Collider Definition and 67 Threads

In a video I watched, which I can't find now, Leonard Susskind briefly mentions something about scientists recently creating what seemed to be a black hole in a collider (not the LHC). He said that the scientists needed to use string theory and extra dimensions to make sense of it. Something...

A few days ago the Large Hadron Collider (LHC) was finished. Pretty rare no one started this topic. What you guys say about the LHC?? I hope they find the Higgs Boson and find a lot of the mysteries of the Big Bang and the universe. Here is the...

So they didn't seem to collide any particles yet? I'm not too knowledgeable about this topic, but it must be something "landmark" as Google altered their logo to inform people about this. Anyways, there's a link to the article here...

http://www.lhcountdown.com/?p=13#comments The countdown is close to the end! Anyone know when we should expect results of new (or lack of) finds? I mean public announcement. A day? A week? 72 years!?

I would like to hear what your thoughts are about the Large Hadron Collider they are going to fire up in August? Think were making a doom's day product?

Hello All This is a question from a complete physics ingnoramus, and a quick search on google brought this forum up as a good place to start! Also, apologies if I'm in the wrong bit of the forum. Right, the question. I've been reading about the Large Hadron Collider in Cern, and it keeps...

Hi, I have no academic grounding in advanced physics, but I have read a lot of the popular books on physics, and am generally interested in it. (In a couple of years that's probably what I'll learn in college). Anyway, there are people who are afraid that when the LHC goes on this summer we...

Hi! I was wondering how W+/- pairs can be created in an electron/positron collider. Does the e+e- form a Z^0 which decays to W^- W^+ ? http://www.particle.kth.se/zlab/project/Elep.gif I have found this picture, but there is no info about the mediating particle (in the small...

I understand that if black holes were created in the LHC, they should evaporate in 10^-100 seconds and be created at 1 black hole per second. The collider produces 10^8 collisions per second. The lifespan of a black hole increases with mass^3. I was wondering whether it would be possible for a...

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...

Two Russian Mathematicians claim that the Large Hadron Collider (being built in Switzerland) has the potential to "tear holes" in spacetime. Here is their paper written from the http://www.mi.ras.ru/index.php?l=1" http://arxiv.org/pdf/0710.2696 Just curious on people's thoughts.

I was just wondering about the International Linear Collider and the Tesla Cavities. okay as i see it they run a 9 cell cavity with a field strength of 222kW RF at 1.3 ghz and a beam current of 8.5 ma. my question is if they doubled the cavities to 18, what rf field strength would they need to...

Are there any signature differences between SUSY and extra dimensions ? Any papers you can link?

Today's issue of the Science Times features a long article by Dennis Overbye on the Large Hadron Collider. It includes some pictures credited to Physics World, Sept. 2004, from which credit I presume the "particle sprays" are in fact either simulations or else do not depict ATLAS data--- my...

Just read this article on the International Linear Collider http://physicsweb.org/articles/news/11/2/10/1 Looks like it's going to be a six-and-a-half-billion-dollars, 31 Km long collider that can reach energies of "500 gigaelectronvolts." Also, it seems, that they might consider...

I've read here http://lhc.web.cern.ch/lhc/general/gen_info.htm about the LHC buing under construction at CERN and they say that it will collide protons and other ions at very high speeds , but they don't say what new particles are expected to appear ,or what theories do they expect to be...
