I know that for any coliders beams are not exactly the same size but they can be approximated to the same value as the deviation is relatively small, such as LHC. My questions:
1- are there currently working or planned colliders with unequal beam sizes?
2- for coliders of different particles...
Hi,
I was asking how fast is the fastest Hadron ever moved in the large Hadron collider.And most importantly how do they calculate it? Do the calculate it mathematically or with a detector?
Or, is that that the hadrons are large? Or, are they both large? What exactly is the adjective "large" qualifying please? I do know that the tunnel is very large indeed, and that this is the most sophisticated machine ever built.
the higgs naturalness problems has several solutions
1- natural susy
2- technicolor
3- extra dimensions
4- conformal invariance
Large Hadron Collider has to date strongly disfavored susy, technicolor, extra dimensions. it is highly unlikely susy is the answer to the higgs hierarchy problem...
I am doing a piece of A-2 coursework concerning the LHC and its restart and cannot understand why the increase in energy of run 2 would allow us to detect heavier particles such as those proposed by SUSY.
It's to my understanding that the Large Hadron Collider is so 'large' due to the fact E=MC^2 and that when the accelerated particles approach the speed of light their mass increases logarithmic to a near infinite mass, meaning the magnetic force applied to the particle, to stop it from touching...
Hey physics enthusiasts,
I have been reading and watching various videos, which talks about the possibility that the Higgs particle which was discovered by collisions in the large hadron collider(LHC) may not be the standard model Higgs particle. What does this mean? What is the difference...

Due to the blogs being removed, I thought it might be worthwhile posting a few in the forums-The Large Hadron Collider has produced collisions at 7 TeV. For collisions at 7 TeV, protons need to be ‘ramped’ to 3.5 TeV, the proton has a mass of 1.6726e−27 kg which, according to mass–energy...

It seems like once you get to the upper levels engineering and physics start to blend together. For example, think of the Large Hadron Collider.

I am a programmer and physics fan. A speaker (Lawrence Krauss?) at https://origins.asu.edu/events/great-debate-parallel-realities-probing-fundamental-physics (not on youtube yet) said physics theories beyond the standard model are an under-determined problem. There are 7,000 theories that fit...

i've studied in my 9th standard that x rays are produced when cathode rays(electrons) hit solid targets such as molybdenum,titanium,etc..

Peter Higgs is going to get a Nobel prize for physics, since Higgs boson's existence was confirmed in the experiments in CERN.

I was on the LHC simulator and the collisions of the Hydrogen atoms were confusing. Why were some uniform in direction while some spinning erratically in a cork screw pattern? Does that behavior have anything to do with the positive or negative charges of the Quarks in the nucleus?
I had a look at the production cross sections for W/Z at hadron colliders. These differ as a function of energy with the W x-sec being consistently ~10 times larger than the Z cross sections. Why is the W cross section so much larger? I think the coupling strength is similar and the mass...

so according to wiki: protons have a Lorentz factor of about 7,500 and move at about 0.999999991 c, or about 3 metres per second slower than the speed of light (c)
If we consider speed of Earth's rotation or speed at which two galaxies approach each other (collision or otherwise)?
I'm currently reading about the parton model and deep inelastic scattering.
As I've understood it was observed that when protons collided at high energy very little transverse momentum transfer was observed, while when electrons were collided with protons transverse momentum transfer was...
This was released today so I'm not sure if most have seen it yet. It appears that "a" Higgs Boson is confirmed.

With CERN's Large Hadron Collider being in the news recently, I began to think of a question that bothered me for years about particle accelerators.

In a large hadron collider at CERN, protos follow a circular path with speeds close to the speed of light. X-rays can be produced by free protons which are accelerating.

Take for instance putting the large hadron collider in space at a near absolute zero where you never have to put energy into cool down the system. The LHC takes 10 GJ to run and the total energy of the two beams is 724 MJ. [1] Since the power to run the system never experiances resistence, would...

The tunnel of the Large Hadron Collider is 27.00 km long. The LHC accelerates protons to a speed of 0.999997828 times the speed of light. How long would it take the proton to pass through the tunnel according to an observer at rest with respect to the building? To an observer...
I was watching a show the other night about the Large Hadron Collider, and I got to wondering how much force it would take to push two uranium nuclei right up against each other. I figured it would be on the order of a thousandth, maybe a millionth of a pound, which seems like a lot, considering...
One of the aims of the Large Hadron Collider is that it may be able to re-create conditions in the early universe and therefore produce the quark-gluon plasma that appeared microseconds after the universe's birth.
