Has missing energy been discovered at the LHC?

[eiyaz]

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?

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.

Wow no missing energy huh?

What energy levels can we rule out extra dimensions?

Those papers give values. For example the scale in the Atlas paper excludes extra dimensions whose radii are greater than 10^-19 m, which is around one ten-thousandth of the size of a proton.

I found these links that seems to suggest there was missing energy discovered in 2010, am I interpreting these correctly?:

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.

What about the first link?
