What energy density expected at LHC point of collision?

[marcus]

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? what nominal volume is the kinetic energy spread out in?

but there should be some way to give a plausible rough figure for the energy density. experimental physicists are good at that kind of guesstimation.

So what do our experts in this department say?

Would you say it is closer to 10 GeV per cubic fermi
or to, say, 10¹⁶ GeV per cubic fermi?

The energy density at the point of collision is highly dependent on the type of collision that is taking place. It is typically much higher than 10 GeV per cubic fermi or 1016 GeV per cubic fermi. For example, in a proton-proton collision, the energy density can reach up to 1 TeV per cubic fermi. This number can be much higher in more powerful collisions such as those involving heavy ions.

The energy density at the point of collision at the LHC is expected to be extremely high, on the order of 1016 GeV per cubic fermi. This is due to the incredibly high energies of the colliding particles, which are accelerated to nearly the speed of light before being brought into collision.

To put this into perspective, the energy density at the LHC is about 100 trillion times higher than the energy density at the center of the sun. This is an incredibly high energy density, and it is necessary in order to create and study the fundamental particles and forces of the universe.

It is important to note that this energy density is not spread out over a large volume, but rather concentrated in a very small area at the point of collision. This allows for the creation of new particles and the study of their properties.

Experimental physicists use various techniques and calculations to estimate the energy density at the point of collision, taking into account the energies of the colliding particles and the size of the collision area. While there may be some variation in these estimates, it is generally agreed that the energy density at the LHC is extremely high.

In conclusion, the energy density at the point of collision at the LHC is expected to be on the order of 1016 GeV per cubic fermi, making it one of the most energetic environments in the universe.
