I've been search through google to find out if there has been anything on missing energy so far, i have found nothing. Is there any evidence for or against extra dimensions?
fzero said:No evidence for extra dimensions has been found. In the absence of of new physics, model-dependent limits can be placed on the possible size of extra dimensions. The most recent CMS paper on extra dimensions seems to be http://arxiv.org/abs/arXiv:1103.4279, while the Atlas results are older http://arxiv.org/abs/1012.4272.

What energy levels can we rule out extra dimensions?
A/4 said:The paper you cite is conjecture on possible signals. In reality, no missing energy has been found, nor evidence for extra dimensions. The lower-limit placed on any modified Planck scale is about 4 TeV, based on the fact that no mini-black holes (that is, their evaporation profiles) have been observed.
Missing energy, also known as "dark energy", refers to the energy that cannot be detected or accounted for in a particle collision at the Large Hadron Collider (LHC). It is important because it could potentially provide evidence for new particles or interactions that cannot be explained by current theories.
No, as of now, missing energy has not been definitively discovered at the LHC. Several experiments have observed hints of missing energy, but more research is needed to confirm these findings and determine their significance.
The LHC uses powerful particle accelerators to smash particles together at high speeds. By analyzing the energy and momentum of the particles before and after the collision, scientists can search for any discrepancies that may indicate missing energy.
If missing energy is discovered at the LHC, it could have significant implications for our understanding of the universe and the fundamental laws of physics. It could potentially provide evidence for new particles or interactions that could revolutionize our current theories.
One of the biggest challenges in the search for missing energy at the LHC is distinguishing it from other sources of energy that may be present in a particle collision. Scientists must carefully analyze and interpret data to ensure that any observed discrepancies are truly due to missing energy and not experimental error or background noise.
