project. Total Anti-Climax! No Higgs-Boson particle, No MBH, No Extra Dimensions, No Dark Matter, No Dark Energy...This would be a real disaster! It's better and healthier for Science that's ultimately...

I've been a little out of touch recently, and I don't know what's going on out there. Haven't they started running some beam tests? Everything okay so far?

Sorry to bug you all, but I have a question to ask. I have a bit of a worrying problem, so when I first heard about the LHC, some of the fear mongering got to me. However, after some research, my worrying nearly ceased. However, I ran into this paper today, and it says there may be a bit of a...

"Geneva, 7 August 2008. CERN1 has today announced that the first attempt to circulate a beam in the Large Hadron Collider (LHC) will be made on 10 September." http://press.web.cern.ch/press/PressReleases/Releases2008/PR06.08E.html

Photos of LHC - fantastic! i don't know if someone has already posted a link to these photos, but if you haven't seen them, check them out - totally incredible. man, i wish i worked there... http://www.boston.com/... .../2008/08/the_large_hadron_collider.html

Then check this out:

From what I gather, only more exotic, extra-dimensional theories predict that there will be microscopic black holes produced in the Large Hadron Collider. And I get that even if they are produced they are very unlikely to be stable and even then they would probably be safe (just to let you know...

Chris Morris (Brass eye, Nathan Barley etc etc), basically the funniest writer/comedian/whatever I can think of, visits the LHC for some elusive reason and writes an article in the Guardian, and records a podcast. For those (few) who are interested, the link is below...

I was reading a NY Times article on the lawsuit filed by Wagner and Sancho and amongst the usual doomsday predictions of black holes devouring the earth, strangelets turning the Earth to strange matter etc... It made the claim that What kinds of things are they referring to? I mean... i know...

I happened to see this comment of Kea's on a blog and thought it made good sense. Gil It is not at all reasonable to wait and see what happens at the LHC. Any responsible tax funded theoretician should be working their ass off to come up with quantitative predictions before 2009...

string theorists, will the LHC see SUSY and if not, will this be a huge blow? http://www.telegraph.co.uk/earth/main.jhtml?xml=/earth/2008/03/25/scibigbang125.xml http://www.telegraph.co.uk/earth/main.jhtml?xml=/earth/2008/03/25/scicomments125.xml NIMA ARKANI-HAMED “My hunch is that...

This may seem like a stupid question that's been brought up several times but it is regarding the possible creation of mini-black holes at the LHC. It's said that these MBH's pose no threat to the planet because of their small size and the fact that they will evaporate by Hawking radiation...

Hello all. I am a layperson that is very interested in science. I am particularly intrigued with what results the LHC will produce and how they affect the various existing theories. I was thinking that a central thread that links to and discusses various predictions on what the LHC will find...

The highest energy particle collisions ever attempted will begin at LHC at CERN near Geneva later this year. Are there any possible risks, even at an extremely low probability, from these experiments? Could we accidently trigger something like fusion? Could micro-black holes fuse and become a...

The Next Big Bang Premieres Sunday, March 16th at 8:00pm EST on The History Channel (Check local listings for other dates and times.) This year, the largest, most powerful science experiment in history will be turned on. The "Large Hadron Collider" at the CERN laboratory in Geneva Switzerland...

This is the text of the http://cerncourier.com/cws/article/cern/32522" at the recent celebration to commemorate the 50th Anniversary of the BCS Theory of Superconductivity. Considering it came from him, it should smash once and for all, the silly notion that condensed matter physics does not...

So, what will we see at the LHC if the Standard Model is all that there is to physics at this energy scale? What if there is no supersymmetry, no strings, no loops (or at least no emergent behavior that would be seen here)? Are we going to be able to tell if those theories are false pretty...

I'm sure that everyone is familiar with the Large Hadron colider under construction at CERN I am just curious about the hawking radiation that is to be produced to reveal the extra dimensions that are theorized by string theory. Hawking radiation as I understand it evaporates because of it's...
