Hadron Definition and 62 Threads

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...

Why have I not seen equations that would tell the masses of hadrons as functions of other constants, like masses of quarks, and some coupling constants? After all, aren't the different hadrons merely different excitation states of some bound systems, and in principle it should be possible to...

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.

Homework Statement Find the the total spin of an n-quark hadron Homework Equations The Attempt at a Solution I'm totally stumped on this. Any hints would be greatly appreciated.

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...

Dominant decays of W/Z bosons are quark aintiquark pairs which decay into jets of hadrons. But how can a quark decay into a hadron? Surely as hadrons are bound states of quarks then hadrons are heavier and so quark->hadrons violates mass conservation (energy conservation). I know I'm...

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...
